1. Many people know that the weight of an object varies on different planets, but did you know that the weight of an object on Earth also varies according to the elevation of the object? In particular, the weight of an object follows this equation: , where C is a constant, and r is the distance that the object is from the center of Earth.

algebra 
drwls,
Your equation is inpt shown.
It should be something like:
W = C M/r^2
where r ais the distance mentioned, M is the mass of the object (which does not depend upon gravity) and C is a constant.
You have not asked a question, either.
