Answer:
Density is equal to m/v where m is mass and v is volume. Even though the blocks have the same mass, they may have different volumes and therefore they will not have the same density.

Explanation:
Got it right on Acellus, you take the velocity and divide it by 4 times the length.
Answer:
An increase in angular speed due to conservation of energy priciple.
Explanation:
This leads to a decrease in your moment of inertia. This means that your angular velocity must increase as a result of conservation of energy principle and therefore you will spin faster.
It's also the same way this conservation of energy principle applies to ice skaters that makes them spin faster when they suddenly draw their arms inwards.
This is the answer just double it
