1.

The power rating of anelectric lawn mower is 2000watts. If the lawn mower isused for 120 seconds, how manyjoules of work can it do?

Answer»

WORK DONE = 240000Joules = 240 KiloJoules

Explanation:

$power \: = \frac{work \: done}{time}$

$work \: done \: = power \times time$

$work \: done = 2000 \times 120$

$work \: done = 240000 \: joules = 240 \: kilojoules$
