Ernie · Answer 1

Watt is a unit for power that is also equal to J/s. We therefore need to convert the minutes to seconds first before answering. Every minute is comprised of 60 seconds. Therefore, 3 minutes are composed of 180 seconds. Multiplying the number of seconds to the given power will give us,

Work = Power x time

= (1500 J/s) x (180 s)

= 270,000 J

Therefore, the answer is letter D.
