Question

how is sound produced by striking a tuning fork or other activities like plucking and scratching? choose 1 answer: a by creating electrical signals b by manipulating gravitational waves c by setting objects vibrating d by generating light waves

Explanation:

Sound is produced when an object vibrates. When a tuning - fork is struck or an object is plucked/ scratched, the object starts vibrating. These vibrations create pressure waves in the medium (usually air) which we perceive as sound. Electrical signals are related to electronics and not the basic production of sound by mechanical means. Gravitational waves are related to massive cosmic events and have nothing to do with the production of sound by everyday objects. Light waves are a different form of electromagnetic radiation and not related to sound production.

Answer:

C. By setting objects vibrating
