Question

Correct and rewrite Kepler’s third law.
“The period of revolution of a planet around the sun is directly
proportional to the cube of the distance of the planet from the
sun.

Answer 1

Answer:

Kepler's third law - sometimes referred to as the law of harmonies - compares the orbital period and radius of orbit of a planet to those of other planets. Unlike Kepler's first and second laws that describe the motion characteristics of a single planet, the third law makes a comparison between the motion characteristics of different planets. The comparison being made is that the ratio of the squares of the periods to the cubes of their average distances from the sun is the same for every one of the planets. As an illustration, consider the orbital period and average distance from sun (orbital radius) for Earth and mars.

Answer 2

Answer:

The square of period of revolution (T) of a planet around the sun is directly proportional to cube of average distance between planet and the sun.

The square of period of revolution (T) of a planet around the sun is directly proportional to cube of average distance between planet and the sun.{T}^{2} = K {r}^{3}T2=Kr3
