What is the nature of thermal energy? What is heat at the atomic level? Give a discussion and several examples. Would it make any sense to speak of the temperature of an atom? Solution 1) Heat is a formation of thermal energy, that is transferred between two substances due to temperature difference.Thermal energy cause change in the state of matter.(solid to liquid and liquid to gas..etc).Thermal energy is depends on average kinetic energy of molecules in the system.Thermal energy can transfer in three different ways..that is Conduction,convection and radiation. Examples: Suns thermal energy heats the atmosphere. Ice is addded to water, thermal energy in the water melts the ice. 2) Matter made of atoms and molecules. Heat added to the substance, the atoms and molecules vibrates faster, which increase the molecular motion and finally substance expands.Convection is one of the example for atomic level of heat. 3) Temperature of atom is conceptually incorrect. This is because, from the gas law, the average kinetic energy gas molecules(not atoms) is directly proportional to the absolute temperature.Therefore single particle or atom canot have a temperature..

1. How are temperature and heat different concepts? 2. How does the specific heat of water compare to the specific heat of other common materials? Why is this important? Solution 1. There is a fundamental difference between temperature and heat. Heat is the amount of energy in a system. The SI units for heat are Joules. A Joule is a Newton times a meter. A Newton is a kilogram-meter per second squared. Heat is transferred through radiation, conduction and convection. The amount that molecules are vibrating, rotating or moving is a direct function of the heat content. Energy is transported by conduction as molecules vibrate, rotate and/or collide into each other. Heat is moved along similar to dominos knocking down their neighbors in a chain reaction. An increase of electromagnetic radiation into a system causes the molecules to vibrate, rotate and/or move faster. With convection, higher energy molecules are mixed with lower energy molecules. When higher energy molecules are mixed with lower energy molecules the molecular motion will come into equilibrium over time. The faster moving molecules will slow down and the slow moving molecules will speed up. Temperature is the MEASURE of the AVERAGE molecular motions in a system and simply has units of (degrees F, degrees C, or K). Notice that one primary difference between heat and temperature is that heat has units of Joules and temperature has units of (degrees F, degrees C, or K). Another primary difference is that energy can be transported without the temperature of a substance changing (e.g. latent heat, ice water remains at the freezing point even as energy is brought into the ice water to melt more ice). But, as a general statement (ignoring latent heat), as heat energy increases, the temperature will increase. If molecules increase in vibration, rotation or forward motion and pass that energy to neighboring molecules, the measured temperature of the system will increase. 2. Water has one of the highest specific heat capacities known. There are however a few substances whose specific heat capacity is higher A large body of water can absorb and store a huge amount of heat from the sun in the daytime and during summer while warming up only a few degrees. And at night and during winter, the gradually cooling water can warm the air. This is the reason coastal areas generally have milder climates than inland rtegions. The high specific heat of water also tends to stabilize ocean temperatures, creating a favorable environment for marine life. THus because of its high specific heat, the water that covers most of Earth keeps temperature fluctuations on land and in water within limits that permit life. Also, because organisms are primarily made of water, they are more able to resist changes in their own temperature than if they were made of a liquid with a lower specific heat. .

Hello! Can someone help me to answer Task4 and Task7: Complete \"TODO\" in this files: AssignCompiler.scala AssignInstrs.scala AssignRuntime.scala Task4: It is about handling conditional statements. The statement can be assign. For example, a=5; This is already done. Now, we need to handle if statement. For example, if(false) { x := x + 1 } { x := 0 } which is if Expr stmt* stmt*. (stmt*) many statements. This is all the definition: Prog ::= Stmt* Stmt ::= Identifier = Expr | if Expr Stmt* Stmt* Expr ::= Identifier | Literal | Expr {+,-,/,*,&&,||,=} Expr | {-,!} Expr Literal ::= Number | true | false Identifier ::= String Task7 same idea but with while loop. # Conditionals In the first part of this exercise, we extend the Assign language with conditional statements. Syntax of the Assign language with conditionals Prog ::= Stmt* Stmt ::= Identifier = Expr | if Expr Stmt* Stmt* Expr ::= Identifier | Literal | Expr {+,-,/,*,&&,||,=} Expr | {-,!} Expr Literal ::= Number | true | false Identifier ::= String Task 1: Define the SOS relations for expressions and programs that add conditionals to the assign language. Provide traces for 3 different programs. Done # Compile conditionals We compile conditionals to a machine that features only two instructions: one for assignment as before and one for conditional jumps. Instr ::= Idx = Expr | jumpif Number Expr For `jumpif`, the first component describes the target program counter, which must be a constant number. The second component describes the condition under which the jump takes place. That is, a jump only takes place if the condition evaluates to `true` and is skipped otherwise. We reuse machine states unchanged: State ::= (Prog, PC, Heap) PC ::= Number Heap ::= empty | Literal; Heap Task 2: Define the semantics of the Assign language with conditionals as a state transition relation. Provide traces for 3 different programs. Done # Implementation of conditionals To gain a detailed understanding of the Assign language with conditionals and to facilitate experimentation, we will implement the compiler and the abstract machine of the language in Scala. We use [SBT](http://www.scala-sbt.org/) for building the project and [ScalaTest](http://www.scalatest.org/) for testing. To compile the project, run `sbt compile` on the command-line. With `sbt test` you can execute the tests. Task 3: Study the code of the Assign language and add two tests for programs with assignments to `AssignTest.scala`. Done Task 4: Implement conditionals for the Assign language. We already extended the expression type with conditionals. Please do not change any of the signatures of expressions, because this makes it impossible for us to test your code! To solve this task, add conditionals jumps to the instructions, extend the compiler to handle conditionals and extend the runtime of the abstract machine to handle conditional jumps. Add at least 3 tests to `AssignTest.scala`, that test programs containing conditionals. # The While l.

Given technology today, would it be more feasible than in the past for the United States to become more of a direct democracy than a republic? What would be the benefits? The drawbacks? What did we learn from Athenian democracy, the Enlightenment, and our founders that would argue against making democracy more direct? Solution US is not a democracy and it is a republic is a false polarity. It is a political arrangement in which power and control lies in the delegates. In the Government by the general population, democracy is practiced through the chosen agents. If we talk about an Direct democracy, laws and choices are made by a government which has larger majority. The legislature might be monarchical, aristocratically, or, democratical. America has a constitutional democracy. Courts can control the just will. The US Government is the Constitutional Federal delegate democracy. One can request a move towards a Direct democracy, yet it can make representing troublesome if there should be an occurrence of a coalition. Likewise, passing laws is troublesome if there should arise an occurrence of a govern of a substantial number of little parties. Basic natural rights, social agreements are credited to Enlightment. In the fourth century, Athens can be deciphered as a social contract. In a Direct democracy, general people pick options that boost a person\'s welfare. An arrangement of techniques are picked, and, a political structure changes based on these systems. Popular governments attempt to search for an optimal rate of progress. Neoclassical theory is the benchmark for an optimal rate of political change. Athens was a advanced arrangement of direct democracy. General people could present proposition before the leadership body. The Athenian direct democracy accomplished a harmony amongst instability, and, solidness. The model of decision in a Direct democracy demonstrates the likelihood of Pareto improvement arrangements when compensatory installments are permitted.

Explain in detail how OFDM helps mitigates multipath fading effects. Thank you! As detailed as possible! Solution Multipath fading is a feature that needs to be taken into account when designing or developing a radio communications system. In any terrestrial radio communications system, the signal will reach the receiver not only via the direct path, but also as a result of reflections from objects such as buildings, hills, ground, water, etc that are adjacent to the main path.The overall signal at the radio receiver is a summation of the variety of signals being received. As they all have different path lengths, the signals will add and subtract from the total dependent upon their relative phases. At times there will be changes in the relative path lengths. This could result from either the radio transmitter or receiver moving, or any of the objects that provides a reflective surface moving. This will result in the phases of the signals arriving at the receiver changing, and in turn this will result in the signal strength varying as a result of the different way in which the signals will sum together. It is this that causes the fading that is present on many signals. Multipath fading can affect radio communications channels in two main ways. This can give the way in which the effects of the multipath fading are mitigated..

In addition, analyze the way claims are made, based on these two different approaches. Provide at least one example for each. Solution Scientific inquiry Source :Husband and Wife Differences in Response to Undesirable Life Events In our society today we have so many dynamics to a “family.” Many things factor into these rolls and they are not things that were seen 10 or even 5 years ago! We have woman’s rights, equality, Stay at home fathers, gay rights, and single parent homes. The divorce rate is higher than ever and what was normal for a family last year is not the same today by any means. After reading the study you realize that the author is testing about how certain stressors in a person’s life can affect them in different ways depending on what sex they are. The author states that men and woman deal with things on a different level and each process things in a different manor. Whereas, something that may affect a man, will not have as much bearing on a woman and vies versa. Woman tested were more prone to psychological problems like depression and anxiety. Men tested were more likely to demonstrate other symptoms of distress such as alcohol or drug use. They believed that men would become more hostile about situations and woman would be anxious about the same situation In the present study of 451 married couples living in the rural midwest, gender differences were examined in reports of exposure and vulnerability to specific types of undesirable life events. Consistent with expectations derived from either a social structural or identity perspective, the results demonstrated that men are more likely than women to report exposure to and to be distressed by work and financial events. Women, on the other hand, are more strongly influenced by exposure to negative events within the family but not within their network of friends. Outcomes vary according to the type of emotional distress. Financial stress, for example, increases hostility among men more than among women, but wives are more likely than husbands to report somatic complaints in response to the same stressor. The findings demonstrate the need for future research that more directly investigates the intraindividual and social mechanisms which account for gender differences in a broad range of emotional and behavioral responses to varying types of significant life changes. Inquiry is a natural human activity; that is, people seek a general understanding about the world around them. We recognize that present circumstances affect future circumstances. We learn that getting an education will determine the amount of money we earn later in life. The key to inquiry is observation. We can never understand the way things work without first having something to understand. Understanding through experienc.

Describe and illustrate the use of a bank reconciliation in controlling cash, & Describe the Sarbanes-Oxley Act of 2002 and its impact on internal controls and financial reporting. Solution Answers The use of bank reconciliation in controlling cash Bankreconciliation is a necessary process to identify potential errors, fraud or irregularities, and it enables the company to make proper adjustments to its cash-account balance. Bank reconciliation provides an independent, external record of a company\'s cash flows. Most companies prepare a detailed cash budget that is reviewed and updated on a regular basis. The cash budget lays out projected cash inflows and outflows over a given time period as part of the company\'s cash-management plan. The Sarbanes-Oxley Act of 2002 and its impact on internal controls In the wake of the 2001-2002 Arthur Andersen accounting scandal and collapse of Enron and WorldCom, the government, the investors and the American public demanded corporate reforms to prevent similar future occurrences. Viewed to be largely a result of failed or poor governance, insufficient disclosure practices, and a lack of satisfactory internal controls, in 2002 Congress passed the Sarbanes-Oxley Act seeking to set standards and guarantee the accuracy of financial reports. After a prolonged period of corporate scandals in the United States from 2000 to 2002, the Sarbanes-Oxley (SOX) was enacted in July 2002 to restore investors\' confidence in the financial markets and close loopholes that allowed public companies to defraud investors. The act had a profound effect oncorporate governance in the U.S. The Sarbanes-Oxley Act requires public companies to strengthen audit committees, perform internal controls tests, make directors and officers personally liable for accuracy of financial statements, and strengthen disclosure. The Sarbanes-Oxley Act also establishes stricter criminal penalties for securities fraud and changes how public accounting firms operate.

What is the threat to culture by a \"read-only world,\" and how do the CC licenses provided by Lessig address this threat? Solution The primary argument against the current state of copyright is the length of copyright. As stated above, the Constitution established copyright for a “limited period”. In the first one hundred years of United States history, the term of copyright was increased once (to a 42 year maximum). In the next fifty years, the term was increased once more (to a maximum of 56 years). In the past forty years, Congress has increased the terms of existing and future copyrights; most recently, in 1998, Congress extended existing copyrights by twenty years (Lessig Free Culture ). This prevents many works from entering the “public domain” and becoming part of the common culture. A good example of this is Walt Disney’s “Steamboat Willie”, the first appearance of Mickey Mouse. Before the 1998 copyright amendments, “Steamboat Willie” would have become public domain in 2003: now, it is under copyright until 2023, assuming the law is not changed again. This is particularly ironic, given that Walt Disney and the Disney corporation have made extensive use of “public domain” works (such as The Hunchback of Notre Dame and Treasure Island) in their own production of derivative copyrighted works. Indeed, “Steamboat Willie” is itself a parody of a contemporary Buster Keaton film, “Steamboat Bill Jr.” (Lessig Free Culture ) “Fair use” is a controversial provision in copyright law because it is not clearly defined. The U.S. Copyright Office states “The distinction between fair use and infringement may be unclear and not easily defined. There is no specific number of words, lines, or notes that may safely be taken without permission” (“Fair Use”). In practice, it is up to the user to defend his “fair use” right and bear the legal costs of doing so. Jon Else, a documentary filmmaker, was quoted a $10,000 fee to license four and a half seconds of a Simpsons episode that was playing in the background of one scene in a documentary about opera. When he suggested that this was covered under “fair use”, Fox (the copyright distributor) threatened to sue him, leading Else to edit the scene . In some cases, it is difficult or impossible to find the original copyright owner, especially since copyright registration is no longer required. These works are commonly called “orphan works”. Without permission, these works cannot be reprinted or redistributed, and disappear from the culture. When Carnegie Mellon attempted to obtain permission to digitize works in their libraries, they found that 22% of the publishers of those works could not be contacted (“Report on Orphan”). If the owners or publishers of a work cannot be contacted, there is no way to reach an agreement on reprinting and reproduction rights. Without such an agreement, the work in question will eventually become unavailable, except possibly through resellers of used media or through illicit chann.

What is one hypothesis to explain why there are more endemic bird species on Sulawesi than on Borneo? Solution Sulawesi is an island found in Indonesia and it is found between the Borneo and Maluka islands. Sulawesi island contains the one endemic bird ground dwelling chicken sized maleo, a m egapode. This endemic bird uses the hot sand to incubate it\'s eggs and that are evolved from volcanic eruptions. There are more endemic species of birds in Sulawesi than in Borneo because of its geological time , evergreen islands, climatic conditions, speciation and isolation may lead to the possible favorable conditions to the endemic bird species. Due to the climatic conditions like lofty mountains, misty lakes, cool mossy highland forests, fertile valleys with greenary and low land rain forest are the reasons to be more endemic bird species in Sulawesi than in Borneo. Thus the hypothesis and reasons to have more endemic bird species in Sulawesi than in Borneo..

What are the ethical tensions in advertising? Who are the responsible parties for keeping advertising ethical and what is their specific responsibilities? Solution Q1) The major ethical tensions in advertising include Puffery and Deception of consumers. Puffery is the exaggerated claim by a firm regarding its products or services through advertising to attract the consumers to purchase their products. Deception or false advertising is when the firm’s advertising on its products or services turns out to be completely false.

Use the following information to answer the next Question. The graphs of four polynomial functions are shown below. Match three of the graphs numbered above with a statement below that best describes the function. The graph that has a negative leading coefficient is graph number___, The graph of a function that has two different zeros, each with multiplicity 2, is graph number ___ The graph that could be a degree 5 function is graph number ___. Solution 7. i) Graph with -ve leading coefficient : odd-degree polynomials have ends that head off in opposite directions. If they start \"down\" (entering the graphing \"box\" through the \"bottom\") and go \"up\" (leaving the graphing \"box\" through the \"top\"), they\'re positive polynomials; if they start \"up\" and go \"down\", they\'re negative polynomials. So, option graph 1 ii) Graph with two different zeros with multipicity 2 will have graph touching x axis at two points.It will not cut x axis Graph 2 iii) Graph with degree 5 i.e. odd degree Graph 4 cuts the axis at 3 points and it touches the x axis at 1 point ( root with multiplicity 2) : 3 +2 = degree 5.
