a waterfall is 30 m high and 10000 kg of water flow over it every second
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
