Rosalinda wants to calculate the mass of Earth using Kepler’s laws or Newton’s universal law of gravitation.Which data would allow her to find the mass of Earth?

The Moon’s orbit around Earth can be used to determine Earth’s mass. For a nearly circular orbit, the relationship is M = 4π²r³/(GT²), where r is the Moon’s distance from Earth and T is its orbital period. Choice B provides both values; the Sun’s mass or Earth’s orbit around the Sun is not needed.
