What happens when electrical energy is used to power stereo speakers?

A. Energy is neither lost nor gained as electrical energy is transformed into the energy of sound.
B. Energy is gained as electrical energy transforms into the energy of sound.
C. Energy is lost as electrical energy transforms into the energy of sound.
D. Energy is neither lost nor gained as sound energy transforms into electrical energy.

Law of conservation of energy states that energy can neither be lost nor created but can be transformed from one form to another. When powering a stereo speaker, electrical energy is transmitted through wires and is then converted to sound energy in the stereo speaker. Therefore, A. energy is neither lost or gained as electrical energy is transformed into the energy of sound.

When stereo speakers are powered by electrical energy, that energy transforms into sound energy through speaker vibrations. According to the law of conservation of energy, the total energy is conserved, meaning energy is neither created nor destroyed during this process. Therefore, the correct choice is A: Energy is neither lost nor gained as electrical energy is transformed into the energy of sound.
