The complete question is
What modifications did kepler make to copernicus’s model? check all that apply. planetary orbits are elliptical. planets closer to the sun move faster. planets spin in an epicycle while orbiting earth. venus has phases due to its orbiting of the sun. earth’s rotation causes the rising and setting of the sun.
Answer:
Planetary orbits are elliptical.
Planets closer to the Sun move faster.
Step-by-step explanation:
The first option is based on the first law that states that the planets orbit the sun in ellipses, with the sun at one focus of the ellipse.
The second option is based on the third law that states that the square of the time of revolution about the sun is directly proportional to the cube of the mean radius of orbit of the planet.
