1. The mass of the Sun is about 2x10³0 kg. The Sun was about 72% hydrogen when it first formed.About 11% of the total amount of the Sun's hydrogen is available for fusion within the Sun's core.[3 points](a) What is the total mass of hydrogen available for fusion, in kg?(b) The Sun fuses about 600 billion kg of hydrogen each second. Calculate how long the Sun'sinitial supply of hydrogen can last. Give your answer in both seconds and years. Hint: use theresult you calculated in part (a).(c) We know that our Solar System is about 4.5 billion years old. Using your calculation above,how much longer do we have until the Sun runs out of hydrogen?

For 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?

(Astronomy) Light thermally emitted from the surface of a typical neutron star indicates that it has a temperature of 1,800,000 K. This temperature is about 300 times the temperature of the photosphere of the sun. This means that each square meter of the surface emits _______ more energy per second in thermal radiation than the photosphere of the sun.
