Apiston-cylinder assembly contains 0.15 kg of air at a temperature of 350°c and a pressure of 2 mpa, undergoes three reversible processes in series process 1-2: the air is expanded isothermally until the pressure is 500 kpa process 2-3: the air is compressed polytropically with a polytropic index of 1.2 back to 2mpa. process 3-1: the air is compressed at constant pressure to the initial state given for air: r = 0.287 kj/kgk. a)- sketch the processes on a p-v diagram. b. i)- the volume of air in the system at the initial state and at the end of each process. ii)- the boundary work at the end of each process.

answer:

located where wight collar workers are

explanation:

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
