Answer:
437.5 watts.
Explanation:
One watt power (1-watt) is used to describe the situation of an electrical appliance where 1 joule of energy per seconds of time (1 J/s) is consumed or used.
According to the information in the question, a man can lift a load of 175N (Force) to a height of 25 m (distance) in 10 seconds (time).
Power = Workdone (J) ÷ time (s)
Workdone = Force (N) × distance (m)
Workdone = 175 × 25
Workdone (W) = 4375J
Power = W/t
P = 4375/10
P = 437.5 watts.
