Question

as a student releases a stretched rubber band, which of the following energy transformations occurs?
a potential to kinetic
b electrical to sound
c chemical to electrical
d chemical to thermal

Explanation:

A stretched rubber band has elastic potential energy. When released, it moves, converting that potential energy into kinetic energy (energy of motion). Option b involves electrical energy (not present here), option c involves chemical to electrical (no chemical energy conversion here), and option d involves chemical to thermal (also not applicable here). So the correct transformation is potential to kinetic.

Answer:

a. potential to kinetic
