If a chicken has a weight of 300N on Earth, what would be its weight on Mercury if the gravity is 0.38.​

it would be 25.44 lbs

Explanation:

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
