Explanation:
A scientific claim is defined as a statement which is a conclusion obtained from numerous experiments and observations.The scientific claim usually remains the same in the provided conditions. In the first statement, Copernicus's model stating that the planets revolve in the circular orbits around the sun was not accepted and thus, it is not a scientific claim. Similarly, Newton's laws of motion are uniform and work properly in the environment. Thus, it also does not form a scientific claim.
