1.	A small source of sound vibrating at frequenc 500 Hz is rotated in a circle of radius (100//pi)cmat a constant angular speed of 5.0 revolutions per second . The speed of sound in air is 330 m .s^(-1) . An observer (A) is situated at a great distance on a straight lineperpendicular to the plane of the circle , through its centre . Another observer (B) is at rest at a great distance from the centre of the circle byt nearly in the same plane . After something the source of sound comes to rest after reaching the centre of the circle . At that time , another observer (C) moves towards the source with a constant speed of 20 m .s^(-1) , along the radial line to the centreThe apparent frequency of the source heard by A will be
