A student holds a tuning fork oscillating at 256 Hz. He walks toward a wall at a constant speed of 1.09 m/s.(Solve this without calculus) (a) What beat frequency does he observe between the tuning fork and its echo?  Hz (b) How fast must he walk away from the wall to observe a beat frequency of 4.90 Hz?  m/s

A student holds a tuning fork oscillating at 256 Hz. He walks toward a wall at a constant speed of 1.45 m/s. (a) What beat frequency does he observe between the tuning fork and its echo? 0.08 x Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. Hz (b) How fast must he walk away from the wall to observe a beat frequency of 5.60 Hz? 5.60 X Your response differs from the correct answer by more than 10%. Double check your calculations. m/s

A Slinky stretched to 4.00 m carries a wave along its length. (a) How fast does the wave propagate if it takes 2.4 s to travel down the Slinky and back again? (b) In the same Slinky, a standing wave with four nodes and three antinodes is set vibrating. What is the frequency of vibrations?

To drive a spring with k = 120 and a mass of 3 kg (attached) in resonance at what frequency should the energy be applied? 4 Hz 1 Hz 2 Hz 2 Hz

Vibration of the dishwasher causes standing waves in a cup. Crests form four concentric rings, and the diameter of the cup is 6.0cm. v=1.5m/x. What is the frequency of the vibrations?

Question 12 12. A string of length 0.58 m is producing a standing wave of period 7 second with 9 harmonics. The speed (m/s) of the wave of the string is:

The frequency of middle C is 256 Hz and its wavelength is 1.33 m in air at roomtemperature. If a student plays this key on the piano, at what speed does the vibrationtravel?

Two tuning forks A and B when vibrated together, produce 4 beats per second. Frequency of A is 480 Hz. After B is filed and the two forks are again vibrated together, beat frequency is generated again as 4 per second. What would be the original frequency of B? [Hint : Frequency of B should increase after filing, so beat should increase as well after filing] 470 Hz 500 Hz O 476 Hz 480 Hz

There is a long steel wire of length 2.7 m where its upper end is attached to the ceiling. At the other end, a 56.2 kg object is suspended. It is observed that it takes a transverse pulse 0.0345 s to travel from the bottom to the top of the wire. What is the mass of the wire? NOTE: Final answer in THREE decimal places. Include the unit. Round your answer to 3 decimal places.
