A source of sound with natural frequency moves uniformly along a straight line A stationary sound detector is located at a distance of 300 m from the straight line When the source is closest to the detector it records a frequency of 3f as received from the source Find the distance in m of the source from the detector at the instant when it record natural frequency of the source If your answer is 300 where x y are reduces to nearest integers from 1 to 9 then fill value x y
