As shown in the figure two sources producing sound Sr and Sn (velocity of sound 360 m/sec) each producing sound of frequency 200 Hz. S_(1)is rotating anti clock wise where as S_n is approaching observer O each with a speed 10 m/sec. (neglect radius of circular path of S_1), then calculate If wind is blowing from right to left with a speed 10 m/sec and observer is at rest find the number of beats received by observer when S_(1)is at A.
