Consider an object with weight on the earth w_earth. the gravity of the earth is g. if it is moved to another planet with gravity a, how much will be its weight? note: you don't need to put a number for variables, m, w, a, g

Explanation:

We know that weight of an object on Earth is,

Thus,

where,

m = mass of an object, which is constant and is independent of gravity

g = acceleration due to gravity on Earth

On the new planet, gravity = a

Thus the weight of the object on the new planet will be

d) physical means can be used to separate the components of air.
