The total luminosity of the Sun is 4e26 Watts.a) What is the mass (in kg) that the Sun loses each second due to the conversion of nuclearbinding energy into radiation?b) The Sun has a total mass of 2e30kg and will live for 1e10 years. What fraction of theSun’s mass will be consumed in its lifetime due to nuclear fusion? Don’t forget that Wattsare measured in seconds.c) One of the interactions that takes place in the Sun’s core is the production of Deuterium.Two protons come together and one converts into a neutron. The mass of each proton is938.27209 MeV/c2. The mass of the deuteron is 1875.61294 MeV. How much energy isreleased during this process?d) During this process, the new nucleus releases two other particles. The initial particles,two protons, each have a quantum spin of +1/2 and an electric charge of +1. Now you havea proton, a neutron, a particle X, and particle Y. If the particle X has no electric charge,what is the electric charge of particle Y? If particle Y has a spin of…

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?
In class we found an expression for the 'garden hose angle', ψ, and showed it had a typical value close to 45° (or 225°) near 1 AU. How would we expect this angle to change for very slow solar wind speeds? Choose the best answer below: A. ψ → 0° B. ψ → 90° C. ψ → 180° D. Not enough information provided
