A. maxwell’s equations are a set of 4 equations that describe the rule of electromagnetics. write down the 4 equations and try to explain in your own words the physical insights behind each of them. (b) in addition to the 4 maxwell’s equations, there is another equation that relates the variations of the current density and the charge density this equation is referred to as the continuity equation because it relates the net flow of current out of a small volume to the rate of decrease of charge. it takes the form: ∇ ∙ = − / derive the continuity equation from maxwell’s equation. (try start by taking divergence on both sides of the modified ampere’s law and substituting with gauss’s law.) (c) for the special case of electrostatics (time invariant), try to derive the poisson’s equation ∇ = − / from the maxwell’s equations.

2. determine the proper pump operating conditions and bit nozzle sizes for - chegg

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
