Water flows over Niagara Falls at the average rate of 2,400,000 kg/s, it mean it is mass per unit time i.e. m/t.
It falls from a height of 50 m
The gravitational potential energy of falling water is given by :
P = mgh
Power is equal to the work done divided by time taken. So,
So,
Let there are n bulbs that could power 15 W LED. It can be calculated by dividing the power by 15. So,
It means that the number of bulbs are 78400000.
