Question

Do 120 Joules of work in 2 minute, and your power output is a. 120 Watts. b. 2 Watts. c. 240 Watts. d. 1 Watt.

Answer 1

Answer #1

Power = Energy/Time
where Power is measured in Watts, Energy in Joules and Time in Seconds

2 minutes = 120 seconds.
So, for the above question,

P = E/t

so P = 120/120

= 1W
