The orbital period of the Sun and the distance of the Sun from the center of the galaxy can be used to calculate which of the following?

Question

Quizplus · Accepted Answer

The orbital period of the Sun and its distance from the center of the galaxy are both factors that can be used to calculate the mass inside the Sun's orbit using Kepler's laws of motion and Newton's law of gravitation. Therefore, only choice A is relevant in this context. The age of the galaxy and the distance to the Andromeda galaxy are not related to these parameters. Similarly, the age of the Sun cannot be calculated from these parameters alone.
