alleryStretching your arms while spinning slows you because it increases your:
AAngular momentum
BTotal body mass
CExternal torque
DMoment of inertia

Correct answer: D. Moment of inertia
1. Mass moves farther from the axis.
2. That raises the moment of inertia.
3. With fixed angular momentum the speed drops.
