Two vibrating tuning forks have identical frequencies, but one is stationary and the other is mounted at the rim of a rotating platform. What does a listener hear? Explain.
Homework Answers
The listener would hear beats that come and go. When the moving tuning fork is moving across the line of sight (or hearing), there would be no beats. When it’s moving toward, its pitch would be too high, and beats would be heard. Similarly when moving away

Tuning fork 1 Tuning fork 2 Bob 9.0 m - 3.0m - Two identical tuning forks are positioned 9.0 m apart, and emit sound equally in all directions. Alex is standing exactly halfway between the tuning forks, and Bob is standing 3.0 m to the right of the rightmost tuning fork. Alex hears an intensity of one tuning fork of 55 dB playing at 300 Hz. 1. How much power is emitted as sound by one tuning fork? 2. When...

The answer is B
15, Two identical tuning forks vibrate at 413 Hz. A small piece of clay is placed on one of tuning forks resulting in ten beats per second being heard. Calculate the period of the altered tuning fork a) 2.42 X 10-3s b) 2.48 X 10 s c) 2.54 X 10's d) 2.60 X 10s e) 2.36 X 103

You have 2 tuning forks in your hands; one plays the note D (297 Hz) and the other plays the note A (220 Hz). Your classmate plays a third fork with an unknown note and listens to the new combined frequency. Assuming that you can measure the combined frequency like 275 Hz when all three forks are played simultaneously, which of the following notes is most likely to correspond to the mysterious tuning fork a. C (264 Hz) b. F...

Two train whistles have identical frequencies of 1.62 x 10 Hz. When one train is at rest in the station and the other is moving nearby, a commuter standing on the station platform hears beats with a frequency of 8.00 beats/s when the whistles operate together. What are the two possible speeds that the moving train can have? m/s moving away from the station m/s moving towards the station

Two identical 375-g speakers are mounted on parallel springs, each having a spring constant of 50.0 N/cm. Both speakers face in the same direction and produce a steady tone of 1.00 kHz. Both sounds have an amplitude of 35.0 cm, but they oscillate 180° out of phase with each other. What is the highest frequency of the beat that a person will hear if she stands in front of the speakers?

Two identical motor bikes are racing towards each other, each at 50 m/sec. Each bike has a horn that is sounding a very low frequency signal of 22 hertz. What does each biker hear upon approach? What does each biker hear after they have passed each other (receding)? Explain and discuss. Assume the speed of sound in air is 350 m/s. In what season did this event probably take place if it was in Toledo? Explain.
