I have to design an egg drop experiment for a teaching project. I'll describe the project and how everything works, then the students have about half an hour to create a container to shelter the egg so that it doesn't break from a fall of about 20 feet. The sticking point is the time limit. I...

Nevermind, I found it. Thank you. :)

I don't know if you're asking me if he gave any other equations (no, he didn't), or telling me I need those equations, haha.

Homework Statement Remembering that a bound state exists if the effective potential is negative, find an angular momentum quantum number l0 such taht for all l<l0 the states are bound. The given potential is V=(C/r3)-(D/r2), where C and D are positive numbers. Homework Equations...

Nevermind, I found it. :)

I figured it out, thanks for the help. :)

Homework Statement In this problem all vectors and operators are represented in a system whose basisvectors are the eigenvectors of the operator Lz (the third component of the angular momentum). a) Find the eigenvector |l=1,my=-1> of Ly in terms of the eigenvectors of Lz. b) Go from the...

Homework Statement Given is an infinite square well potential. V=infinity at x=a, x=-a. V=0 between -a and a. Take an even state u=Ccos(kx), and find <x>,<x^2>,<p_x>, and <(p_x)^2>. Your final answers should not contain k, which will be eliminated by the boundary conditions. Homework...

Nevermind, I got it. Thank you!

Ahhh, thank you! Am I on the right track to normalize the state initially?

That makes sense, but where am I supposed to get the hbar and -hbar from? Am I missing something really obvious?

Homework Statement A particle is in an angular momentum state Ψ(θ,φ) = |l=1,m=1> + 2|1,0> + 3|1,-1> Normalize this state and find the probabilities for finding the system with its third component Lz with values hbar, 0, -hbar. Homework Equations The Attempt at a Solution...
