Answer:
100 Watts
Explanation:
- Power is the rate at which work is done.
- Power is measured in Joules per second or watts.
- It is calculated by dividing work done in joule by time taken in seconds.
Power = Work done ÷ time
In this case;
Work done = 10,000 Joules
Time = 100 sec
Therefore;
Power = 10,000 Joules ÷ 100 sec
= 100 J/s
Therefore, the power of the crane is 100 watts
