d. What is one watt power? Calculate the power of
a man if he can lift a load of 175 N to a height of
25 m in 10 second (1+2)​


Sagot :

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.
