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 _________.
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.
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.

energy or thermal energy is transferred from the burning of wood to the
sausages for it to be cooked. The sausage is being heated by the fire and is
absorbing the heat or thermal energy.</span>
You could be lying completley still on your bed, and all though it seems you are at rest, you are moving along with the earth around the sun and hence are motion. This is why 'being at rest' is more of a relative term. Hope this helps!
