Calculate the charge developed on a vessel being filled with carbon black by pouring from another open vessel. Assume the vessel has a volume of 1.89 m^3 and the feed rate is 0.1 kg/s. Identify the accumulated charge and the energy, and then determine whether the energy exceeds the MIE of dusts. Does the lower charge rate loweres the potential hazard?

answer:

1.3 + 20

explanation:

20.1.3

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
