The Question Consider two energy states, E2 = 2.0 eV and E1 = 1.0 eV. Assume that there are 1.0 x 10^16 electrons/cm^3 in E2 and 1.0 x 10^15 electrons/cm^3 in E1. What temperature is required to create this population distribution in thermal equilibrium? How do you define the...

Please HELP! Differential Equations I can't for the life of me figure out how to do this. I've heard its pretty straightforward given the code on the webpage. (All is needed is that you modify the code) This is the assignment: http://www.math.mcmaster.ca/~bprotas/MATH4Q03a/hw5.pdf...

Hello, I have a question concerning the angle of deviation of the rays that exit out of the wollaston prism. (A wollaston prism is basically composed of two different crystal orientated blocks cemented together, each having a different index of refraction depending on the optical axis) My...

How would i start to derive the magnetic field intensity and initial velocity for a free electron to circle around a radius of 100 nm?

I'm currently taking a class on engineering communications. Don't worry this isn't asking for numerical homework help but rather to brainstorm physics topics that can be demonstrated and presented in a 15 minute interval. Past projects extended by electrogravity, where they put a lot of...

I've tried question #1 on here: http://www.pa.uky.edu/~cvj/PHY404G/phy404g98_test1/phy404g98_test1.html for the past 10 hours, i have achieved getting something relatively close, but i cannot do the algebra to prove t=cosh^(-1) etc etc... has anyone done this problem in the past, i know...
