the movement of sunspots on the sun's surface. Which of the following is true with respect to the. The overall result of the proton-proton chain is Determine the distance traveled a B) The likelihood of seeing solar prominences or solar flares is higher when sunspots are more common and lower when they are less common. B) Nuclei are attracted to each other by the electromagnetic force, but this force is only strong enough to make nuclei stick when they are very close together. The magnetic fields underlying sunspots are believed to be generated by the suns rotation, which causes a dynamo effect and creates the intense magnetic fields. Two of the protons are ejected back into the solar material. If they were hotter then they would be brighter since, by the blackbody law, Luminosity is proportional to Temperature 4. Sunspots can appear in both the northern and southern hemispheres of the Sun, and usually occur in pairs of opposite magnetic polarity. B A) about one meter B) joules D) The chromosphere and corona are both best studied with radio telescopes. D) The higher temperature would not affect the fusion rate but would cause the core to expand and cool until the temperature returned to normal, with the core at a new, slightly larger size. C) 10,000 years C C) elements in the Sun other than hydrogen and helium B. D) constantly rising to the surface through convection. 6. b. Most of the energy produced in the Sun is released in the form of visible light from the photosphere. A) They have a tendency to pass through just about any material without any interactions. E) The term solar neutrino problem refers to the fact that neutrinos are extremely difficult to detect. d. A) It predicted that the Sun would shrink noticeably as we watched it, but the Sun appears to be stable in size. They are distributed approximately uniformly over the Sun's surface both in position and in time. E) The mass of a neutrino is 30 percent of the mass of an electron. A rapidly rotating neutron star, producing beams of radio energy. B) It referred to the fact that neutrinos are extremely difficult to detect. Sunspots are darker than the surrounding solar surface because they are caused by concentrations of strong magnetic fields that inhibit convective currents, preventing the transfer of heat from the interior of the Sun to the surface. Main sequence stars all have approximately the same mass, by, 25. the parallel that is the farthest northern location for the subsolar point during the year. Solved Which one of the following is NOT true? (A) The - Chegg D) kilograms. What was the major drawback of this idea? Sunspots are more important to global warming than GHGs There is more methane in the atmosphere than carbon dioxide Arctic Greening will absorb most of the carbon we emit to the atmosphere Greenhouse gases are by far the largest contributor to modern global warming Volcanic explosions can cool Earth's climate for hundreds of years. the monitoring of a distant object without physical contact. A Astronomy Hw #19 Flashcards | Quizlet *c. They occur in regions of lower-than-average magnetic fields. What would happen to the core of the sun if its temperature rose slightly? D D) The Sun becomes much brighter. Solely natural gases, particles, and other substances in amounts that cause damage to the environment or are harmful to humans. Which of the following regarding atmospheric pressure is true? a. A) The sunspot cycle is very steady, so that each 11-year cycle is nearly identical to every other 11-year cycle.
