**Problem 1: Sun's Mass Loss Due to Nuclear Reactions and Solar Wind****a)** Calculate the rate at which the Sun's mass is decreasing due to nuclear reactions (\(\Delta m/\Delta t\)). Use the formula \(E=mc^2\) and the given solar luminosity (\(L_{\text{Sun}} = 3.839 \times 10^{26}\) W). Provide your answer in solar masses per year (\(M_{\text{sun}}/\text{year}\)).**b)** Determine the rate of mass loss due to solar wind. Use the given parameters: velocity \(v = 500\) km/s (as measured on Earth), particle density \(n = 7 \times 10^6\) particles/m\(^3\), and mean molecular weight \(\mu = 1\).**c)** Assuming that the rates from both processes remain constant throughout the Sun's main-sequence lifetime (approximately \(10^{10}\) years), evaluate whether either mass loss process would significantly affect the Sun's total mass.

The Sun is powered by releasing hydrogen to helium. Through either the proton-proton chain or the CNO cycle, the basic reaction is 4 1H morph into 1 4He, releasing nuclear binding energy (and losing mass) in the process. The mass of one proton 1H is 1.6726 x 10-24 gm and the mass of one helium nucleus 4He is 6.6447 x 10-24 gm. What is the mass difference in gm between 4 protons and one helium nucleus? Calculate the ratio of the mass difference to the original mass of the 4 protons as a comparison.
