Answer:
Lets take heat transfer take place from 500 K reservoir to device and from device to 300 K reservoir.
From the energy conservation we can say that
-----1
For reversible process
----2
By solving above two equation
But here sign come negative it means that
heat transfer take place from device to 500 K reservoir and from 300 K reservoir to device.
Answer:29,930 kJ
Explanation:
Given
Car starts with an initial elevation of 500 m and drives up a hill to reach a final elevation of 2000 m
Final velocity (V)=20 m/s
Energy of car increases by 100 kJ
mass of car(m)=2000 kg
Total Energy=29,430+400+100=29,930 kJ
Answer:
import java.util.Scanner;
public class CountByAnything
{
public static void main (String args[])
{
int beginning = 5;
int ending = 200;
Scanner s = new Scanner(System.in);
System.out.println("Enter the value to count by:");
int valueToCount = s.nextInt();
int counter = 0;
for(int i = beginning; i <= ending; i += valueToCount)
{
System.out.print(i + " ");
if((counter+1) % 10 == 0)
System.out.println();
counter++;
}
}
}
Explanation:
- Initialize the beginning and ending.
- Loop through the value of ending variable.
- Check if numbers per line is equal to ten and Increment the counter

Answer: N has to be lesser than or equal to 1666.
Explanation:
Cost of parts N in FPGA = $15N
Cost of parts N in gate array = $3N + $20000
Cost of parts N in standard cell = $1N + $100000
So,
15N < 3N + 20000 lets say this is equation 1
(cost of FPGA lesser than that of gate array)
Also. 15N < 1N + 100000 lets say this is equation 2
(cost of FPGA lesser than that of standardcell)
Now
From equation 1
12N < 20000
N < 1666.67
From equation 2
14N < 100000
N < 7142.85
AT the same time, Both conditions must hold true
So N <= 1666 (Since N has to be an integer)
N has to be lesser than or equal to 1666.
