When the figure skater squatted down during her spin, she didn’t speed up or slow down. Why did changing her shape in this manner not affect her spin?

for her angular velocity to increase, her moment of inertia must increase. You are correct, d is the answer. If you go to the website below, you can watch a video of an ice skater. To decrease her moment of inertia, she brings her arms and one leg closer to her body. The force that she exerts as she does this is producing a torque.

c-reactive protein (crp) is an acute phase protein belonging to pentraxin family of proteins, whose levels increases 1000-fold or more in concentration in blood during the occurrence of an injury, inflammation or tissue death.
