Perfect. Thank you very much!

[PLAIN]http://rpmedia.ask.com/ts?u=/wikipedia/commons/thumb/e/e8/Electron-scattering.png/220px-Electron-scattering.png This is how we would draw it. Thank you very much for your help! This is not asked for, but I'm curious. Is the interaction force the weak force? If so, which is the...

We have done only basic Feynman diagrams, we haven't been told about different types of diagrams. Again, since we haven't been told anything about different types of collision, I assume it is elastic. So "scattering from each other" means that in the intial state I just have two neutrinos? That...

Homework Statement I'm asked to draw a Feynman diagram for two neutrinos scattering from each other. Homework Equations None The Attempt at a Solution I don't really get the question so I don't know what I'm actually supposed to put in the diagram. Am I supposed to draw a diagram...

Thanks for the answer. I know what I have to do, but I don't know how to construct the expression for the kinetic energy. Any hints?

No, actually the liquid also has some acceleration, so I can't do that. I have to show that kinetic energy is a function of x^2.

Homework Statement Consider a column of liquid (density ρ) of length ℓ confined in a U-tube of uniform cross-sectional area A. Suppose that the water level on one side is pushed down a small amount and then released. 1) Construct expressions for the potential and kinetic energies of the...
