Question

Study the scenario.

Answer 1

Answer:

Option (C)

Explanation:

According to the law of conservation of energy, energy can neither be created nor be destroyed. it can transform from one form to another.

For example, in case of electric bulb, the electrical energy is converted into light energy.

The energy of toy when it is moving is 150 J. It means the energy stored in the system before the launch of toy is also 150 J. It is assumed that there is no loss of energy in another forms.

Answer 2

(C)150 J, because the initial and final energy must be the same in an isolated system

Oh yea.. the Law of Conservation of energy states that energy stays the same throughout a system XD  bet
