Answer 1

Answer:

i can give short answer not brief.

Explanation:

it is due to the doppler effect. The Doppler effect is a change in the frequency of sound waves that occurs when the source of the sound waves is moving relative to a stationary listener. As the source of sound waves approaches a listener, the sound waves get closer together, increasing their frequency and the pitch of the sound.
