1. The problem statement, all variables and given/known data If, (average solar wind properties at Earth's orbit) Proton density = 7 cm^-3 flow speed=400km/s almost radial electron density=7.5 cm^-3, proton temp=2*10^5 Kelvin He^2+ density= .25 cm^-3 electron temp=1*10^5 Kelvin Magnetic field=7nT Find flux through sphere and flux densities of radius 1AU for: protons, thermal energy, magnetic energy, radial magnetic flux, kinetic energy, radial momentum, and mass 2. Relevant equations ?? 3. The attempt at a solution Attempted many times and not getting very far.. a start on the problem will be greatly appreciated -Thanks!
