Question

a. define the law of conservation of energy.
b. as water descends from the to of a hydroelectric dam, its gravitation potential energy is converted into electric energy.

how much gravitational potential energy is released when 1500 kg of water descends 20 m to the generators? How much of kinetic energy will be available with the water during it descend?

Answer 1

a) it states that energy can neither be created or destroyed but can only be transformed from one into another or transferred from one object to another

Answer 2

a . law of consevation of energy states that energy can neither be craeted nor destroyed but can be changed from one form to other.

Sorry question i dont no "Sorry"
