Graduate Finding Charge Conjugation Eigenvalues
Ah I see, that makes sense. So charge conjugation in fermions is similar to parity then (when you say you need to exchange angular momentum/spin to return to the original state), or is this not a good way to think about it?- v0id19

Graduate Finding Charge Conjugation Eigenvalues
I've just recently been introduced to charge conjugation while reading the introductory particle physics texts by Griffiths and Perkins, and neither one really seem to explain how you go about finding the values for C. For example, if I wanted to find the value for the \rho^0 meson (which I...- v0id19

How can I normalize a plot by the cross-section in particle physics?
Just a quick question--long story short, I need to normalise a plot by the cross-section, but I'm not sure how to do that and the Google hasn't been too helpful. I was thinking about scaling it by the cross-section times the luminosity--does this sound reasonable?- v0id19

Sliding bar constraint equations
Thanks, this is what I wanted to do, but the fact that the question specifies cartesian coordinates is what's confusing me. I agree that it makes much more sense to do it this way. I'll check the other thread and see if it helps.- v0id19

Sliding bar constraint equations
Homework Statement A uniform rod of length l rests on a horizontal floor and leans against a vertical wall, making an angle \theta with the floor. It is initially held at rest. At t = 0, the rod is released and falls, sliding on the floor and the wall with no friction. The only forces acting on...- v0id19

How Does Transcranial Magnetic Stimulation Induce EMF in Brain Tissue?
hmm apparently my hint wasn't help... Faraday's law: E \cdot dl = -\frac{d\Phi}{dt} You know dl, and can calculate the change in flux, so you can solve for E...- v0id19

How Does Transcranial Magnetic Stimulation Induce EMF in Brain Tissue?
Well what have you tried so far to solve these? Remember Maxwell's equations; they are the tools you'll need to solve most E&M problems at this level. Specifically, Faraday's Law will help with part (a).- v0id19

Projectile Motion - formula derivation
You have said that the clue is that the formula is derived from I assume this means v^2 \cdot \frac{sin(2\theta)}{g}? Also, a statement of the actual question would be very helpful.- v0id19

How Do You Calculate Invariant Mass in Particle Physics?
Homework Statement so I'm doing some proof-of-concept data analysis this summer and I've never taken a relativistic mechanics class and I'm a bit stuck. i need to figure out if there was a rho0 decay to pi+/pi- in some hypothetical 900GeV collision data. If there is, there should be a spike...- v0id19

Work by an ideal gas, thermodynamics
yes, but I don't have any of the equations for the lines on the graph. using the energy equation (E=Qin+W). for an isothermal process E=0, so Qin=-W, and W=PdV=∫(nRT)/V*dV=nRT*ln(V2/V1)- v0id19
