The beat detected on a moving platform.
A speaker fixed to a moving platform moves toward a wall,
emitting a steady sound with a frequency of 230 Hz . A person on
the platform right next to the speaker detects the sound waves
reflected off the wall and those emitted by the speaker.
Part A.) How fast should the platform move, vp, for the
person to detect a beat frequency of 2.00 Hz? Take the speed of
sound to be...

4. In a large lecture hall, the professor uses a microphone and her voice is amplified over two speakers located at the front of the fall in the upper right and left corners. The speakers are separated by a distance of D-15 meters. You pick a spot in the hall that is located Si-13.0 meters from the right speaker and S 12.5 meters from the left speaker. Assume the speed of sound is 343 m/s. Assuming the speakers are connected...
