Question

1000 joules of energy are put into a pulley system, and 400 joules come out. What does the Law of Conservation of Energy imply about the lost

energy? (1 point)
O The lost energy cannot be recovered.
O The lost energy is not truly lost, but it changed into a different form.
O The lost energy is caused by friction.
O The pulley system could be improved to conserve some of the lost energy.

Answer 1

The answer I B

Step-by-step explanation:

The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside.
