Two tuning forks with natural frequencies of `340 Hz` each move relative to a stationary observer. One fork moves away form the observer, while the other moves towards him at the same speed. The observer hears beats of frequency `3 Hz`. Find the speed of the tuning fork.

Two tuning forks with natural freque. ncies 340 Hz each move relative to a stationary observer. One fork moves away from the observer, while the other moves towards him at the same speed. The observer hears beats of frequency 3 Hz. Find the speed of the tuning fork. (Velocity of sound in air = 340 in/s)

The observer hears beats of frequency 3 H_(Z) . Find the speed the of the tuning fork (velocity of sound in air is 340 m//s) .

Two tuning forks with natural frequencies 340 H_(Z) each move relative to a stationary observer . One forks moves away from the oberver while the other moves towards him at the same speed . The observer hearts beats of frequency 3 H_(Z) . Find the speed the of the tuning fork (velocity of sound in air is 340 m//s) .

Two tuning forks A and B lying on opposite sides of observer 'O' and of natural frequency 80 Hz move with velocity 10 m//s relative to stationary observer O . Fork A moves away from the observer while the fork B moves towards him. A wind with a speed 10 m//s is blowing in the direction of motion of fork A . Find the beat frequency measured by the observer in Hz. [Take speed of sound in air as 340 m//s ].
