24. Which of the following was not a major advantage of Copernicus’s Sun-centered model over the Ptolemaic model? (a) It made significantly better predictions of planetary positions in our sky. (b) It offered a more natural explanation for the apparent retrograde motion of planets in our sky. (c) It allowed calculation of the orbital periods and distances of the planets.

(a) It made significantly better predictions of planetary positions in our sky.

Explanation:

Which of the following was not a major advantage of Copernicus’s Sun-centered model over the Ptolemaic model:It made significantly better predictions of planetary positions in our sky.

Copernicus’s Sun-centered model  was created by Nicolaus Copernicushins where his model positioned the sun near the center of the universe, motionless with Earth and the other planets orbiting around it in circular paths, modified by epicyles and at uniform speeds. Copernicus model says that the sun is at rest near the center of the Universe and that the earth spinning on it axis once daily, revolves annually around the sun. this theory correctly assumed the position of the sun and the moon is orbiting around us, it made better predictions of the planetary position in our sky

The advantage of this model is that it explain few unrelated coincidences that exited in the Ptolemaic system
