girl lifts a 160-N load to a height of 1m in 0.5s.

how much power is used to lift the load?

32w

160w

320w

80w

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

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

Therefore, the correct answer is the third option.

Hope this answers the question. Have a nice day.
