- 13 What is the solar wind? (A) The uppermost layer of the Sun, lying just above the corona B A stream of charged particles flowing outward from the surface of the Sun с D The wind that causes huge arcs of gas to rise above the Sun's surface The strong wind that blows sunspots around on the surface of the SunWhat is the ultraviolet catastrophe?Use Wien's Law to calculate the peak wavelength of light coming from the Sun. Assume T=5800 K for the surface temperature of the Sun. Wein's displacement law says that the blackbody temperature and peak wavelength multiplied together give a constant of 0.29 cm-K. (K is degrees Kelvin).
- What percentage of the energy we use comes from the sun? 25% 50% More than 90% Less than 10%What is the temperature of the Sun (google for the answer)? What is the re-entry temperature of the Space Shuttle (google for the answer)? Why don’t you burn up at the reentry temperature of 17318.5K for this Mach 20 flow? Why do you think that the body should actually re-enter the Earth's atmosphere in the opposite direction. (ie.. blunt/flat surface first.)Earth tugs the Sun around as it orbits, but it affects the radial velocity of the sun by only 0.09m/s. How large a shift in wavelength does this cause in the Sun's spectrum at 575 nm?
