Two sources of sound S1 and s2 are moving towards and away from a stationery observer with same speed respectively . Observer detects 3 beats per second. Find speed of sources (approximately) .
Given, F1=F2=500 Hz, speed of air = 330 m/s

Consider two tuning forks with natural frequency 250 Hz. One is moving away and another is moving towards a stationary observer at same speed. If the observer hears beats of frequency 5 Hz, then the speed of the tuning fork is : ( Given, speed of sound wave is 350 m/s . )

a bus is moving towards and stationary observer with speed 20 m/s blows a horn of frequency 200 Hz. the frequency of sound heard by the observer is approximately ( take speed of sound 320 m/s)

A source of sound of frequency n is moving towards a stationary observer with a speed S. If the speed of sound in air is V and the frequency heard by the observer is n_(1) ,the value of n_(1)//n is

When a source moves away from a stationary observer, the frequency is (6)/(7) times the original frequency. Given: speed of sound =330(m)/(s) . The speed of the source is

When a source moves away from a stationary observer, the frequency is (6)/(7) times the original frequency. Given: speed of sound =330(m)/(s) . The speed of the source is

A source of sound of frequency 500 Hz is moving towards an observer with velocity 30 m/s.The speed of the sound id 330 m/s.The frequency heard by the observer is
