[Spring2019] last question for tonight

Another one from Beth:

> m^2*kg*s^-2 I have to divide R by 100,000. Am I over complicating this?


everything should come out right if you consistently stick to cgs units,
i.e., if you were to calculate the frictional coefficient for BSA at 20C, 
you would do something like this:

        R          T         N           D           f
f = (8.314e+07 * 293.15)/(6.022e+23 * 6.03e-07) = 6.712e-08
