Question: A girl lifts a 160-N load to a height of 1m in 0.5s. How much power is used to lift the load? Answer: 320W

Explanation:

Power is the energy consumed to do work in unit time. It is calculated by dividing the work done with the time it took for the work to be done.

It is expressed as:

Power = Work / Time = Force x Distance / Time

Given that the force is 160 N, distance is 1 m, and time is 0.5 s, we can calculate the power:

Power = 160 N (1 m) / 0.5 s = 320 W

Therefore, the correct answer is the third option, which is 320W.

Hope this answers the question. Have a nice day.
