A whistle of frequency 556 Hz moves in a circle of radius 57.6 cm at an angular speed of 16.4 rad/s. What are (a) the lowest and (b) the highest frequencies heard by a listener a long distance away, at rest with respect to the center of the circle? (Take the speed of sound in air to be 343 m/s.)
phons 100 9 80 60 A 40 20 20 10k 1000 100 10 Frequency Hz) a) At approximately what frequency is the human ear most sensitive? How can you tell? b) If you heard a 300-Hz tone with a sound level of 60 dB, approximately how many phons would you perceive? toward you with a speed v, starting a distance of 1 km away att 0. If the train moves very slowly (that is, v is extremely small compared to...
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 bystander hears a siren vary in frequency from 562 Hz to 394 Hz as a fire truck approaches, passes by, and moves away on a straight street. What is the speed of the truck? (Take the speed of sound in air to be 343 m/s.)
6) The sound from the whistle of a truck moving at 17.0 m/s toward a cliff reflects from the cliff and is heard by the driver of the truck. When it is parked at the side of the road, the whistle from the truck produces sound of frequency 2.267 kHz. As observed by the driver of the truck, what is the change in frequency the sound from the whistle due to the reflection? The speed of sound is 343 m/s....
Sound Waves- In class Qui 1. What is the frequency heard by a person driving at 15 m's toward a blowing factory whistle C the speed of sound is 340.6 m/s? (800. Hz) if 2. F rom the previous problem, what frequency would he hear after passing the factory if he continues at the same speed? 3. Determine the speed of a wave that is travelling with a frequency of 400Hz and has a wavelength of 45m. 4. A cop...
The siren on an ambulance is emitting a sound whose frequency is 2850 Hz. The speed of sound is 343 m/s. (a) If the ambulance is stationary and you (the "observer") are sitting in a parked car, what are the wavelength and the frequency of the sound you hear? (b) Suppose that the ambulance is moving toward you at a speed of 26.6 m/s. Determine the wavelength and the frequency of the sound you hear. (c) If the ambulance is...
You buy a super cool dog whistle that emits sound at a frequency of 19 000 Hz. Unfortunately when you blow it you notice no response from your dog, so wonder if the whistle is broken. From experimenting during your sound wave lab you know that you can hear up to a frequency of 18 500 Hz. You give the whistle to a friend of yours and ask him to blow it while riding on a bike to see if...
