a waterfall is 30 m high and 10000 kg of water flow over it every second(adsbygoogle = window.adsbygoogle || []).push({});

A) calculate the potential energy

PE = mgh

got 2.94E6 joules

B) calculate the power delevered by the water of all the potential energy is converted to work

F = mA

F= 10000 * 9.80

f = 98000

w = Fm

w 98000 * 10000

w = 980 MJ mega joules

C)If all the power were converted to electricity, how many 100watt light bulbs could be lit

not even sure on how to approach this
