    Dirac Delta function and Divergence

    Homework Statement The Potential V(r) is given: A*e^(-lambda*r)/r, A and lambda are constants From this potential, I have to calculate: E(r), Rho(r) -- charge density, and Q -- total charge. Homework Equations The Attempt at a Solution I know that E(r) is simply minus...

    Undergrad Can You Determine an Epicenter in a Classroom Seismic Activity Simulation?

    Thanks for your reply. I really appreciate it. I'm going to talk to my teacher about the p-s wave issue today. So let's assume I know how to measure the distance for each three sensor. But do you still see this project impossible to conduct? Based on your observation, #5, it seems like, in...
