Question

at a constant speed, a source of sound approaces, passes, and moves away from a stationary listener. The pitch of the sound heard by the listener

*gradually becomes higher

*is constant as the source approaches the listener, rises abruptly as the source passes and remains constant but higher as the source moves away.

*gradually becomes

*is constant as the source approaches the listener drops abruptly as the source passes and remainds constant but lower as the source moves away
