I understand this in theory, but I'm not sure if I am doing it correctly in practice. The first thing I did was look at a picture of a unit circle to help orient me. I figured this would be the best course of action because I will end up with a perfectly circular rotation of the Earth around...

Homework Statement This is for my computer simulations in physics class. The problem, as stated, is to numerically integrate a particular equation for a period of one year, given that the Earth starts at the point (1,0) with a velocity of (0,2pi). Then, I must plot the orbit. I am using Maple...

Homework Statement Suppose a wire has a radius R and a current density of J = I_0 \frac{x^2} {R^4}\hat{k}. Taking the wire to have cylindrical geometry, calculate the total current flowing down the wire, defined as I = \int J \cdot \vec{dA} . Homework Equations J = I_0 \frac{x^2}...
