When an object is moving away from you while making a sound the pitch of the sound is perceived to be?

Answer;

The pitch is lower

Explanation;When an object is moving away from you while making a sound the pitch of the sound is perceived to be lower.This phenomenon is described as the Doppler effect. Doppler effect explains the change in the observed frequency of a wave when there is a relative motion between the wave source and the observer.The pitch perceived by an observer depends on the frequency of the sound wave. A high frequency corresponds to a high pitch. when a  body such as an ambulance siren, or police car siren is moving away from the observer, the frequency observed and the pitch of the sound drop.

Ifound this on google “two vectors are equal if they have the same magnitude and direction. they are parallel if they have the same or opposite direction. we can combine vectors by adding them, the sum of two vectors is called the resultant.” i hope this you.
