Two identical planets, each with a mass of 1024 kg, orbit around the midpoint between the two planets. If the distance between the two planets is 2 x 108 m (as measured from their centers), how fast is each of the planets moving in their orbit?

each of the planets moving  = 408.35 m/s

Explanation:

given data

mass =   kg

distance between two planets = 2 × m

solution

if distance between two planet is 2 × m it mean it's diameter so

that radius will be 1 × m

and

F =    ................1

and

F =   ..............2

so from equation 1 and 2 will be

=    

v =     ............2

put here value

v =    

v = 408.35 m/s

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.
