Assertion : A sound source is approaching towards a stationary observer along the tine joining them. Then , apparent frequency to the observer will go on increasing. Reason : If there is no relative motion between source and observer , apparent frequency is equal to the actual frequency.

A long belt is moving horizontally with a speed of 5 km/h. A child is running on belt to and fro with a speed of 9 km/h with respect to belt between his father and mother located 50 m apart on the belt. For an observer on a stationary platform outside, what is the speed of the child running opposite to the direction of the belt ?
