Question

How do you determine the constant of proportionality if E is inversely proportional to z and z=4 when E=6?

Answer 1

`24`

Explanation:

If `E` is inversely proportional to `z` by some constant `k`, then we have the equation:

`E=k/z`

When `E=6,z=4`, and therefore the constant of proportionality is:

`k=E*z`

`=6*4`

`=24`
