Apower cycle operating at steady state receives energy by heat transfer at a rate qh at th = 1000 k and rejects energy by heat transfer to a cold reservoir at a rate qc at tc = 300 k. for each of the following cases, determine whether the cycle operates reversibly, operates irreversibly, is impossible. qh = 500kw, qc = 100kw qh = 500 kw , wcycle = 250 kw, qc = 200 kw wcycle = 350kw, qc = 150kw qh = 500kw, qc = 200kw

explanation:

answer: copyright is extremely important to authors because it constitutes the ownership of one's original work. having ownership means you can protect your work as intellectual property and control who makes money from it—which is you and those to whom you assign rights.

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
