Laws of planetary motion include that each planet travels in an elliptical orbit around the sun, and that an imaginary line from the sun to any planet sweeps equal areas in equal time intervals. a. newton’s c. galileo’s b. kepler’s d. copernicus’

b. Kepler’s

Explanation:

Kepler’s law is related to areal velocity. It states that any planet which is revolving around the sun sweeps an equal area in equal intervals of time i.e. areal velocity of these planets is constant. He also stated that sun is the focus of all the planets revolving around it and they move in elliptical orbits around it.

This law does not consider gravitational interactions which exist among various planets which revolve around the sun.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.
