Homework Statement
What is the Jean's length in parsecs for a typical neutral hydrogen cloud, which has a density of n(H I) ~10^8 atoms/(m^3) and a temperature of 100K?
Homework Equations
jean's length = sqrt[(15*K*T)/(4pi*G*u*p)]
where:
'K' is the Boltzmann constant
'T' is the temperature of the cloud
'G' is gravitational constant
'u' is Mu or the mass per particle
'p' is Rho or the density of the cloud
I'm assuming 'u' is the mass of a hydrogen atom in kilograms or 1.67*10^(-27)kg?
The Attempt at a Solution
jean's length = 12160m?
That seems far too small for any plausible answer in astronomy, these are usually measured in parsecs
