Question

part a according to the law of conservation of energy, energy is not created or destroyed. it changes form or is transformed. what energy transformation(s) is/are depicted here? a electrical energy → light energy b potential energy → kinetic energy → light energy c chemical energy → electrical energy → light energy d chemical energy → electrical energy → heat and light energy electrical energy 750 j generator kinetic energy 400 j ?

Explanation:

In a typical electrical - generating setup, chemical energy in a battery (for example) can be converted to electrical energy. When this electrical energy powers a light - emitting device, some of it is converted to light energy and also heat energy due to inefficiencies. The diagram shows electrical energy going into a generator and kinetic energy coming out, but considering the general context of energy conversions in electrical systems that produce light, chemical energy can first be converted to electrical energy which then is converted to heat and light energy.

Answer:

D. chemical energy → electrical energy → heat and light energy
