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.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
