Task: Write a Java program to implement a simple graphics editor that can be used to draw a
Pythagoras. The editor has a pull-down menu on top of the screen, with 2 buttons: \"Pythagoras\"
and \"Quit\". 1) When the user selects \"Pythagoras\", he/she can draw a tree of Pythagoras on
the screen. 2) The editor terminates/quits execution if the user selects \"Quit\" from the pulldown
menu. 3) The editor has a horizontal and a vertical sliding bar that when slided, moves the tree
on the canvas accordingly.

Applet in java
Applet is the client site designing in Java. To design applet there is a need to use applet api of java. Applet is the class of java applet package. It also uses the AWT api to design the client site. Applet has a life cycle. Applet does not have main function. To run appet we need to write HTML code. We can debug the applet in appletviewer also.

A rigid- well-insulated gas cylinder contains N0 moles of an ideal gas.docx
A rigid, well-insulated gas cylinder contains N0 moles of an ideal gas at a temperature To  and pressure Po. A venting valve is opened and the gas is pumped out of the tank. Derive an expression for the instantaneous temperature in the cylinder as a function of the number of moles of gas remaining in the cylinder. What is the final temperature Tf, if the tank is evacuated to Nf = 0? Is the prediction physically realistic? The heat  capacity at constant volume of the gas is independent of temperature.
Solution
PV = nRT
nT = PV/R = constant
nT = K
Tdn + ndT = 0
Tdn = - ndT
dT/dn = - T/n
dT/T = -dn/n
Integrating both sides
ln T = - ln n + C
at n=No ; T =To
so
ln To = - ln No + C
C = ln To + ln No = ln To*No
so
ln T = ln To*No - ln n
ln T = ln (To*No/n)
T = (To*No)/n
as n = Nf = 0
Twill tend to infinity...this is not practically possible

A simple camera telephoto lens consists of two How far behind the conc.docx
A simple camera telephoto lens consists of two How far behind the concave lens should the film be placed? Express your answer using two significant figures concave lens with a focal length f210.1 cm The object to be photographed is 4.01 m in front of the objective lens. cm Submit Part B What is the linear magnification of this lens combination? Express your answer using two significant figures.
Solution
The image from the first (convex) lens is formed at a distance i1 from the object
1/o1 + 1/i1 = 1/f1
1/401 + 1/i1 = 1/39
i1 = 43.2 cm
This image is formed 43.2 - 36.0 = 7.2 cm behind the second lens. That becomes the virtual image of the convex lens at i2 = -7.2 cm.
The object for that image is 1/o2 + 1/i2 = -1/f2
1/o2 - 1/7.2 = -1/10.1
o2 = 25.1 cm
o2 is actually the image of the lens system (interchange object and image in the concave lens formula).
Image i1 has magnification 43.2/401 = 0.108, and the image i2 has magnification 25.1/7.2 = 3.5. Overall magnification is 0.108*3.5 = 0.378

A priniciple purpose of a representation letter from management is to-.docx
A priniciple purpose of a representation letter from management is to:
Solution
Management representation is a letter issued by an auditor\'s client to the auditor in writing as one of audit evidences. The date of the document must not be later than the date of audit work completion. It is used to let the client\'s management declare in writing that the financial statements and other presentations to the auditor are sufficient and appropriate and without omission of material facts to the financial statements, to the best of the management\'s knowledge. it is a form letter written by a company\'s external auditors, which is signed by senior company management.
The letter states that all of the information submitted is accurate, and that all material information has been disclosed to the auditors. The auditors use this letter as part of their audit evidence. The letter also shifts some blame to management, if it turns out that some elements of the audited financial statements do not fairly represent the financial results, condition, or cash flows of the business.

A process or task in Linux is represented by a Answer data structure-S.docx
A process or task in Linux is represented by a Answer data structure.
Solution
Linux can manage the processes in the system, each process is represented by a task_struct data structure (task and process are terms that Linux uses interchangeably). The task vector is an array of pointers to every task_struct data structure in the system.
Each process on the system is in exactly one of five different states. This value is represented by one of five flags:
TASK_RUNNING:
The process is runnable; it is either currently running or on a runqueue waiting to run.This is the only possible state for a process executing in user-space; it can also apply to a process in kernel-space that is actively running.
TASK_INTERRUPTIBLE:
The process is sleeping (that is, it is blocked), waiting for some condition to become true or a signal is received. When this condition exists, the kernel sets the process\'s state to TASK_RUNNING. The process can awake and become runnable if it receives a signal.
TASK_UNINTERRUPTIBLE:
This state is identical to TASK_INTERRUPTIBLE except that it does not wake up and become runnable if it receives a signal. This is used in situations where the process must wait without interruption or when the event is expected to occur quite quickly. Because the task does not respond to signals in this state, TASK_UNINTERRUPTIBLE is less often used than TASK_INTERRUPTIBLE6.
TASK_ZOMBIE:
The task has terminated, but its parent has not yet issued a wait4() system call. The task\'s task structure must remain in case the parent wants to access it. If the parent calls wait4(), the task structure is deallocated.
TASK_STOPPED:
Process execution has stopped; the task is not running nor is it eligible to run. This occurs if the task receives the SIGSTOP, SIGTSTP, SIGTTIN, or SIGTTOU signal or if it receives any signal while it is being debugged.

Journalize Crystal Clear\'s declaration of the stock dividend on July 15 and distribution on July 31. What is the overall effect of the stock dividend on Crystal Clear\'s total assets? What is the overall effect on total stockholder\'s equity?
Solution
Date Account heads Debit Credit 15-Jul To record declaration of stock dividend Retained earnings (14000 * 10% = 1400 * $20) 28000 Stock dividend distributable (1400 * 1) 1400 Paid in Capital in excess of par (1400 * 19) 26600 31-Jul To record distribution of stock dividend Stock dividend distributable (1400 * 1) 1400 Common stock account 1400 2. Unlike cash dividend, stock dividend involves no distribution of assets or liabilities. So, it has no effect on the Assets or Liabilities 3. Stockholders\' equity, also called owners\' equity, is the surplus of a company\'s assets over its liabilities. Cash dividends reduce stockholders\' equity by distributing excess cash to shareholders. Stock dividends distribute additional shares to shareholders and do not affect the balance of stockholders\' equity. Net worth (Share capital + retained earnings) is not affected. It is an inter change of Numbers between the two. Equity capital balance is increased and retained earnings balance is reduced

Critical thinking question- what structural features (hint- there are.docx
Critical thinking question: what structural features (hint: there are four) do all ten of these opioid drugs have in common?
Opioids Opioids are a powerful class of alkaloids that act on the central nervous narcotic analgesics. All opioids presumably bind to the same mu-opioid receptor sites in the brain and spinal cord. The most prevalent naturally occurring isolated from the opium poppy-is morphine (named after Morpheus, the sod of dreams). A methoxy derivative of morphine that is also isolated from opium poppy is codeine, which is both less addictive and less effective as a reliever than morphine. By contrast, the diacetyl derivative of morphine (heroin) isanalgesic not only a more powerful as a narcotic but also more addictive than morphine Many other synthetic derivatives of morphine are opioid agonists that are used as narcotic analgesics (including oxycodone, oxymorphone, hyd system as a plant-derived nitrogenout bases that have pronounced physiologial acevity on humans the arcotic a drug dhas numbs the ngonisa molecule that combines antagonist a molecule that inhibits senses and induces stupor a druE hat with a receptor to initiate and meperidine), while others (such as methadone and buprenorphine) are used to treat opioid addiction.

Create a polynomial function that meets the following conditions- Expl.docx
Create a polynomial function that meets the following conditions. Explain how you created your polynomial.
4. Degree 3, 2 positive real zeros, 1 negative real zero, 0 complex zeros.
Polynomial:
Solution
Polynomial may be : f(x) = -x^3 + x^2 + x - 1 Reasoning : the number of positive roots of the polynomial is either equal to the number of sign differences between consecutive nonzero coefficients. so here has two sign change(the sequence of pairs of successive signs is -+, ++, +-). So it has 2 positive roots. for negative root we change the signs of the coefficients of the terms with odd exponents, i.e., apply Descartes\' rule of signs to the polynomial f(-x), to obtain a second polynomial f(-x) = x^3 + x^2 - x - 1 it has 1 sign change so f(-x) has one positive root so f(x) has 1 negative root.

Since you have not specified structure of IntNode class,so I am assuming that structure of IntNode:
class IntNode{
int data;
IntNode next;
//other methods and constructors
}
public static void LinkedListSearch(IntNode head, int key){
while(head != null){
if(head.data == key){ // if found, then print message and return
System.out.println(key+\" is founded!!\");
return;

Create a function called findChar that will return the index of where.docx
Create a function called findChar that will return the index of where a particular character is found within a CString.
Your function should take as parameters the CString to search through and a character variable to search for.
The function will return the index of where the character was first found.
If the array does not have the character in it, your function should return -1.
NOTE: Do not convert or cast the characters to int\'s to do the searching. At this point you should be able to traverse a CString.
Solution
import java.util.Scanner;
import java.io.*;
import java.lang.*;
public class FindingIndex{
public static void main(String args[]){
String [] Cstring = new String [10];
System.out.println(\"Please enter the string \");
System.out.println(\"Character to search\");
Scanner in = new Scanner(System.in);
Cstring = in.nextLine();
char c = in.nextChar();
CstringIndex(Cstring,c);
}
public static int CstringIndex(String[] Cstring2,char newchar){
for(int i=0;i<Cstring2.length();i++)
{
if(c == Cstring2[i])
{
System.out.println(\"Index of the character \"+i);
break;
}
else
{
System.out.println(\"-1\");
}
}

Could someone help me with this Linux system program- Using C language.docx
Could someone help me with this Linux system program. Using C language.
Write your own simple client/server set of processes. The client should use a shared memory segment to send a command message to the server. The server process should monitor the shared memory segment, and respond as follows:
\"HI\" -- The server prints \"Greetings\" to the screen.
\"PID\" -- The server prints it\'s process id to the screen.
\"QUIT\" -- The server terminates gracefully, detaching and releasing the shared memory segment.
Sample run:
Client :
Server:
HI PID QUIT

Contrast the argument that terrorist acts are easy to predict with the.docx
Contrast the argument that terrorist acts are easy to predict with the argument that they cannot be identified or predicted. Write it 4-5 paragraph with resources(References).
Solution
By using technology it was easy to predict the terrorist acts. This is because terrorists use social media sites for communication and now-a-days there are many pattern recognization and data mining algorithms are implemented to identify the words and to predict the next action of the terrorists
reference:http://www.iflscience.com/technology/how-technology-help-predict-terrorist-attacks/
And even though advancement of technology cannot predict the terrorist act all the time, because if the terrorists are at one place then they don\'t use the internet or social media sites, so there will be no chance of prediction.
But NSA, which have access to almost every device in the world can easily predict the action of every human being in the world and there are many other security agencies like NSA also can do this thing. Majorly, technology plays an important role in identifying or predicting the action of terrorists

contemporary financial management What are the differences between the primary and secondary markets?
Solution
The difference between the primary capital market and the secondary capital market is that in the primary market, investors buy securities directly from the company issuing them, while in the secondary market, investors trade securities among themselves, and the company with the security being traded does not participate in the transaction.

Constants Part A By measurement you determine that sound waves are spr.docx
Constants Part A By measurement you determine that sound waves are spreading out equally in all directions from a point source and that the intensity is 2.7x10-2 W/m2 at a distance of 4.5 Im from the source What is the intensity at a distance of 3.5 m from the source? Express your answer using two significant figures W/m2 Submit Incorrect. Try Again; 6 attempts remaining Part B How much sound energy does the source emit in one hour if its power output remains constant? Express your answer using two significant figures Submit
Solution
Part A.
Intensity is given by:
I = P/A = P/(4*pi*r^2)
Since Source is same at both distance, So Power is constant, which means intensity is inversely proportional to square of distance from source.
I2/I1 = (r1/r2)^2
I2 = I1*(r1/r2)^2
I2 = 2.7*10^-2*(4.5/3.5)^2
I2 = 4.5*10^-2 W/m^2
Part B.
Power of source will be
P = I*4*pi*r^2
P = 2.7*10^-2*4*pi*4.5^2
P = 6.87 W
Now energy is given by:
E = Power*time
E = P*t
t = 1 hr = 3600 sec
E = 6.87*3600
E = 24732 J = 2.5*10^4 J

http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
