Answer:
power generated by motor = 0.13 W
Explanation:
quantity of water lifted = V = 0.101 m³
Height h = 5 m
Time taken t = 10 min = 600 s
pump efficiency η = 60 % = 0.6
mass of water lifted m = ρ V
= 1000 x 0.101
= 1 kg
Work done W = mgh = 1 x 9.8 x 5
= 49 N m
power P = W/t η = 49/(600 x 0.6)
= 0.13 W
