Answer:

$1.5\cdot 10^5 J$

Step-by-step explanation:

The power used by an object is defined as:

P=(W)/(t)

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

t=5 min=300 s is the time taken

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

$W=Pt=(500 W)(300 s)=1.5\cdot 10^5 J$
