1. A source moving with a speed 37 m/s, emits a sound wave with a frequency f = 377 Hz. Determine the frequency detected by a stationary observer if the speed of sound is v = 343 m/s and the source is moving towards the observer. 2.A stationary source, emits a sound wave with a frequency f = 428 Hz. Determine the frequency detected by an observer moving towards the source with a speed v = 43 m/s, if the...

lllllllllllllll esc Problem 3 A sound source is moving toward you such that the frequency you observe is 5.0% greater than the frequency at the source. Assume that you are at rest. Calculate the speed of the source in km/h. (Take the speed of sound to be 340 m/s.)
A stationary man hears a sound of frequency 447 Hz coming from a source moving towards him
A stationary man hears a sound of frequency 447 Hz coming from a source moving towards him. The frequency of sound from the source is 385 Hz. Calculate the speed of the source in units of m/s. Assume v = 340 m/s.

A sound source is moving toward a listener at a velocity of 75 m/s. the listener is moving away from the sound source at 55 m/s. What frequency will the listener hear if the source frequency is 512Hz? Take 344 m/s as the speed of sound.

A politician is standing in front of a sound source playing a 440 Hertz tone. The politician, disturbed by a large hamster, starts moving to- wards the sound source. On average, a human can perceive a difference in frequency of about 0.5%. By how many Hz does the frequency have to shift (due to the Doppler effect) for the politician to notice? How fast, in meters/second, does one have to move to perceive a Doppler shift of 0.5%. Is this...

9. The speed of sound was measured in a block of using a sound source and a detector, as shown, The source travels through the block and was detected at the opposite end. From this information, the time interval for the wave to travel the entire length of the block was measured and metal (mass density of 2.700x10 kg/m produced a sound wave that determined to be 8.14x10s seconds. i. Calculate the speed of the sound wave through the metal...

A sound source located at x=29 m produces a sound pulse with a frequency of 926 Hz which you (who are standing at the origin) note has a loudness of 64 dB. At the very moment that you hear the sound, there is an object located at x=94 m moving with a velocity of 52 m/s. This object reflects the sound back to you. What is the frequency and loudness of the reflected sound when the echo is first heard?...

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...
