Conceptual Example 14 provides background for this question. A cloud of interstellar gas is rotating. Because the gravitational force pulls the gas particles together, the cloud shrinks, and, under the right conditions, a star may ultimately be formed. Would the angular velocity of the star be less than, equal to, or greater than the angular velocity of the rotating gas

Answer:

Greater than

Explanation:

In the given case we apply the law  of conservation  of angular momentum which is

[tex]l_1\omega_1 =l_2\omega_2[/tex]

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.

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