The Formula for the Jeans Length Is , Where

Multiple Choice

The formula for the Jeans length is , where m is the single particle mass and ρ_m is the density. Population III stars formed in the early universe where the material consisted almost entirely of hydrogen and helium rather than material enriched by heavy elements. Thus, for the formation of Population III stars, L_J was:

A) small because ρ_m was large.
B) small because m was large.
C) large because m was small.
D) unaffected by the composition of the material.
