a) Which of the following is NOT a reason that Copernicus rejected the Ptolemaic model?
1. He rejected epicycles and deferents.
2. The different treatment needed for the inferior and superior planets seemed contrived.
3. Equants violated the physics of Aristotle.
b) Which one of the assumptions or statements below is part of BOTH the geocentric model of Ptolomy and the heliocentric model of Copernicus?
1. The sidereal periods of the planets increase outwards from the Sun.
2. The Moon circles the Earth in a month.
3. The Earth is at the center of the cosmos.
c) In the Copernican model, the diurnal motion of the celestial sphere is due to the
1. rotation of all of the celestial spheres around the Earth.
2. motion of the planets around the Sun.
3. rotation of the Earth on its axis.
d) Copernicus was the FIRST to show that
1. planets orbiting the Sun could produce retrograde motion.
2. the sidereal periods of planets increase with increasing distance from the Sun.
3.planets travel on elliptical orbits.
