question doesn't say, id guessing it means the average position of an electron so maybe take 2p_x and find <x>

Homework Statement Where would the expectation value on a 2p orbital lie? and where would you likely find the electron relative to the maximum? Homework Equations found on a forum that the expectation value is n^2 a_0 but id like a more reliable source The Attempt at a Solution...

I figured it out...Moderator can close thread

Homework Statement A comet from the Oort cloud, with perihelion 6AU, is perturbed by Saturn into an orbit with perihelion 4AU. What is the semi-major axis and eccentricity of the new orbit? Homework Equations Perihelion = a(1-e) The Attempt at a Solution hey i could really...

cheers guys, sorted

heres the two vectors btw, not that its really important since the general rules for finding the cross product should be the same for all vectors Two vectors are given by a= 3.0 iˆ + 5.0 ˆj and b = 2.0 iˆ + 4.0 ˆj

How do you find the cross product when you are given two vectors in R2? i know how to do it for R3
