Sir isaac newton has discovered many laws, besides the laws of motion. (a) what law of nature did newton discover? (b) how did he relate his discovery to the relationship between the earth and the moon?

a.  Besides his work on universal gravitation (gravity),Newton developed the three laws of motion which form the basic principles of modern physics. His discovery of calculus led the way to more powerful methods of solving mathematical problems.

b.If it was the same force, then a connection would exist between the way objects fell and the motion of the Moon around Earth, that is, its distance and orbital period. ... Newton went further and proposed that gravity was a "universal" force, and that the Sun's gravity was what held planets in their orbits

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.

your answer should be c) enjoy!
