Power=work/time
Work(in this case)=mgh(work done=energy consumed)
Because we need to raise the water
So power=mgh/t
Power=100*10*19/25
Power=760W
Any other?

Answer: 760 watts
Explanation:m = 100kg
g=10m/s2
h=19m
t=25sec
Work done= mgh
=100x10x19
= 19000joules
Power=work done/time taken
=19000/25
=760 watts
