A0.05-m3 rigid tank initially contains refrigerant- 134a at 0.8 mpa and 100 percent quality. the tank is con- nected by a valve to a supply line that carries refrigerant-134a at 1.2 mpa and 40°c. now the valve is opened, and the refrig- erant is allowed to enter the tank. the valve is closed when it is observed that the tank contains saturated liquid at 1.2 mpa. determine (a) the mass of the refrigerant that has entered the tank and (b) the amount of heat transfer.

answer: jesus loves you

explanation:

answer: Yes

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
