what is used to measure the different speeds that different stars spin at?
actual motion
absolute magnitude
angular momentum
nuclear fusion

Explanation:

• Actual motion refers to the real - world movement of an object. For stars, their spin motion is a part of their actual motion.
• Absolute magnitude is a measure of the intrinsic brightness of a star.
• Angular momentum is a measure related to the rotational motion of an object (mass × velocity × radius), but it is not directly the measurement of the spin speed.
• Nuclear fusion is the process by which stars generate energy.

Answer:

actual motion
