Consider two clouds in the interstellar medium. A molecular (H2) cloud has T = 10 K and n = 1012 m-3; a neutral atomic (H) cloud has T = 120 K and n = 107 m-3.

(a) What is the Jeans mass for each of the two clouds?

(b) What is the minimum radius each cloud must have to collapse?

(c) What is the timescale for the gravitational collapse of each cloud?
