Answer 2

YOUR ANSWER !!!!

_________________________________

》Power, $P = 2 kW$

》Power,

》P =Work done (W)

》Time taken (T)$⇒W=P×T$

_________________________________

• For every minute i.e. 60 s, work done by the pump is

》$W=2×1000×60=120000 J$

_________________________________

• Now, this work done is stored in water as its potential energy. Thus,

》$mgh=120000$

》$J⇒m=1200009.8×10=1224.5 kg$

__________________________________

• Hence, 1224.5 kg of water is lifted by the pump every minute to a height of 10 m.
