Question

question 1
why do we hear sound?
○ because of disturbed/moving air molecules
○ because of gravity
○ because i ate a sandwich

Explanation:

Sound is a type of mechanical wave that requires a medium (like air) to travel. When an object vibrates, it disturbs the surrounding air molecules, creating a series of compressions and rarefactions (longitudinal waves) that travel through the air. These waves reach our ears and cause the eardrum to vibrate, which is then processed as sound. Gravity is a force related to the attraction between masses and has no direct relation to the perception of sound. Eating a sandwich is unrelated to the physical process of hearing sound.

Answer:

A. Because of disturbed/moving air molecules
