Question

How much work can be done in 30 seconds by a 1000-watt microwave oven?

Answer 1

30000 J

Explanation: i just needed the points :/

Answer 2

30000 J

Step-by-step explanation:

Power is defined as the amount of work done per unit time:

`P=(W)/(t)`

where

P is the power

W is the work done

t is the time taken

In this problem, we know the power of the microwave oven:
`P=1000 W`, and we are asked to find the work done in a time of
`t=30 s`, so by re-arranging the equation we find:

`W=Pt=(1000 W)(30 s)=30,000 J=30 kJ`
