Water flows over Niagara Falls at the average rate of 2,400,000 kg/s, and the average height of the falls is about 50 m. Knowing that the gravitational potential energy of falling water per second = mass (kg) Ă— height (m) Ă— gravity (9.8 m/s2), what is the power of Niagara Falls? How many 15 W LED light bulbs could it power?
