Question

A 30 W engine generates 3600 J of energy. How long did it run for?

Answer 1

so the time taken will be 120 seconds

Step-by-step explanation:

power=30W

work done=3600J

time=?

as we know that

`power=(work done)/(time taken)`

evaluating the formula

power×time taken=work done

`time taken=(work done)/(power)`

`time taken=(3600J)/(30W)`

`Time taken=120seconds`

i hope this will help you :)
