- Differentiate betwen geostationary and polar satelites.Why does nuclear fusion in the sun occur only near the center?If the color of the sun's photosphere's maximum intensity light is green, is this the color we normally observe for the photosphere? Why or why not? (I would assume it is not, but I do not know why...)
- If you were located 100 km from a 1 GW nuclear power plant,what would the neutrino flux be at your location? Assume that a1 GW nuclear power plant releases 1021 neutrinos per second andyou present a 1 m2 surface to the neutrino flux.Why does nuclear fusion only take place in the Sun’s core?Why are emission nebulae red ?
