This is an example of conservation of angular momentum.
The ice skater will rotate more slowly because her arms would be considered the outside torque that is impacting her constant angular momentum.
So, an ice-skater who throws her arms out will rotate more slowly.
I think its true. hope this helps.
I would expect it to be slightly basic.
<em>A statement that is true for ALL of the examples of electromagnetic waves is that;</em>
A) They all move at the same speed in a vacuum
<u>The reason for qualifying 'in vacuum' is because EM waves of different frequencies often propagate at different speeds through material. Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum.</u>
