Correct answer:- (b) the natural result of gravity pulling everything toward a center.
Aristotle said that the spherical shape of the earth was the natural result of gravity pulling everything toward a center.
One of the first to realize that our globe is a sphere was Aristotle. He observed lunar eclipses and realized that the only object that could suggest a circular shadow was a sphere. General observations obtained at sea supported this astronomical finding.
Gravity.
All objects in the universe are drawn toward one another by the force known as gravity. All items on Earth are drawn "downward" by gravity toward the planet's core.
In physics, tension is defined as the pulling force that is transmitted axially through the use of a string, rope, chain, or similar object, or by the ends of a rod, truss member, or another similar three-dimensional object similar three-dimensional object. Tension can also be defined as the action-reaction pair of forces acting at the ends of the aforementioned elements.
