What type of energy can we hear?

Sound energy is the correct answer because it is the type of energy that travels through a medium, such as air, water, or solids, and can be detected by our ears. Sound is produced when objects vibrate, creating pressure waves in the surrounding medium. These waves stimulate the auditory system when they reach our ears, allowing us to perceive sound.

Thermal energy, while it can influence sound in terms of how sound waves travel through different temperatures, is not something we can hear. Similarly, electrical energy refers to energy derived from electric potential or current and is not related to sound perception. Nuclear energy, on the other hand, involves energy released during nuclear reactions and does not pertain to sound waves at all. Sound energy specifically pertains to the vibrations and waves that are audible, making it the only relevant option in this context.
