Answer:
HOPE IT IS HELP YOU AND ALL THE VERY BEST
AND YOUR ANSWER IS 2500W
Explanation:
Answer
Here we have the volume of water as 50/1000 m3
after converting we get this.We know that mass=density×volume
M=1000×50/1000=50kg.
Force is equal to m×g = 50×10 =500N
Workdone=F×s=500×25=12500J
Power=work/time=12500/5=2500Watt.
Hence,power generated is 2500 W.

Given :
Mass of water = 50 kg
Height = 25m
Time = 5s
To Find :
Power of the pump.
Solution :
❖ Power is defined as the rate of work done per unit time. Therefore first of all we have to find work done by force.
- Work done is measured as the product of force and displacement.
Here force acting on the water is gravitational force which is equal to mg
➠ W = F • d
➠ W = (mg) • d
➠ W = 50 × 10 × 25
➠ W = 12500 J
♦ Power of the pump :
➙ Power = Work done / Time
➙ P = 12500 / 5
➙ P = 2500 W
