What do you mean by the end points. Is that the length of the wire?

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...

Can you have a left handed pion? i.e. it's spin is opposite to its direction of flight

Could there be some effect from neutrino-neutrino interactions in the sun's neutrinosphere?

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.

Sorry, I have corrected the question now. I need some help explaining it. I am referring to the solar neutrino energy spectrum

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.

Homework Statement 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...

F=qvxB F/q=vxB F/q=1600i x B F/q=-1600j + 1600k (2.1x10-16/1.6*10-19)/1600 = B Then used Pythagoras to calculate the magnitude of B

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

Thank you, I have now attached the picture

Homework Statement In the circuit shown in the link, the 6.0 \ohm resistor is consuming energy at a rate of 24.0 J/s when the current through it flows as shown. A) Find the current through the ammeter A. B) What is the polarity and emf of the battery \epsilon assuming it has negligible...

You should see us here at the university of sussex, there are no shy physicists!
