Homework Help: Amplitude and inter atomic separation

  1. Dec 23, 2011 #1
    1. The problem statement, all variables and given/known data
    The question goes something like this:
    What % of inter atomic separation is the root mean amplitude.
    The data given is:
    Inter atomic separation : 0.29nm , T =300k , D = 20 N/m , Aluminium atomic weight 27 g/mole.
    How do I proceed I have no idea on how to relate mean inter atomic separation and rms of the amplitude.

    2. Relevant equations

    Formula to calculate Root mean amplitude is : √KbT/D

    3. The attempt at a solution

    As above.
