On the planet Arrakis, a male ornithoid is flying toward his stationary mate at 25. 0 m/s while singing at a frequency of 1200 Hz. If the female hears a tone of 1240 Hz, what is the speed of sound in the atmosphere of Arrakis? Rank 1 2 3 4 5 6 Responses
While sitting in your vehicle out in the boonies, you see your friend, who just so happens to have the exact same make/model of vehicle as you, driving your way. You blow your horn which has a frequency of 260 Hz. Your friend blows their horn in response. You hear a beat frequency of 6 Hz. How fast is your friend approaching you (in m/s)? You may assume v = 344 m/s. Rank 1 2 3 4 5 6 Responses
While sitting in your vehicle out in the boonies, you see your friend, who just so happens to have the exact same make/model of vehicle as you, driving your way at 7/8 m/s. You blow your horn which has a frequency of 260 Hz. What frequency does your friend hear your horn at? You may assume v = 344 m/s. Rank 1 2 3 4 5 6 Responses
Consider the two scenarios: (A) A stationary object produces a sound at a fixed frequency f. Another object moves toward the source with a fixed velocity v. (B) An object producing a sound of frequency f moves towards a stationary observer with a velocity v. The perceived frequency of sound is for scenarios (A) and (B) A. differ. B. are the same. C. not enough info.
A stationary source emits a constant sound of frequency of 1300 Hz. You travel towards the source at 25 m/s. At what frequency do you hear the sound? (Speed of air is 344 m/s). Rank 1 2 3 4 5 6 Responses
