Physics

Assuming a composition entirely of atomic hydrogen, and adensity of
1.67x10-19 kg/m3, use the formulae for JeansMass and Radius (where
appropriate), to determine which of the following gas clouds willcollapse:
Cloud A: Mass = 10,000 Msun, T = 120K
Cloud B: Mass = 7,000 Msun, T = 80K
Cloud C: Radius = 8 pc T = 60K
