Question

what did isaac newtons investigations of gravity explain?
gravity acts on all objects in the universe.
jupiter has more moons than earth.
earth is not the center of the universe.
the sun is more massive than earth.

Explanation:

Isaac Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This means gravity acts on all objects in the universe. The other options (Jupiter having more moons than Earth, Earth not being the center of the universe, the sun being more massive than Earth) are not explained by Newton's investigations of gravity. The number of moons a planet has is related to its formation and capture processes, Earth not being the center of the universe was a concept from earlier astronomical models (like Copernican heliocentrism), and the mass comparison between the sun and Earth is a matter of their individual compositions and formation, not directly explained by Newton's gravity law in the context of what the law itself fundamentally describes about gravity's reach.

Answer:

Gravity acts on all objects in the universe.
