Oh wow, duh. It's been over a year since I've taken quantum and I assumed the distribution would be relevant somehow.

Homework Statement Show that for real valued E a particle at rest can not decay. Homework Equations Width of resonance. \Gamma=\hbar/\tau Relativistic Breit-Wigner distribution P_rel_=\Gamma/((E^2-M^2)^2+M^2\Gamma^2) Wave function of particle at rest. ψ(t)=ψ(0)e^(-iEt/\hbar) The...

Homework Statement I am given a distance at which a particular object is just discernible and am asked to find the opacity of the air.Homework Equations The Attempt at a SolutionI know that: I(x)=I0e-kρx but I don't know at what point you have total extinction. Obviously you would only have...

Well given that the two chambers are insulated I would say adiabatic. So the change in heat would be zero so: ΔU+W=0

Homework Statement A cylinder of cross-sectional area A is divided into two chambers 1 and 2, by means of a frictionless piston. The piston as well as the walls of the chambers are heat-insulating, and the chambers initially have equal length L. Both chambers are filled with 1 mol of helium...
