if
the average solar wind density at 1 AU is 5 particles/cm traveling
at 400 km/s. (a) How many particles per second passes through each
squared meter at Earth's orbit? (b) Assuming a uniform solar wind
distribution, what is the total mumber of particles escaping from
the Sun? (e) What is the total mass, assuming a composit ion of 95%
H + 5% He? (d) What is the mumber density of the solar wind at
Saturn's (10 AU)? Assume that the solar wind velocity remains
constant at 400 km/s.
