1. The problem statement, all variables and given/known data Hello Guys :) I have been studying neutrinos this term in physics and have been trying to calculate the neutrino flux on earth. I have found an equation but I am just unsure about what the variables in the equation stand for. 2. Relevant equations F = N/(A t) = E/(A t) × N/E 3. The attempt at a solution I know that F is the neutrino flux, but I am just unsure of what the other ones stand for. Is this the right formula or is there a formula that is better or easier to understand? Thank you!
