Here is another example of using your library of physics concepts.
Scientists have deduced that a distant galaxy is in rotational motion because they observed that two EM waves emitted from two different locations within the galaxy have different frequecies. Which law did they use to deduce?
A) Conservation of Angular momentum
B) Law of Gravitation
C) Hyguen's Principle
D) Doppler Effect
