1. ### What can be said of the frequency of the note the trombone is playing?

the frequency is greater than 250 Hz the beats at 250 means you are close, and if the beats increase as you lower the frequency, that means you are going in the wrong direction.

2. ### Note : The symbol for an Atomic Mass Unit is “u”. A proton of mass 1 u undergoes a headon elastic collision with a stationary atomic?

CoM of system has velocity Vcm = 1u*472m/s / 15u = 31.5 m/s For an elastic, head-on collision, we know (from conservation of energy), that the relative velocity of approach = relative velocity of separation, or 472 m/s = V - U where V is the post-collision velocity of the nucleus and...

5. ### a guitar string transmits waves at 509 m/s. to create a 491 Hz note , to what length should the guitar player shorten the string?

length λ = V/f = 509 m/sec / 491 sec^-1 ≅ 1.0 m (on a guitar???)

6. ### True or False: The note C on a flute and the note C on a clarinet of the same frequency would be indistinguishable if drawn as a wave.?

Depends on what you mean by "if drawn as a wave." If the two instruments are playing the same C (that is, they are in the same octave), and the wave represents only the primary wavelength associated with that frequency, then...

7. ### Describe what you hear when a musical note at 294 Hz is played at the same time as another note at 299 Hz.?

Well, you definitely hear beats with a frequency of 5 per second (e). You would probably also claim to hear dissonance (a).
