300K and 95kPa (State 1). The air is compressed in the engine to an unknown pressure. Heat is then added during combustion at an amount of 1100 kJ/kg. At the end of the heat addition process, the temperature reaches 2200K. Compute the following: (a) the temperature at the end of the compression process, (b) the volumetric compression ratio of this engine, (c) the amount of work done during the compression process per kg of air, (d) the temperature at the end of the expansion process, (e) the net work of the cycle per kg of air, and (f) the cycle thermal efficiency. Assume air to be an ideal gas with constant specific heats [Cp, o

answer:

what happend?

explanation:

answer:

i am not 100% sure but i think it is a.)

dont take my word for it

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
