2.52.There is a whistle attached to each end of a 3.4m long stick. As shown in the picture on the right, the bar rotates at an angular speed of 20 rad/s in the horizontal plane with the line passing through the center of the bar as the axis. What is the maximum number of beats per second observed by a person far away from this bar? (However, the vibration frequency of the sound coming from the whistle is 99Hz, and the speed of sound is 340m/s.) N=rw=34m/ дан 20 rows/s w = 20 rad/s
