Question

From a dam, water is pouring down at the rate of 150 kg/s, on the blades of a turbine. If a ball dropped from the same dam takes 2√5 s to hit the turbine, then the power delivered to the turbine is approximately equal to (Take g = 10 m/s²)

Answer 1

From the given question we can say that the power is here to be find
And N=dalta mgh
we don't know about the height so in order to find height formulla is 
h = gt²/2 = 10*(  2√5)²/2              as we know g= 10 and time = 2√5

so height = 100 meter 
and
N=Δmgh 
by putting the values in the equation 
 N= 150*10*100 = 1.5 * 10^5 W
So the power will be 1.5*10^5 W.

Answer 2

Answer:

the answer is 1.5*10 power 5 w.
