Question

The power rating of an
electric lawn mower is 2000
watts. If the lawn mower is
used for 120 seconds, how many
joules of work can it do?​

Answer 1

Answer:

Work done = 240000Joules = 240 KiloJoules

Explanation:

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

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

$work \: done = 2000 \times 120$

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