    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.
