Question:
Which situation describes the best example of rotational motion?
A. Craig sent the pool ball spinning toward the side pocket.
B. The skater repeated the figure eight on the ice.
C. Sara spun the dreidel on its pointed end.
D. The mouse ran in circles around the mousetrap.
Answer :
C
Explanation:
It's C, because it is spinning. It can't be D because it's going in a circle, not spinning. it can't be A because it doesn't really make sense. It can't be B because the Skater is repeating, not rotating. So the only logical answer is C.

The way scientists know that a hypothesis in astronomy is a reasonable description of nature is to do experiments and observations about the prediction of the hypothesis.
Given an incomplete sentence related to hypothesis and astronomy.
We are required to complete the sentence.
A hypothesis is basically a testable statement about the relationship between two or more variables or a proposed explanation for some observed phenomenon.
Astronomy is basically the study of everything in the universe beyond Earth's atmosphere.
The statement can be completed by "do experiments and observations about the prediction of the hypothesis".
Hence the way scientists know that a hypothesis in astronomy is a reasonable description of nature is to do experiments and observations about the prediction of the hypothesis.
