I am trying to calculate what the heat change from room temperature is in a wire loop is. I have the power P, the thermal conductivity K , the radius of the wire "a" and the radius of the loop "r". Using Fourier's Law:
P = -KA \frac{\Delta T}{\Delta x}
I am unsure what to use as A and...
From what I can tell the lower the energy the better the survival probability i.e. pp neutrinos have a better survival probability than 8B neutrinos. I'm not sure how this relates to the MSW effect. I am looking at this purely qualitatively.
My understanding of solar neutrino physics is pretty basic as I'm currently trying to get to grips with this field. I have a reasonable understanding of particle physics in general.
I am trying to explain why why the survival probability for solar neutrinos is different for different neutrino solar lines, and what causes this difference.

In the lectures, we considered a dipole, made of two charges ±q at a separation d. Using
Dirac's δ function, write the charge density for this dipole.
Evaluate the charge (monopole moment), dipole moment, and quadrupole moments Q, p,
and Qij in the multipole expansion...
I am currently doing a past paper question for my electromagnetism exam and I can't seem to figure out this problem, it is probably quite simple but I can't see a solutionHomework Statement
Consider a spherically symmetric charge distribution:
ρ(r) = ρ0(r/r0)-n for r>r0
ρ(r) = ρ0 for r≤r0...
Thank you. The problem was that I was assuming the current to be the same throughout the whole of the loops which was giving me some weird answers. Completely forgot about the junction rule.
Thank you very much for your help
