SHM question

  1. Jan 21, 2010 #1
    A tuning fork oscillates with simple harmonic motion described the equation:

    x = 0.00150cos(2770t) (where t is seconds)

    a) calculate the frequency in Hz of the tuning fork

    b) Suggest why only this tuning fork (taken from a set of 10 forks) gets louder when held above a glass bottle full of milk.

    I dont know how to go about this question. Any help greatly appreciated.

    A look at http://en.wikipedia.org/wiki/Simple_harmonic_motion, especially at the first formula encountered, will give you the straightforward answer.
