Homework Help: Space Physics (sun and solar wind) problem

  1. May 9, 2012 #1
    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
