Aplanet has a mass of about 6.4 x 1023 kg, and its moon has a mass of about 9.6 x 1015 kg. if the magnitude of the gravitational force between the two bodies is 4.6 x 1015 n, how far apart are the planet and its moon?

The gravitation formula of Newton isF=Gm1m2r2F = the force between two bodies. G = gravitational constant. = about 6.67 *10^(-11) m1 and m2 = are the masses of the bodies interacting. r = distance between two bodies. u can read full description here https://en.wikipedia.org/wiki/Gravity Now I will seek the distancer=Gm1m2F−−−−−−−√=6.67∗10−11∗6.4∗1023∗9.6∗10154.6∗1015−−−−−−−−−−−−−−−−−−−−−−−−−−−−√= ABOUT 9.4*106 meter

The answer is 9.4x10 to the 6th power

           I hope this helped

Carbon-14 has a half-life of 5,730 years and most igneous rock is older than that.
