Mark the correct statement(s) (1) If speed of a body is varying, its velocity must be varying and it must have non-zero acceleration.
(2) If velocity of a body is varying, its speed must be varying.
(3) A body moving with varying velocity may have constant speed.
(4) A body moving with varying speed may have constant velocity, if its direction of motion remains constant.
