Explain.arrow_forwardFor several hundred years, astronomers have kept track of the number of solar flares, or sunspots which occur on the surface of the sun. The number of sunspots counted varies periodically from a minimum of about 10 per year to a maximum of about 110 per year. Between the maximum that occurred in the years 1750 and 1948, there were 18 completed cycles. A.) What is the period of the sunspot cycle? B.) Assume that the number of sunspots varies sinusoidally with the year. Sketch a graph of two sun spot cycles, starting in 1948. C.) Write an equation expressing the number of sunspots per year in terms of the year. D.) what is the first year after 2000 in which the number of sunspots will be about 35? A maximum?arrow_forward
- Based on what you learned about the source of stellar energy and how stars make energy, select all of the correct statements from the following list. 1. Many stars make energy with the proton-proton cycle. 2. The CNO cycle is more efficient than the proton-proton cycle. 3. The sun's energy comes from the CNO cycle.More massive stars make energy with the proton-proton cycle. 4. The leftover mass in both the proton-proton cycle and the CNO cycle is converted to energy. 5. A helium atom is more massive than four hydrogen atoms. 6. The CNO cycle requires a higher temperature than the proton-proton cycle.arrow_forward1) What is thermal equilibrium? Is the Sun in thermal equilibrium?
