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?

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.

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.

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).
