Answer:

Frequency is expressed in Hertz, which is simply cycles per second. If a tuning fork (or anything else, for that matter) vibrates 1 time each second, it's frequency is 1 Hz. So then, if it vibrates 4280 in 20 seconds, then 4280÷20=214 cycles per second = 214 Hz.

What causes the sound to have a lower volume when used in a carpeted room​
Viefleur [7K]

Answer:

Correct answer: The carpet material is soft, non-stick and diffuse and therefore absorbs waves.

Explanation:

The room is more acoustic if the walls and ceiling and floor are made of hard and polished material that reflects sound waves well while the carpeted room absorbs sound waves so it is less acoustic. The carpet material is soft, non-stick and diffuse and therefore absorbs waves.
