Question

Pls answer this question I will give him as brainliest and thanks and stars

Answer 1

Loudness depends on amplitude of the vibrating body so when amplitude increases loudness also increases. pitch depends on frequency of the vibrating body so when frequency increases pitch also increases. (a) Loudness of sounddepends upon the amplitude of vibration of vibrating object.

Loudness of sound depends upon the amplitude of vibration of vibratingobject. ... (b) The pitch of a sound depends upon the frequency of the vibrating body, As the frequency of vibration becomes higher, the pitch also increasesand the sound becomes more shrill .

Answer 2

5- light travels faster than sound.
6-a-loudness-the respond of ear to sound.
6- b-pitch - the frequency by which brain interprets a sound.
6b-1-loudness will also increase
6b2-pitch will increase. sound will become more shrill.
7-noise pollution can cause loss of hearing, distraction in studies, may also cause death.

hope it helps
