Hi! I have a question related to boundary condition in a one dimensional beam subject to compression and traction efforts.
In my class notes I have the following: If we consider a 1D beam of length L which is fixed at x=0 and subject to an effort F at x=0 we have the following boundary...
Hi! I am asked to calculete the portion of antimatter present in protons. I am sayed that this portion is given by:
r=(3R-1)/(3-R), where R is R=σ(antineutrino)/σ(neutrino). Another definition of r is r=∫x*Q'(x)dx/∫x*Q(x)dx, where Q(x) are partonic densities Q(x)=d(x)+u(x) (d is down quark and...
Hi, I am a physics student and i was asked to answer some questions about Hydrogen atom wavefunctions. I hope you can help me (sorry for my english, is not my motherlanguage, i will try to explain myself properly)
1. In order to find hamiltonian eigenfunctions of Hydrogen atom, we make then be...
