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.

If a 1.00-kHz sound source moves at a speed of 53.0 m/s toward a listener who moves at a speed of 28.0 m/s in a direction away from the source, what is the apparent frequency heard by the listener? (Use 343 m/s as the speed of sound in air.) A) 795 Hz B) 937 Hz C) 1000 Hz D) 1086 Hz E) 1279 Hz
A. A sound source producing 2.90 kHz waves moves toward a stationary listener at one-half the speed of sound. What frequency will the listener hear? Express your answer in hertz. B. Suppose instead that the source is stationary and the listener moves toward the source at one-half the speed of sound. What frequency does the listener hear? Express your answer in hertz.
A sound source producing 1.00-{rm kHz} waves moves toward a stationary listener atone-half the speed of sound.The frequency that the listener will hear is2000 Hz.when the source is stationary and the listener moves towardthe source at one-half the speed of sound, the frequency that thelistener hear became 1500 Hz.Explain on physical grounds why thetwo frequencies differ.
The sound wave source moves away from a stationary listener at 80 m/s. The speed of sound is 340 m/s and the frequency of sound is 200 Hz. a) Find the wavelength of sound waves between the source and the listener. b) Find the frequency heard by the listener.
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...
Derive the Doppler effect equations of a moving source and a stationary listener for the following two scenarios: Source moving away from the listener and Source moving towards the listener. Thereafter, use your derived result to calculate the Frequency that would enter the listener's ear for the combined scenarios, if the speed of sound is 321m/s, the speed of source is 46.8 m/s and the source frequency of 188 Hz. Answer:
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.)
Homework 7.2 The sound frequency a listener hear will be shifted to a higher value if the listener is moving towards a stationary source or the sound source is moving towards the stationary listener. However, the shifts are not the same for the same speeds in these two cases. Derive the relationship of the two speeds (speed of the listener and the speed of the sound) for the same frequency shift assuming the sound speed relative to the medium is...
7. You are standing still on a day when there is no wind. Four different sources of sound are moving relative to you (either directly toward you or directly away from you). State whether each source is moving toward you or away from you and state how rapidly (in m/s) it is moving relative to you. The speed of sound in air is 343 m/s. Explain your answers. (a) Source 1 emits sound of frequency 125 Hz, but the sound...
ying a sound 3) If you are moving at a speed of 60 m/s toward a stationary sound source that is pla with a frequency of 900 Hz, what frequency do you observe
