Why did Copernicus have to keep small epicycles in his models?
1 Actually, Copernicus did not use epicycles.
2 His model did not predict planetary positions as well as the Ptolemaic system.
3 It was the only way to explain retrograde motion.
4 Unlike the Ptolemaic system, all the planets were treated the same.

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
