The gravitational force of a star on an orbiting planet 1 is f1. planet 2, which is twice as massive as planet 1 and orbits at three times larger distance from the star, experiences gravitational force f2.
what is the ratio f2f1? you can ignore the gravitational force between the two planets.

ratio = 1 : 4.5

Explanation:

If m₁ is the mass of the star and m₂ the mass of the planet, the force of gravity F₁ for planet 1 is given by:

The force F₂:

The ratio:

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
