Scientists discover two planets orbiting a distant star. the average distance from the star to planet a is 8 au, and it takes 710 earth days for planet a to orbit the star. if it takes 1170 earth days for planet b to complete an orbit, what is the average distance from planet b to the star? au

11.2 AU

Explanation:

Applying Kepler's 3rd law, we can find out the average distance of planet B to the star.

This Law states that for planets orbiting a same star, there exists a fixed relationship between the average distance to  the star, and the period of his orbit  around it, as follows:

K = T² / d³

So , in this case, we can write:

(da)³ / Ta² = (db)³ / (Tb)²

Solving for db:

db = ∛8³.(1170)² / 710² = ∛1390.4 = 11.2 AU

c) up

hope this

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
