The purification of hydrogen gas is possible by diffusion through a thin palladium sheet. Calculate the number of kilograms of hydrogen that pass per hour through a 5.5-mm-thick sheet of palladium having an area of 0.45 m2 at 500°C. Assume a diffusion coefficient of 5.0 × 10-8 m2/s, that the concentrations at the high- and low-pressure sides of the plates are 2.3 and 0.43 kg/m3 of hydrogen per cubic meter of palladium, and that steady-state conditions have been attained.

ikr

but i think it's when 2 couples kiss and they rlly love eachother so much and there kiss is slowly idk what i'm sayingxd

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
