A source S of acoustic wave of frequencyv_(0) = 1700Hz and a recelverR are located at the same point . At the instant t = 0 , the source starts from rest to move away from the receiver with a constant acceleration omega. The velocity of sound in air is v = 340 ms^(-1) .Ifomega = 10 m * s^(-2) , the apparent frequency that will be recorded by the stationary receiver just at the Instant when the source is exactly 1 km away from the receiver will be .
