Question

some objects in space are created from clouds of gas and dust. what will happen if the cloud does not have enough mass? a core will form. a star will not form. a protostar will form. a nebula will not form.

Explanation:

For a star to form from a cloud of gas and dust (nebula), sufficient mass is required for gravitational collapse to create high - enough temperatures and pressures at the core for nuclear fusion to occur. Without enough mass, this process won't happen and a star won't form.

Answer:

B. A star will not form.
