Which of the following was not a major advantage of Copernicus's Sun-centered model over the Ptolemaic model? It made significan
tly better predictions of planetary positions in our sky. It offered a more natural explanation for the apparent retrograde motion of planets in our sky. It allowed calculation of the orbital periods and distances of the planets.
It made significantly better predictions of planetary positions in our sky
Explanation:
Of the following statements the one which was not a major advantage of Copernicus's Sun-centered model over the Ptolemaic model is that it made significantly better predictions of planetary positions in our sky. Both the model made similar predictions of planetary position in our sky. In fact the Ptolemaic model was even better than the Copernicus's heliocentric model when it came to positioning of planets.
B, the potential energy is transformed into kinetic. It is not A, because energy can neither be destroyed or created. And I remember the difference between the energy types as the meaning of potential (not in use; not yet at full) and saying that it is not moving.
