Why does nuclear fusion only take place in the Sun’s core?
Which of the following layers of the Sun can be seen with some type of telescope? Consider all forms of light, but do not consider neutrinos or other particles. (Give ALL correct answers in alphabetical order, i.e., B, AC, BCD...)A) Corona.B) Photosphere.C) Radiation Zone.D) Chromosphere.E) Convection Zone.F) Core.
Assume that Hydrogen comprises 79% of the Sun's mass. How much mass is this? 1.57e+30 kg
Only about 11% of the initial Hydrogen in the Sun is in the core where it is hot enough to burn. What was the total mass of the inital H in the core of the Sun?
Hint: Use the answer above and the percent in the core to determine the total mass.
Using the results from above, how much total energy is available to the Sun via nuclear fusion over its lifetime? (HINT: only 0.71% of the total mass of the available H in the core is converted into energy)
Hint: E = m c^2

- What do measurements of the number of neutrinos emitted by the Sun tell us about conditions deep in the solar interior?arrow_forwardNow suppose that all of the hydrogen atoms in the Sun were converted into helium. How much total energy would be produced? (To calculate the answer, you will have to estimate how many hydrogen atoms are in the Sun. This will give you good practice with scientific notation, since the numbers involved are very large! See Appendix C for a review of scientific notation.)arrow_forwardWhich aspects of the Sun’s activity cycle have a period of about 11 years? Which vary during intervals of about 22 years?arrow_forward

Answer in years.arrow_forward1. 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's initial supply of hydrogen can last. Give your answer in both seconds and years. Hint: use the result 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?arrow_forward

- The average density of the sun is 1. 4 g/cm3 What do you expect the density to be at 0.25 of Rsun? 2) The average density of the sun is 1.4 g/cm3. The following resource claims that the sun's core has a density of 150 g/cm3 and a radius of 25% of the sun's radius. Assume the core has a constant density and calculate it's mass. What fraction of the sun's mass is in the core according to that resource?arrow_forwardThe surface temperature of the Sun is about 6000K. For this question, assume it is exactly 6000K. Now suppose that the surface temperature of the Sun was 12,000 K, rather than 6,000 K. a) How much more thermal radiation would the Sun emit, compared to its current output? Answer as a whole number, which is the ratio of the new to the old output.arrow_forwardThe Sun is estimated to have about 5.00 billion years left in it’s “normal” (main sequence) lifetime.
