Answer 1

Answer 2

1hp= 746 watt=746 j/s
now your question is incomplete , for how much time
will the pump work? if it keeps working it will keep pumping and practically in 1s it won't do anything lol

Answer 3

P.E=m*10*10=mgh= 746, you can find m ideally

Answer 4

Power = work ÷ time, work = force × distance.
In this case, the force is the weight of the water, and the distance is the 10m height.

\(\large \rightarrow power = \frac{weight × height}{time}, P=\frac{mgh}{t}\)

\(\large \rightarrow \frac{m}{t} = \frac{P}{gh}\)
