Question

Imagine that a star-forming cloud collapses but retains all of its mass in a single blob. In order to conserve angular momentum, the cloud must Imagine that a star-forming cloud collapses but retains all of its mass in a single blob. In order to conserve angular momentum, the cloud must _________.

Answer 1

Answer: In order to conserve angular momentum, the cloud must spin faster

Explanation: Angular momentum is a vector quantity that is used to describe the property of a rotating object. It can be derived by the multiplication of the moment of inertia and the angular velocity of the object. Angular momentum depends on:

-the mass of the object,

-how far it is spinning,

-whether the mass is close to or far from the center of the mass and spin.

if the distance of the mass from the center of the cloud decreases, the rate of spin must increase to compensate.

Answer 2

The correct answer is spin faster.

Step-by-step explanation:

The angular momentum or kinetic moment is a physical magnitude, rotational equivalent of the linear momentum and represents the amount of rotational movement of an object. It is a vector quantity that characterizes the inertia properties of a body, which rotates in relation to a certain point. It is found in the three mechanics (classical, quantum and relativistic mechanics). In the International System of Units the angular momentum is measured in kg · m² / s. This magnitude plays a role similar to the linear moment in the translations with respect to the rotations.
