We plan on using thermal evaporation chamber to grow a metal alloy (thin film) with Cu 2.0 wt% (weight percent) and Al 98.0 wt%. Source temperature is controlled at 1350K. Please estimate what the target concentrations (weight percent) are in order to maintain the right alloy composition. (Vapor pressure for Al at 1350K is 10-3 torr, and for Cu at 1350K is 2x10-4 torr. Note that if we change the source temperature for growing this alloy, the target concentration needs an adjustment based on their vapor pressure variations.)

how is this a question? in order for me to answer it i have to understand the question

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
