A tuning fork of frequency 380 Hz is moving towards a wall with a velocity of `4(m)/(s)` Then the number of beats heard by a stationary listener between direct and reflected sound will be (velocity of sound in air is `340(m)/(s)`)

A tuning fork of frequency 90 is sounded and moved towards an observer with a velocity of sound, the note heard by the observer

A man is running with a fork of frequency 340 Hz towards a huge wall with a velocity 2m/s, then the number of beats heard per second is (Velocity of sound in air is 342 m/s)

A tuning fork of frequency 256 h_(Z) is moving towards a well with a velocity of 5 m//s . If the speed of sound is 330 m//s , then the number of beats heard per second by a stationary observer lying between tuning fork and the well is

A tuning fork of frequency 256 h_(Z) is moving towards a well with a velocity of 5 m//s . If the speed of sound is 330 m//s , then the number of beats heard per second by a stationary observer lying between tuning fork and the well is

If vibrating tuning fork of frequency 255Hz is moving with a velocity 4ms^-1 towards the wall the number of beats heard per second is (speed of sound in air = 340ms^-1 ).

A man holding a tuning fork of frequency 90 hertz runs straight towards a stationary wall with velocity of 3.7 m/sec. The number of beats per second heard by him is (Speed of sound in air =340m/s.)

A man holding a tuning fork of frequency 90 hertz runs straight towards a stationary wall with velocity of 3.7 m/sec. The number of beats per second heard by him is (Speed of sound in air =340m/s.)

A car blowing a horn of frequency 350 Hz is moving normally towards a wall a speed of 5 m/s The beat frequency heard by a person standing between the car and wall is (speed of sound in air =350 m/s )

A car blowing a horn of frequency 350 Hz is moving normally towards a wall a speed of 5 m/s The beat frequency heard by a person standing between the car and wall is (speed of sound in air =350 m/s )
