Question

The Earth revolves around the sun every 365.25 days."" This is the example of which:

a) Law of Gravitation
b) Kepler's Third Law
c) Newton's First Law
d) Heliocentric Theory

Answer 1

The Earth's revolution around the Sun in 365.25 days is an example of Kepler's Third Law, which relates the orbital periods of planets to their distances from the Sun.

Step-by-step explanation:

The statement "The Earth revolves around the sun every 365.25 days." is an example of Kepler's Third Law of planetary motion. Kepler's Third Law, also known as the Law of Harmonies, describes the relationship between the time it takes for a planet to orbit the Sun (its period) and its average distance from the sun. Specifically, it states that the ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their semi-major axes (average distances from the Sun).

This means that the farther a planet is from the sun, the longer it will take to complete one orbit. The Earth's orbit around the Sun takes approximately 365.25 days, which is why we have a leap year every four years to account for the extra quarter-day.
