Solar Neutrino Flux: Understanding Variables in Equation

AI Thread Summary
The discussion focuses on calculating the solar neutrino flux using the equation F = N/(A t) = E/(A t) × N/E. The variables in the equation are clarified, with F representing neutrino flux, N as the number of neutrinos produced, A as the area over which they are spread, and t as the time of production. The equation also incorporates energy, where E/t denotes the power of the Sun converted into neutrinos, and N/E represents the energy per neutrino. Participants confirm that this is a general formula for flux calculations. Understanding these variables is essential for accurate neutrino flux calculations.

Homework Statement



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.

Homework Equations



F = N/(A t) = E/(A t) × N/E

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!

Well, this is a general formula for any flux essentially. N is the number of of neutrinos produced, A is the area they are (evenly) spread over, and t is the time they were produced in. In the second step, the total energy R has been introduced. The first factor is then the energy flux, E/t is the power of the Sun into neutrinos and the second factor is the reciprocal of E/N, the energy per neutrino.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
