How much work is done using a 500 w microwave for 5 minutes

Explanation:

The power used by an object is defined as:

where

W is the amount of work done by the object

t is the time taken

In this problem, we have:

P = 500 W is the power of the microwave

is the time taken

So we can solve the formula for W, the work done by the microwave:

c)as speed changes, wavelength and frequency change.

everything changes!
