Why does the Sun not collapse under its enormous weight?
a) The Sun is about 4.6 billion years old. If it could have collapsed by now , it would have.
b) Because the Sun is in hydrostatic equilibrium.
c) Because the Sun is not in hydrostatic equilibrium.
d)More than one of the above.
1) What is thermal equilibrium? Is the Sun in thermal equilibrium? How do we know this?
2) In order to maintain thermal equilibrium, how much energy must the Sun generate every second?
The Sun fuses about 600 billion kilograms of hydrogen each second. Based on your result from part A, calculate how long the Sun’s initial supply of hydrogen can last. Give your answer in both seconds and years.

- The Sun is much larger and more massive than Earth. Do you think the average density of the Sun is larger or smaller than that of Earth? Write down your answer before you look up the densities. Now find the values of the densities elsewhere in this text. Were you right? Explain clearly the meanings of density and mass.arrow_forwardEarth contains radioactive elements whose decay produces neutrinos. How might we use neutrinos to determine how these elements are distributed in Earth’s interior?arrow_forwardWhat is the name of the specific nuclear fusion process that dominates energy production in the core of the Sun and gives a brief description of how it works. What I'm looking for in this description is what is the basic premise behind nuclear fusion and what is going into this specific fusion reaction and what comes out of it.arrow_forward

How much greater is this than g at the surface of Earth? Calculate what you would weigh on the surface of the Sun. Your weight would be your Earth weight multiplied by the ratio of the acceleration of gravity on the Sun to the acceleration of gravity on Earth. (Okay, we know that the Sun does not have a solid surface to stand on and that you would be vaporized if you were at the Sun’s photosphere. Humor us for the sake of doing these calculations.)arrow_forwardAssume 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^2arrow_forward
