A benefit of an activity received by people not participating in the activity is called a(n) Solution Assuming the question is in terms of economics, the answer is Positive Externality Externality is a phenomena in which a proportion of cost (negative externality) or benefit (positive externality) an activity is received by someone who did\'t participate in the activity. In case a cost is incurred it is termed as negative externality, while in case of benefit is received, it is termed as positive externality. Consider education - a learning activity, in an underdeveloped country. In poor area, if there is an initiative of education, and children are educated by any welfare institution or government, that education would not only affect the child individually, but also would affect his family in a positive manner. The household people might learn somethings which they didn\'t knew before, that can save them in many ways, such as importance of hygene like washing hands before having food, or caring for mortals, etc. This is the case of positive externality, as even though the adult didn\'t attend the education, they did received the benefit. Education also reduces crime, and hence society as a whole benefits. Another examples of positive externality are low income people who do not pay taxes does recieve state welfare, military-defence protention, and enjoy many other public goods, like street light, roads, etc. The opposite of positive externality is negative externality. Suppose a polluting industry is placed in a poor agricultural area, and it will pollute the land and or water and or by dumping wastes and smokes of byproducts. People who don\'t work and have no relation to the industry would also be affected in an adverse manner. Yet some proportion of the population now have more stable income, but many others who didn\'t participate in the activity are affected. Farmers doing pisciculture and agriculture would be affected by dead fishes or bad crop, or general public breathing polluted air would incur several health cost. All kinds of pollution which are not natural (like pollution by volcanic eruption), are examples of negative externality..

How does law enforcement, courts and corrections work to complemen.pdf
How does law enforcement, courts and corrections work to complement each other ? What
would happen if one branch of the system were Brocken?
How does law enforcement, courts and corrections work to complement each other ? What
would happen if one branch of the system were Brocken?
Solution
There are three branches of justice system
Let us talk about these.
Law Enforcement- It includes the first investigation done by police. The police investigate first
and arrest to the suspects. Then after they approach court for further procedures. Here police
force cannot punish the suspect as per their understandings. They have to maintain the peace and
harmony in the country.
Courts- Now when the matter has moved to court now court will ask for clues and proofs and
witness for the matter. After analyzing the witness, proofs and other things the court defines the
guilty and punish as per the crime.
3. Corrections:- Now when the court has given it’s judgment, next step is followed by the
correctness. It means the guilty will be enforced. This may includes jail, probation, fine, etc,
Earlier there was capital punishment for brutal cases but now a days it is closed in some
countries because of human rights organizations.
The benefit of this is this removes the criminal from the society and society is safe from those
criminals. Other people have fear about the punishment so they stop the wrong doings.
So I have described you how the procedures are connected with each other. If one branch is
broken whole the system will be failed. If law enforcement is failed the suspects will not under
arrest and further procedures will not take place. If there is no court then there will be no
punishment. All the punishment will be given by police so there may be injustice in the society.
And if correction is failed then the guilty will remain in society and society will have probability
of occurrence of crime again..
Check all that apply to different sets of genes that are homologous..pdf
Check all that apply to different sets of genes that are homologous.
A.have similar biochemical activities (ex. bind to DNA, synthesize polypeptides)
B.exist in the same species
C. exist in the same individual
D.have different cellular functions (ex. cell division, transport to membranes)
E.have different biochemical activities (ex. bind to DNA, synthesize polypeptides)
F. have similar cellular functions (ex. cell division, transport to membranes)
G. exist in different species
******I have already tried: similar biochemical activities, have similar cell function, and exist in
different species I got half credit for this so i must be missing something.
Solution
Answer
Homologous chromosomes are chromosome pairs, one from each parent that is similar in length,
gene position and centromere location. The position of genes on each homologous chromosome
is the same, however the genes may contain different alleles.
A. have similar biochemical activities.
B. exist in same species.
F. have similar cellular functions like cell division and transport to membranes.
G. Homologous chromosomes may exist in different species. For example, drosophila genes are
homologous with genes of human beings.
So the answer would be A, B, F, and G..

For the following matrices, determine a cot of basis vectors for the null spaces the column
spaces. A = [3 2 -1 5] A = [2 1 -3 4 0 2 0 -2 8] Let P_n denote the set of all polynomial
functions of degree at most n Let a_o be a feed constant. Explain why H = [p(t) = a_0 + b_x| b
R} is not necessarily a vector subspace of P_x, Are there any values of a_o for which H will be a
subspace? If instead H = {p(t) = a + bt| a, b R}, (i.e., the constant term is allowed to vary over
all real numbers), show that H is a vector subspace of P_n.

A matrix, in general sense, represents a
collection of information stored or arranged
in an orderly fashion. The mathematical
concept of a matrix refers to a set of numbers,
variables or functions ordered in rows and
columns. Such a set then can be defined as a
distinct entity, the matrix, and it can be
manipulated as a whole according to some
basic mathematical rules.
A matrix with 9 elements is shown below.

A computer monitor with 800 horizontal
pixels and 600 vertical pixels can be viewed as
a matrix of 600 rows and 800 columns.
In order to create an image, each pixel is
filled with an appropriate colour.

Exploring Organizational Culture
Research the ITT Tech Virtual Library to find an article each on the following types of
organizational culture:
Constructive
Passive/Defensive
Aggressive/Defensive
Now, answer the following questions:
What were the norms of each culture, and how were they determined?
What were the behaviors in each culture, and how did those behaviors impact the organization
and why?
Of the three organizational cultures, which one would you prefer to be a part of and why
2 pages
Solution
in constructive approach people are encouraged to interact with others, with the co-employees,
understand each other, make a strong group and work to achieve organizational goals. this
culture are focus in which members are encouraged to interact withpeople and approach tasks in
ways that will help them meet their higher order satisfaction needs. in positions where people do
a complex job, rather than something simple like a mechanic one, this culture is efficient.
here employees are become more friendly in nature and builds strong relationships among them.
aggressive/defensive organizational culture:tThis style is characterized with more emphasis on
task than people. because of the very nature of this style, people tend to focus on their own
individual needs at the expense of the success of the group. the aggressive/defensive style is very
stressful, and people using this style tend to make decisions based on status as opposed to
expertise.
the people who are workholics they will be benefited in this kind of cultures. people will be
selfish and only task oriented here. they wont consider the feelings and emotions of employees.
passive and defensive culture: in organizations with Passive/Defensive cultures, members feel
pressured to think and behave in ways that are inconsistent with the way they believe they should
in order to be effective. People are expected to please others (particularly superiors) and avoid
interpersonal conflict. Rules, procedures, and orders are more important than personal beliefs,
ideas, and judgment. Passive/Defensive cultures experience a lot of unresolved conflict and
turnover, and organizational members report lower levels of motivation and satisfaction.
based on the nature of work and importance, one can choose an organizational culture. for me the
constructive approach is more better and gives positive results..

Define the labor relations processSolutionThe labor relations.pdf
Define the labor relations process?
Solution
The labor relations process involves managers (representing the ownership interests) and a labor
organizations (union), selected by employees as their exclusive bargaining agent to represent
their interests and engaging in the joint determination and administration of work rules.
Three basic phases of the labor relations process are as follows:
1) Recognition of the legitimate rights and responsibilities of union and management
representatives.
2) Negotiation of the labor agreement, including appropriate strategies, tactics, and impasse
resolution techniques.
3) Administration of the negotiated labor agreement — the interpretation and application of labor
contract terms on a daily basis..
Accounting 5205Solution Depreciation aims to recognize in the.pdf
Accounting 5205
Solution
? Depreciation aims to recognize in the income statement the wear suffered by an asset on
account of its use for the generation of income.
The objective of depreciation is not to recover the investment that the company has made for its
construction or acquisition. The investment is recovered through the profitability generated by
the use of said asset.
? Long-term assets, also known as non-current assets, although they are durable, are not always
eternal. Therefore, accounting forces depreciate assets as their normal lives pass, with the
accepted general accounting principle of time period, equity, valuation at cost, accrued,
objectivity, because they do so naturally by the passing of time, due to its use, due to the wear
and tear of the time this asset is used, in order to reflect its best possible value, or to amortize
long-term expenses (deferred assets). For this there are tables and methods for accounting
treatment..

Aiom for the ADT List. C++ Explain what this pseudocode is doing.
aList.getEntry(i) = (aList.insert(i, item)).getEntry(i+1)
Solution
You have a list
and we know list has index starting from
0, 1,2,3,4,5,6,.....
So
(aList.insert(i, item)): Inserts item at index i
(aList.insert(i, item)).getEntry(i+1) : Inserts item at index i and fetches and returns the element
at index i+1
aList.getEntry(i) = (aList.insert(i, item)).getEntry(i+1)
So, it means (aList.insert(i, item)).getEntry(i+1) Inserts item at index i and fetches and returns
the element at index i+1 and assigns it to element at index i..

an encryption scheme distributes randomly over the Ascii characters 32-127
What is the 8-bit entropy??
Solution
An encryption scheme we use must convert plain text to human readable cipher.
We here convert 32 ASCI to 127 character.
The transmitter send the message through the channel.The channel modifies the message in some
way.Then the receiver then finds which message is send.The probability expected value of the
information contained in each message is called entropy .The 8 -bit entropy is mostly used for
finding the value..
A class has 40 students aged 17 to 34. What is the probabilty that a.pdf
A class has 40 students aged 17 to 34. What is the probabilty that at least two students are the
same age? Why?
Solution
Here we have that P(atleast two same ages )= 1- P(no same age)
Now total favorable cases for no same age are 34-17= 18 ( as all will be of different ages)
Thus Probability ( different ages ) = Total favorable case/total case =18/40
And accordingly Probability (atleast two same ages ) =1-18/40 = 22/40 = 11/20
So last required answer is 11/20..
A microbial geneticist isolates a new mutation in E. coli and wishes.pdf
A microbial geneticist isolates a new mutation in E. coli and wishes to map its chromosomal
location. She uses interrupted-mating experiments with Hfr strains and generalized-transduction
experiments with phage P1. Explain why each technique, by itself, is insufficient for accurate
mapping.
Solution
Hfr cells undergoing conjugation transfer host genes in a linear fashion. The genes transferred
depend on both the Hfr strain and the length of time during which the transfer occurred.
F factors arise from improper excision of an Hfr from bacterial chromosome. They can have only
specific bacterial genes on them because the integration site is fixed for each strain.
P1 does not recognize pseudo-pac sites on the chromosome. P1 seems to begin packaging from
random double-stranded breaks on the chromosome that are generated during phage infection.
Generalized transduction is the process by which any bacterial gene may be transferred to
another bacterium via a bacteriophage, and very rarely a small number of phages carry the donor.
A restricted set of genes will not be able to transfer by this method. She wanted to transfer a
specific gene to a specific located which is not doen by generalized transduction, so accurate
gene mapping will be difficult by these methods..

1)Please explain the commands ifconfig, ping, traceroute, netstat, d.pdf
1)Please explain the commands ifconfig, ping, traceroute, netstat, dig, nslookup, route, host,
hostname.
2). Explain briefly about TCP/IP and its Protocol Architecture.
3) Explain the difference between TCP/IP Protocol stack and OSI model.
Solution
Answer:
1) Ipconfig
Ipconfig is an MS-DOS utility that can be used from MS-DOS and an MS-DOS shell to display
the network settings currently assigned and given by a network. This command can be utilized to
verify a network connection as well as to verify your network settings.
Ping
Ping is one of the most commonly used network commands that allows you to ping another
network IP address. Pinging another address helps determine if the network card can
communicate within the local network or outside network.
Netstat
The netstat command is used to display the TCP/IP network protocol statistics and information.
Nslookup
The nslookup MS-DOS utility that enables a user to do a reverse lookup on an IP address of a
domain or host on a network.
Route
The route MS-DOS utility enables computers to view and modify the computer\'s route table.
traceroute
The tracert command in MS-DOS and Windows (known as traceroute in Unix-like operating
systems) is a useful tool for diagnosing network issues. It allows you to view a listing of how a
network packet travels through the network and where it may fail or slow down. Using this
information you can determine the computer, router, switch or other network device possibly
causing your network issues.
host
solves a host name into an Internet Protocol (IP) address or an IP address into a host name.
the hostname command is used to show or set a computer\'s host name and domain name. It is
one of the most basic of the network administrative utilities.
A host name is a name that is assigned to a host (i.e., a computer connected to the network) that
uniquely identifies it on a network and thus allows it to be addressed without using its full IP
address. Domain names are user-friendly substitutes for numeric IP addresses.
The basic syntax for the hostname command is
hostname [options] [new_host_name]
2)TCP/IP protocols map to a four-layer conceptual model known as the DARPA model , named
after the U.S. government agency that initially developed TCP/IP. The four layers of the DARPA
model are: Application, Transport, Internet, and Network Interface. Each layer in the DARPA
model corresponds to one or more layers of the seven-layer Open Systems Interconnection (OSI)
model.
Network Interface Layer
The Network Interface layer (also called the Network Access layer) is responsible for placing
TCP/IP packets on the network medium and receiving TCP/IP packets off the network medium.
TCP/IP was designed to be independent of the network access method, frame format, and
medium. In this way, TCP/IP can be used to connect differing network types. These include
LAN technologies such as Ethernet and Token Ring and WAN technologies such as X.25 and
Frame Relay. Independence from any specific ne.
At what point does commercialization start to create inequality Ple.pdf
At what point does commercialization start to create inequality? Please provide examples.
Solution
Markets and commerce change the character of the goods they touch.Such deliberations touch,
unavoidably, on competing conceptions of the good life.For fear of disagreement, we hesitate to
bring our moral and spiritual convictions into the public square.It simply means that markets will
decide them for us.At a time of rising inequality, the commercialization of everything means that
people of affluence and people of modest means lead increasingly separate lives. We live and
work and shop and play in different places. Children go to different schools. It’s not good for
democracy, nor is it a satisfying way to live.Democracy does not require perfect equality, but it
does require that citizens share a common life. What matters is that people of different
backgrounds and social positions encounter one another, and bump up against one another, in the
course of everyday life. For this is how we learn to negotiate and abide by our differences, and
how we come to care for the common good.
The public schools are an integral part of the institutions of democracy. By schools, Human
Capital forms which eventually helps a country to faster its growth and substantially move
forward.If we are to achieve the democratic ideal of equity, there must be a commons, and it
must be accessible for all to participate effectively. Public education is an important part of that
commons. But this common education is not fee, and only those can grab this oppurtunity who
are able to pay for it.Commercialization encloses the commons and puts up fences, with
admission only to those who can pay. It privatizes public space. It makes the dollar, not
citizenship, the entry point to educational experiences and social and political influence in a
democratic society..
You are given a specification for some Java classes as follows. A.pdf
You are given a specification for some Java classes as follows.
A building has a number of floors, and a number of windows.
A house is a building.
A garage is a building.
A room has a length, width, a floor covering, and a number of closets.
You can never create an instance of a building, but every object that is a building must have a
method that calculates the floor space, i.e., the Building class is abstract, and has an abstract
method.
A house has a number of bathrooms, and an array of Rooms.
A house has a method that returns the average size of the Rooms.
A Garage can hold some number of cars, and it may have a cement floor or a gravel floor. A
garage has a length and a width. (Don’t use the Room class as a member of the Garage class.)
Object
/ \\
Building Room
/ \\
House Garage
2. Implement the specification.
You must use the following mechanisms correctly:
· Inheritance – is a
· Composition – has a
· Constructor methods
· Accessor / mutator methods = getters, setters
· Arrays of objects
· Passing arrays of objects to methods
· Abstract classes and methods
· Access modifiers – public private
o might not need protected, a you should never use
· toString() methods
· the super keyword
· method overriding
· interfaces
· generics are introduced
· polymorphism using inheritance, and interfaces
Include a test class that has a main method. This test program will make instances of your classes
and output the text representation of the objects using the toString() methods. There should be
enough comments in the output so that it is easy to see which classes are being tested.
In your test class, create an ArrayList. Add a couple of houses and garages to your list. Loop
through the list, using the enhanced for loop. Print out the objects using the toString methods.
(The toString methods should return a String object containing all of the instance variables’
values.)
Additional Requirements:
Only methods used for testing will call the System.out.println() method. The purpose of the
classes is to store and manipulate data. Input and output is not included in the data storage and
manipulation classes.
A house will calculate its floor space by looping through the array of rooms, and accumulating
the floor space. Don\'t worry about the space used by a closet, you can assume that it is included
in the size of the room.
Work incrementally. Start by making a Room class, and testing it. Then make the Building and
Garage classes, test them. The make the house class, and test it.
The constructor for the house class has an array of rooms as a parameter.
The building class is the only class that stores and manipulates the number of windows, and
number of floors.
All garage objects have exactly one floor. Perhaps the Building class should have an overloaded
constructor to accommodate this.
Interface
Add an interface to your package. Call the interface MLSListable. That means that a class that
implements this interface is a property that can be listed for sale. T.
8. Would the following cell have a spontaneous reaction Explain. .pdf
8. Would the following cell have a spontaneous reaction? Explain.
Solution
A redox reaction is spontaneous if the standard electrode potential for the redox reaction,
Eo(redox reaction), is positive.
Eo(redox reaction) = Eo(reduction reaction) + Eo(oxidation reaction)
and Eo(redox reaction) > 0
that is, Eo(redox reaction) is positive
If Eo(redox reaction) is positive, the reaction will proceed in the forward direction
(spontaneous).
Spontaneous redox reactions can be used to produce electricity
(see galvanic cells (voltaic cells)).If Eo(redox reaction) is negative (Eo(redox reaction) < 0), the
reaction will not proceed in the forward direction (non-spontaneous).This reaction will be non
spontaneous redox reactions cannot be used to produce electricity.
E standard potential value is positive so reaction is non spontaneously.

Write a program that mimics the operations of several vending machin.pdf
Write a program that mimics the operations of several vending machines. More specifically, the
program simulates what happens when the user chooses one of the vending machines, inputs
money and picks an item from the vending machine. Assume there are two vending machines:
one for drinks and one for snacks. Each vending machine contains several items. The name,
price, and quantity of each item is given in two text files; one named “drinks.txt” for the drinks
vending machine and the other named “snacks.txt” for the snacks vending machine.
The format of the input values is comma-separated. The items listed should be organized in the
file with the following order: name, price, quantity. Here are some example items:
The actual reading and parsing of the input file is already handled in the class supplied to you
(see code on BlackBoard). You are given the variables as individual values. You will need to
create the .txt files for creating and testing your vending machines.
You will need to create/complete three classes for this homework assignment: Item,
VendingMachine, and VendingMachineDriver.
Problem Description
Milk,2.00,1
Within your VendingMachine class, include these methods:
VendingMachineThisconstructormethodwilltakeinthenameoftheinputfileand create a vending
machine object. A vending machine object will contain an array of Item objects called stock and
an amount of revenue earned. This constructor method has been completed for you and should
work appropriately once you have completed the rest of this class and the other class definitions.
vendThismethodwillsimulatethevendingtransactionafteravalidamountofmoney and an item
selection are entered. This method will decide if the transaction is successful (enough money or
item) and update the vending machine appropriately.
outputMessage This method will print an appropriate message depending on the success of the
transaction. If the user does not have enough money to buy the chosen item, the vending machine
should prompt the user to enter more money or exit the machine. If the vending machine is out of
the chosen item, the program will print an apology message and prompt the user to choose
another item or exit the machine. If there is enough money for the item selected, then the
vending machine will give the user the item and return the change.
printMenuThismethodprintsthemenuofitemsforthechosenvendingmachine. The Item class needs
to include the following data variables:
• description as a String
• price as a double
• quantity as an int
Within your VendingMachineDriver class, include a main method as the starting point for your
solution that creates the vending machine objects appropriately and then use a loop that

How does law enforcement, courts and corrections work to complemen.pdf
How does law enforcement, courts and corrections work to complement each other ? What
would happen if one branch of the system were Brocken?
How does law enforcement, courts and corrections work to complement each other ? What
would happen if one branch of the system were Brocken?
Solution
There are three branches of justice system
Let us talk about these.
Law Enforcement- It includes the first investigation done by police. The police investigate first
and arrest to the suspects. Then after they approach court for further procedures. Here police
force cannot punish the suspect as per their understandings. They have to maintain the peace and
harmony in the country.
Courts- Now when the matter has moved to court now court will ask for clues and proofs and
witness for the matter. After analyzing the witness, proofs and other things the court defines the
guilty and punish as per the crime.
3. Corrections:- Now when the court has given it’s judgment, next step is followed by the
correctness. It means the guilty will be enforced. This may includes jail, probation, fine, etc,
Earlier there was capital punishment for brutal cases but now a days it is closed in some
countries because of human rights organizations.
The benefit of this is this removes the criminal from the society and society is safe from those
criminals. Other people have fear about the punishment so they stop the wrong doings.
So I have described you how the procedures are connected with each other. If one branch is
broken whole the system will be failed. If law enforcement is failed the suspects will not under
arrest and further procedures will not take place. If there is no court then there will be no
punishment. All the punishment will be given by police so there may be injustice in the society.
And if correction is failed then the guilty will remain in society and society will have probability
of occurrence of crime again..
Check all that apply to different sets of genes that are homologous..pdf
Check all that apply to different sets of genes that are homologous.
A.have similar biochemical activities (ex. bind to DNA, synthesize polypeptides)
B.exist in the same species
C. exist in the same individual
D.have different cellular functions (ex. cell division, transport to membranes)
E.have different biochemical activities (ex. bind to DNA, synthesize polypeptides)
F. have similar cellular functions (ex. cell division, transport to membranes)
G. exist in different species
******I have already tried: similar biochemical activities, have similar cell function, and exist in
different species I got half credit for this so i must be missing something.
Solution
Answer
Homologous chromosomes are chromosome pairs, one from each parent that is similar in length,
gene position and centromere location. The position of genes on each homologous chromosome
is the same, however the genes may contain different alleles.
A. have similar biochemical activities.
B. exist in same species.
F. have similar cellular functions like cell division and transport to membranes.
G. Homologous chromosomes may exist in different species. For example, drosophila genes are
homologous with genes of human beings.
So the answer would be A, B, F, and G..

A matrix, in general sense, represents a
collection of information stored or arranged
in an orderly fashion. The mathematical
concept of a matrix refers to a set of numbers,
variables or functions ordered in rows and
columns. Such a set then can be defined as a
distinct entity, the matrix, and it can be
manipulated as a whole according to some
basic mathematical rules.
A matrix with 9 elements is shown below.

organizational culture:
Constructive
Passive/Defensive
Aggressive/Defensive
Now, answer the following questions:
What were the norms of each culture, and how were they determined?
What were the behaviors in each culture, and how did those behaviors impact the organization
and why?
Of the three organizational cultures, which one would you prefer to be a part of and why
2 pages
Solution
in constructive approach people are encouraged to interact with others, with the co-employees,
understand each other, make a strong group and work to achieve organizational goals. this
culture are focus in which members are encouraged to interact withpeople and approach tasks in
ways that will help them meet their higher order satisfaction needs. in positions where people do
a complex job, rather than something simple like a mechanic one, this culture is efficient.
here employees are become more friendly in nature and builds strong relationships among them.
aggressive/defensive organizational culture:tThis style is characterized with more emphasis on
task than people. because of the very nature of this style, people tend to focus on their own
individual needs at the expense of the success of the group. the aggressive/defensive style is very
stressful, and people using this style tend to make decisions based on status as opposed to
expertise.
the people who are workholics they will be benefited in this kind of cultures. people will be
selfish and only task oriented here. they wont consider the feelings and emotions of employees.
passive and defensive culture: in organizations with Passive/Defensive cultures, members feel
pressured to think and behave in ways that are inconsistent with the way they believe they should
in order to be effective. People are expected to please others (particularly superiors) and avoid
interpersonal conflict. Rules, procedures, and orders are more important than personal beliefs,
ideas, and judgment. Passive/Defensive cultures experience a lot of unresolved conflict and
turnover, and organizational members report lower levels of motivation and satisfaction.
based on the nature of work and importance, one can choose an organizational culture. for me the
constructive approach is more better and gives positive results..

Define the labor relations processSolutionThe labor relations.pdf
Define the labor relations process?
Solution
The labor relations process involves managers (representing the ownership interests) and a labor
organizations (union), selected by employees as their exclusive bargaining agent to represent
their interests and engaging in the joint determination and administration of work rules.
Three basic phases of the labor relations process are as follows:
1) Recognition of the legitimate rights and responsibilities of union and management
representatives.
2) Negotiation of the labor agreement, including appropriate strategies, tactics, and impasse
resolution techniques.
3) Administration of the negotiated labor agreement — the interpretation and application of labor
contract terms on a daily basis..
Accounting 5205Solution Depreciation aims to recognize in the.pdf
Accounting 5205
Solution
? Depreciation aims to recognize in the income statement the wear suffered by an asset on
account of its use for the generation of income.
The objective of depreciation is not to recover the investment that the company has made for its
construction or acquisition. The investment is recovered through the profitability generated by
the use of said asset.
? Long-term assets, also known as non-current assets, although they are durable, are not always
eternal. Therefore, accounting forces depreciate assets as their normal lives pass, with the
accepted general accounting principle of time period, equity, valuation at cost, accrued,
objectivity, because they do so naturally by the passing of time, due to its use, due to the wear
and tear of the time this asset is used, in order to reflect its best possible value, or to amortize
long-term expenses (deferred assets). For this there are tables and methods for accounting
treatment..

Aiom for the ADT List. C++ Explain what this pseudocode is doing.
aList.getEntry(i) = (aList.insert(i, item)).getEntry(i+1)
Solution
You have a list
and we know list has index starting from
0, 1,2,3,4,5,6,.....
So
(aList.insert(i, item)): Inserts item at index i
(aList.insert(i, item)).getEntry(i+1) : Inserts item at index i and fetches and returns the element
at index i+1
aList.getEntry(i) = (aList.insert(i, item)).getEntry(i+1)
So, it means (aList.insert(i, item)).getEntry(i+1) Inserts item at index i and fetches and returns
the element at index i+1 and assigns it to element at index i..

an encryption scheme distributes randomly over the Ascii characters 32-127
What is the 8-bit entropy??
Solution
An encryption scheme we use must convert plain text to human readable cipher.
We here convert 32 ASCI to 127 character.
The transmitter send the message through the channel.The channel modifies the message in some
way.Then the receiver then finds which message is send.The probability expected value of the
information contained in each message is called entropy .The 8 -bit entropy is mostly used for

A class has 40 students aged 17 to 34. What is the probabilty that at least two students are the
same age? Why?
Solution
Here we have that P(atleast two same ages )= 1- P(no same age)
Now total favorable cases for no same age are 34-17= 18 ( as all will be of different ages)
Thus Probability ( different ages ) = Total favorable case/total case =18/40
And accordingly Probability (atleast two same ages ) =1-18/40 = 22/40 = 11/20
So last required answer is 11/20..
A microbial geneticist isolates a new mutation in E. coli and wishes.pdf
A microbial geneticist isolates a new mutation in E. coli and wishes to map its chromosomal
location. She uses interrupted-mating experiments with Hfr strains and generalized-transduction
experiments with phage P1. Explain why each technique, by itself, is insufficient for accurate
mapping.
Solution
Hfr cells undergoing conjugation transfer host genes in a linear fashion. The genes transferred
depend on both the Hfr strain and the length of time during which the transfer occurred.
F factors arise from improper excision of an Hfr from bacterial chromosome. They can have only
specific bacterial genes on them because the integration site is fixed for each strain.
P1 does not recognize pseudo-pac sites on the chromosome. P1 seems to begin packaging from
random double-stranded breaks on the chromosome that are generated during phage infection.
Generalized transduction is the process by which any bacterial gene may be transferred to
another bacterium via a bacteriophage, and very rarely a small number of phages carry the donor.
A restricted set of genes will not be able to transfer by this method. She wanted to transfer a
specific gene to a specific located which is not doen by generalized transduction, so accurate
gene mapping will be difficult by these methods..

1)Please explain the commands ifconfig, ping, traceroute, netstat, d.pdf
1)Please explain the commands ifconfig, ping, traceroute, netstat, dig, nslookup, route, host,
hostname.
2). Explain briefly about TCP/IP and its Protocol Architecture.
3) Explain the difference between TCP/IP Protocol stack and OSI model.
Solution
Answer:
1) Ipconfig
Ipconfig is an MS-DOS utility that can be used from MS-DOS and an MS-DOS shell to display
the network settings currently assigned and given by a network. This command can be utilized to
verify a network connection as well as to verify your network settings.
Ping
Ping is one of the most commonly used network commands that allows you to ping another
network IP address. Pinging another address helps determine if the network card can
communicate within the local network or outside network.
Netstat
The netstat command is used to display the TCP/IP network protocol statistics and information.
Nslookup
The nslookup MS-DOS utility that enables a user to do a reverse lookup on an IP address of a
domain or host on a network.
Route
The route MS-DOS utility enables computers to view and modify the computer\'s route table.
traceroute
The tracert command in MS-DOS and Windows (known as traceroute in Unix-like operating
systems) is a useful tool for diagnosing network issues. It allows you to view a listing of how a
network packet travels through the network and where it may fail or slow down. Using this
information you can determine the computer, router, switch or other network device possibly
causing your network issues.
host
solves a host name into an Internet Protocol (IP) address or an IP address into a host name.
the hostname command is used to show or set a computer\'s host name and domain name. It is
one of the most basic of the network administrative utilities.
A host name is a name that is assigned to a host (i.e., a computer connected to the network) that
uniquely identifies it on a network and thus allows it to be addressed without using its full IP
address. Domain names are user-friendly substitutes for numeric IP addresses.
The basic syntax for the hostname command is
hostname [options] [new_host_name]
2)TCP/IP protocols map to a four-layer conceptual model known as the DARPA model , named
after the U.S. government agency that initially developed TCP/IP. The four layers of the DARPA
model are: Application, Transport, Internet, and Network Interface. Each layer in the DARPA
model corresponds to one or more layers of the seven-layer Open Systems Interconnection (OSI)
model.
Network Interface Layer
The Network Interface layer (also called the Network Access layer) is responsible for placing
TCP/IP packets on the network medium and receiving TCP/IP packets off the network medium.
TCP/IP was designed to be independent of the network access method, frame format, and
medium. In this way, TCP/IP can be used to connect differing network types. These include
LAN technologies such as Ethernet and Token Ring and WAN technologies such as X.25 and
Frame Relay. Independence from any specific ne.
At what point does commercialization start to create inequality Ple.pdf
At what point does commercialization start to create inequality? Please provide examples.
Solution
Markets and commerce change the character of the goods they touch.Such deliberations touch,
unavoidably, on competing conceptions of the good life.For fear of disagreement, we hesitate to
bring our moral and spiritual convictions into the public square.It simply means that markets will
decide them for us.At a time of rising inequality, the commercialization of everything means that
people of affluence and people of modest means lead increasingly separate lives. We live and
work and shop and play in different places. Children go to different schools. It’s not good for
democracy, nor is it a satisfying way to live.Democracy does not require perfect equality, but it
does require that citizens share a common life. What matters is that people of different
backgrounds and social positions encounter one another, and bump up against one another, in the
course of everyday life. For this is how we learn to negotiate and abide by our differences, and
how we come to care for the common good.
The public schools are an integral part of the institutions of democracy. By schools, Human
Capital forms which eventually helps a country to faster its growth and substantially move
forward.If we are to achieve the democratic ideal of equity, there must be a commons, and it
must be accessible for all to participate effectively. Public education is an important part of that
commons. But this common education is not fee, and only those can grab this oppurtunity who
are able to pay for it.Commercialization encloses the commons and puts up fences, with
admission only to those who can pay. It privatizes public space. It makes the dollar, not
citizenship, the entry point to educational experiences and social and political influence in a
democratic society..
You are given a specification for some Java classes as follows. A.pdf
You are given a specification for some Java classes as follows.
A building has a number of floors, and a number of windows.
A house is a building.
A garage is a building.
A room has a length, width, a floor covering, and a number of closets.
You can never create an instance of a building, but every object that is a building must have a
method that calculates the floor space, i.e., the Building class is abstract, and has an abstract
method.
A house has a number of bathrooms, and an array of Rooms.
A house has a method that returns the average size of the Rooms.
A Garage can hold some number of cars, and it may have a cement floor or a gravel floor. A
garage has a length and a width. (Don’t use the Room class as a member of the Garage class.)
Object
/ \\
Building Room
/ \\
House Garage
2. Implement the specification.
You must use the following mechanisms correctly:
· Inheritance – is a
· Composition – has a
· Constructor methods
· Accessor / mutator methods = getters, setters
· Arrays of objects
· Passing arrays of objects to methods
· Abstract classes and methods
· Access modifiers – public private
o might not need protected, a you should never use
· toString() methods
· the super keyword
· method overriding
· interfaces
· generics are introduced
· polymorphism using inheritance, and interfaces
Include a test class that has a main method. This test program will make instances of your classes
and output the text representation of the objects using the toString() methods. There should be
enough comments in the output so that it is easy to see which classes are being tested.
In your test class, create an ArrayList. Add a couple of houses and garages to your list. Loop
through the list, using the enhanced for loop. Print out the objects using the toString methods.
(The toString methods should return a String object containing all of the instance variables’
values.)
Additional Requirements:
Only methods used for testing will call the System.out.println() method. The purpose of the
classes is to store and manipulate data. Input and output is not included in the data storage and
manipulation classes.
A house will calculate its floor space by looping through the array of rooms, and accumulating
the floor space. Don\'t worry about the space used by a closet, you can assume that it is included
in the size of the room.
Work incrementally. Start by making a Room class, and testing it. Then make the Building and
Garage classes, test them. The make the house class, and test it.
The constructor for the house class has an array of rooms as a parameter.
The building class is the only class that stores and manipulates the number of windows, and
number of floors.
All garage objects have exactly one floor. Perhaps the Building class should have an overloaded
constructor to accommodate this.
Interface
Add an interface to your package. Call the interface MLSListable. That means that a class that
implements this interface is a property that can be listed for sale. T.
8. Would the following cell have a spontaneous reaction Explain. .pdf
8. Would the following cell have a spontaneous reaction? Explain.
Solution
A redox reaction is spontaneous if the standard electrode potential for the redox reaction,
Eo(redox reaction), is positive.
Eo(redox reaction) = Eo(reduction reaction) + Eo(oxidation reaction)
and Eo(redox reaction) > 0
that is, Eo(redox reaction) is positive
If Eo(redox reaction) is positive, the reaction will proceed in the forward direction
(spontaneous).
Spontaneous redox reactions can be used to produce electricity
(see galvanic cells (voltaic cells)).If Eo(redox reaction) is negative (Eo(redox reaction) < 0), the
reaction will not proceed in the forward direction (non-spontaneous).This reaction will be non
spontaneous redox reactions cannot be used to produce electricity.
E standard potential value is positive so reaction is non spontaneously.

Write a program that mimics the operations of several vending machin.pdf
Write a program that mimics the operations of several vending machines. More specifically, the
program simulates what happens when the user chooses one of the vending machines, inputs
money and picks an item from the vending machine. Assume there are two vending machines:
one for drinks and one for snacks. Each vending machine contains several items. The name,
price, and quantity of each item is given in two text files; one named “drinks.txt” for the drinks
vending machine and the other named “snacks.txt” for the snacks vending machine.
The format of the input values is comma-separated. The items listed should be organized in the
file with the following order: name, price, quantity. Here are some example items:
The actual reading and parsing of the input file is already handled in the class supplied to you
(see code on BlackBoard). You are given the variables as individual values. You will need to
create the .txt files for creating and testing your vending machines.
You will need to create/complete three classes for this homework assignment: Item,
VendingMachine, and VendingMachineDriver.
Problem Description
Milk,2.00,1
Within your VendingMachine class, include these methods:
VendingMachineThisconstructormethodwilltakeinthenameoftheinputfileand create a vending
machine object. A vending machine object will contain an array of Item objects called stock and
an amount of revenue earned. This constructor method has been completed for you and should
work appropriately once you have completed the rest of this class and the other class definitions.
vendThismethodwillsimulatethevendingtransactionafteravalidamountofmoney and an item
selection are entered. This method will decide if the transaction is successful (enough money or
item) and update the vending machine appropriately.
outputMessage This method will print an appropriate message depending on the success of the
transaction. If the user does not have enough money to buy the chosen item, the vending machine
should prompt the user to enter more money or exit the machine. If the vending machine is out of
the chosen item, the program will print an apology message and prompt the user to choose
another item or exit the machine. If there is enough money for the item selected, then the
vending machine will give the user the item and return the change.
printMenuThismethodprintsthemenuofitemsforthechosenvendingmachine. The Item class needs
to include the following data variables:
• description as a String
• price as a double
• quantity as an int
Within your VendingMachineDriver class, include a main method as the starting point for your
solution that creates the vending machine objects appropriately and then use a loop that
continues interacting with the vending machines until the user enters “X” to exit. See the sample
session for details.
As you implement your solution, you might find that some methods contain some repeated
coding logic. To avoid unnecessary redundancies in your code, have these method.

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

A benefit of an activity received by people not participating in the.pdf
- 1. A benefit of an activity received by people not participating in the activity is called a(n) Solution Assuming the question is in terms of economics, the answer is Positive Externality Externality is a phenomena in which a proportion of cost (negative externality) or benefit (positive externality) an activity is received by someone who did't participate in the activity. In case a cost is incurred it is termed as negative externality, while in case of benefit is received, it is termed as positive externality. Consider education - a learning activity, in an underdeveloped country. In poor area, if there is an initiative of education, and children are educated by any welfare institution or government, that education would not only affect the child individually, but also would affect his family in a positive manner. The household people might learn somethings which they didn't knew before, that can save them in many ways, such as importance of hygene like washing hands before having food, or caring for mortals, etc. This is the case of positive externality, as even though the adult didn't attend the education, they did received the benefit. Education also reduces crime, and hence society as a whole benefits. Another examples of positive externality are low income people who do not pay taxes does recieve state welfare, military-defence protention, and enjoy many other public goods, like street light, roads, etc. The opposite of positive externality is negative externality. Suppose a polluting industry is placed in a poor agricultural area, and it will pollute the land and or water and or by dumping wastes and smokes of byproducts. People who don't work and have no relation to the industry would also be affected in an adverse manner. Yet some proportion of the population now have more stable income, but many others who didn't participate in the activity are affected. Farmers doing pisciculture and agriculture would be affected by dead fishes or bad crop, or general public breathing polluted air would incur several health cost. All kinds of pollution which are not natural (like pollution by volcanic eruption), are examples of negative externality.
