Question

A table is rotating about its axis with an angular speed of 5 rev/sec. A source of sound of
frequency 600 Hz is fixed on the table at a distance of 0.7 m from the axis. The maximum
frequency heard by a listener at rest at a certain distance from the table is (v = 352 m/s)​

Answer 1

Answer:

470.58

Explanation:

vs=rw=0.7×2pi×5=22m/s

Nmin =N (v/v+vs)

=500(352/352+22)

=470.58
