4. The solar wind consists of protons from the Sun moving toward Earth (the wind actu- ally consists of about 95% protons). The number density of protons at a distance from the Sun equal to the orbital radius of Earth is about 7 protons per cubic centimeter. Your rescarch team monitors a satellite that is in orbit around the Sun at a distance from the Sun equal to Earth's orbital radius. You are in charge of the satellite's mass spectrometer, and instrument used to measure the composition and intensity of the solar wind. The aperture of your spectrometer is a circle of radius 25 cm. The rate of collection of protons by the spectrometer is such that they constitute a mcasured current of 85 nA. What is the speed of the protons in the solar wind? (Assume the protons enter the aperture at normal incidence.)
