Answer:

The answer is: Greater than.

Explanation:

It is well known that a gas cloud is very vast in relation to the diameter of the star, and that is why the angular momentum is maintained, the angular velocity must increase as size decreases. This is why the star will rotate much faster than the angular velocity of the gas cloud.

Answer:

Greater than

Explanation:

Here, angular momentum is conserved.

l_1\omega_1 =l_2\omega_2

When the cloud shrinks under the right conditions, a star may be formed.

Thus, Diameter of clouds are much higher than a star.

Moment of inertia of cloud is greater than the star's inertial.

so, angular velocity of the star would be greater than angular velocity of the rotating gas.
