Question

In a cinema theatre electrical energy is transformed into ____________and_______________ energy. Fill in the blank.

Answer 1

Light energy and heat energy

Answer 2

Answer:

Light energy and sound energy.

Explanation:

According to the conservation law of energy we came to know that we cannot produce or destroy energy.

We can just modify the energy into one form to another form.

Similarly,the electrical energy is transformed into light energy (a little amount of heat energy is also produced but that is negligible)by the projector and into sound energy by the speakers.
