1. If you took a gravimeter 100 m down a mineshaft and the gravity increased by 11.6 mg, what is the density of the overburden?
Homework Answers
There is no effect on mass of an object due to increase of weight, weight of an object having fixed mass depends on
acceleration due to gravity, weight is measure of force of gravity, density= mass/ volume
Since mass and volume is fixed so there is no change in
Density.

If a body of mass m falling from rest under the action of gravity encounters an air resistance proportional to the square of the velocity, then the body's velocity t sec into dv the fall satisfies the differential equation m- mg-kv, where k is a constant that depends on the body's aerodynamic properties and the density of the air. (Assume dt that the fall is short enough so that the variation in the air's density will not affect the outcome...
