- Studying neutrinos helped to explain how our Sun works but led to changes in theories of particle physics. How is this process consistent with the scientific process? How can details about a theory be adjusted without undermining other discoveries made through the theory’s predictions?arrow_forwardHow does the mass of the sun change during its lifetime- does it increase, decrease or stay the same? Explain your answer.arrow_forwardSolar scientists want to measure the temperature inside the sun by sending in probes. Imagine that temperature increases by 1 million◦C for every 10,000 km below the surface. A probe that can handle a temperature of x million degrees costs x³ million dollars. a. How much would it cost to measure the temperature 10,000 km down? b. How much would it cost to measure the temperature 100,000 km down? c.

- Rank the layers of the Sun based on their average temperature, from hottest to coolest. A) Corona B) Radiative Zone C) Convection Zone D) Chromospere E) Core F) Photosphere Answer: Submit All Answers Last Answer: EADBCF Incorrect, ONE try left!!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_forwardOrder the following statements so that they make sense according to star birth stages 1.At this stage, energy moves to the surface primarily through convection. At the end of this stage, the photosphere's temperature can reach 3,000K 2.In this stage, nuclear fusion starts and the energy transport mechanism switches from convection to radiative diffusion 3.In this stage, nuclear fusion rate is high enough to balance out the rate of radiative energy escape the surface 4.During this stage, gravitational contraction causes its luminosity to decrease because the protostar gets smaller while its surface temperature stays the samearrow_forward
