Homework Help: Thermal Physics - Energy Exchange

  1. Apr 9, 2010 #1
    1. The problem statement, all variables and given/known data
    Consider a collection of 100 oscillators, each with an average of 10 quanta.
    a) By what factor would [tex]\Omega[/tex](microstate) change if the total energy were increased by a factor of 2?
    b) By what factor would [tex]\Omega[/tex] change if one more oscillator were added to the original system without changing the total energy?

    2. Relevant equations

    3. The attempt at a solution
    I tried to use (q+N-1)!/(N-1)!q! but it doesn't work...

    The answer for a) is '2^99' and for b is 'a factor of 11'

    Could someone help me out here?

    Thanks a lot !

    I have just tried to substituted the value into the equation and it seems the answer is approximately correct a) 2^96.6 b) 10.9 (with N=100, q=1000).
    Maybe I misinterpret the question.
