Acarnot heat engine operates between 1000 k and 300 k (atmospheric temperature) and uses the net work output to drive a refrigerator, also working on a carnot (ideal reversible refrigeration) cycle. the refrigerator maintains the cold space at 240 k. if the heat input to the carnot heat engine is 100 kw, determine the cooling capacity (heat removed from the cold space) of the refrigerator in kw

answer: i have no clue tbh

explanation:

it happens to me to tho

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
