1.	A man sitting on a swing which is moving to an angle of 60^(@) from the vertical is blowing a whistle is 2.0 m from the fixed support point of the whistle sound is kept in front of the swing. The maximum frequency the sound detechor detected is :
Answer» `2.027 KHZ` `1.974 kHz` `9.74kHz` `1.011kHz` Solution :Frequency `v= 2 kHz` VELOCITY of whistle (source) `v_(s)=2m` Velocity of sound `v=332m/s` MAXIMUM frequency `v_("MAX")=((V+V_(s))/(V))v` `=((332+2)/(332))xx2` `=((334)/(332)xx2` `1.006xx2` `2.012 kHz`
