And at minimum you have a minimum number of sunspots, and at maximum, a maximum. stars noticeably above the main sequence. Which of the following conclusions can be drawn about Enif from. A) building mathematical models that use the laws of physics B) observing X-ray images of the solar interior using satellites C) detecting solar neutrinos generated in the Sun's core D) measuring Doppler shifts to observe solar vibrations A) More sunspots indicate increased solar radiation. A computer accessory salesman attempts to convince you to purchase a "solar neutrino" shield for your new computer. Not only is Earth suddenly spinning faste r, but our Sun is getting more active than NASA predicted. E) Nothing; mass-energy is conserved. A) Energy slowly leaks outward through the diffusion of photons that repeatedly bounce off ions and electrons. What would happen to the core of the sun if its temperature rose slightly? rmine the net force on the dam. Only about 1/3 of the expected number of neutrinos is observed. B) Fusion in the Sun's core creates neutrinos. D) radioactive elements such as uranium and plutonium. C) elements in the Sun other than hydrogen and helium The sunspot cycle, a huge effect, was not discovered until 1843 by Samuel Heinrich Schwabe.The German amateur astronomer was looking for a planet inside the orbit of Mercury and made careful daily drawings to track its passage across the face of the Sun. how (or if) their lifetimes depend on mass. We can measure the luminosity that the Sun is producing and therefore determine how much fusion must be going on in its core. a verification of the Doppler equation for wavelength shift of. Finally, we can test our knowledge of nuclear physics and the fusion process in the core using observations of solar neutrinos. D) areas in the corona that allow us to see through to the photosphere Which of the following sequences of stellar spectral classifications. begins to evolve toward the red giant phase? They can produce flares and coronal mass ejections. The ozonosphere is critical to life because it? C) hotter and denser than the surface. A) about 1023 A hot-air home heating system takes 500 ft3/min (cfm) air at 14.7 psia, 65 F into a furnace, heats it to 130 F, and delivers the flow to a square duct 0.5 ft by 0.5 ft at 15 psia. The light radiated from the Sun's surface reaches Earth in about 8 minutes, but the energy of that light was released by fusion in the solar core about B) use hot gas to create a small Sun in a laboratory. E) all of the above. ozone and VOCs. Reset Help deep-ocean trenches 1. What is shown by the small-scale changes in the shading in the figure above? structure, origin, temperature. Prediction of Amplitude of Solar Cycle 25 using Polar - ResearchGate the monitoring of a distant object without physical contact. We also provide a link between extrinsic uncertainty arising in games (e.g. predicted Convection, or the movement of gas or liquid caused by heat transfer, is not a cause of sunspots, but is instead impeded by the strong magnetic fields that cause sunspots. B) Neutrinos are created as a by-product of the proton-proton chain. Sunspots appear and disappear in a cycle that lasts approxi- mately 15 years. answer choices. This reduces the energy reaching the surface, and the spots appear much cooler and darker than their surroundings. The Montreal Protocol C) 600 tons The number of sunspots has been historically linked to the 11-year sunspot cycle, where sunspots peak in intensity approximately every 11 years. B D) the strong force and the electromagnetic force. D) Coronal mass ejections and other activity associated with the sunspot cycle can disrupt radio communications and knock out sensitive electronic equipment. C) The chromosphere and corona are both best studied with visible light. E) They emit light in other wavelengths that we can't see. D) reabsorbed as molecular hydrogen. No, sunspots do not make the Earth hotter. Together, these two factors lead to sunspots appearing darker than the rest of the Sun. B Sunspots are brighter than the rest of the Sun's surface. The cycle then repeats for another 11 years with the magnetic poles of the Sun flipped. Astronomy Hw #19 Flashcards | Quizlet C) electromagnetic force Select only one. E) both C and D, Studies of solar vibrations have revealed that For example, by detecting solar neutrinos we can learn more about the fusion that is going on within the Sun's core. E) Sunspots can produce flares and prominences. forms acid rain A) The Sun is generating much less energy than we think it is. C) The rate of nuclear fusion in the Sun peaks about every 11 years. an extremely regular build-up and decay of the number of. which of the following is not true of sunspots? E) Energy is conserved so while the gas moves up and down, there is no net transport of energy. C) a hundred years ago. luminosity against mass of a group of stars. What proportion of climate scientists has concluded that humans are the primary driver of today's climate warming? Jupiter's moons The planet Jupiter was accompanied by four tiny satellites which moved around it. A) The core would cool off and continue to shrink as its density increased. D A magnet is an item with magnetic qualities. Which of the following is NOT a correct statement about sunspots? true or false: sunspots appear dark because they are hotter than the surrounding gas of the photosphere. D) 6 H 1 He + energy. The overall fusion reaction by which the Sun currently produces energy is an irregular cycle averaging about 11 years, but sometimes, c. the movement of sunspots on the sun's surface. established a framework to address acid precipitation. Inside the Sun, this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps, these protons fuse together and are turned into helium.So all A,B,C are produced in nuclear fusion in the sun. Choose If the solar core were to increase in temperature, the nuclear fusion rate would soar, generating excess energy that increases the pressure and pushes the core outwards. sunspots are brighter than the rest of the Magnetism is caused by attraction when two items are brought together or repulsion when two objects are moved apart. 31)Option - C is . B) Both processes involve nuclear fusion, but the Sun fuses hydrogen while nuclear power plants fuse uranium. causes lung irritation, asthma, and susceptibility to respiratory illness in humans. Higher-mass stars run through their lives faster and have shorter, b. These are now known as the Galilean moons: Io, Ganymede, Europa and Callisto. List at least two ways the sunspot cycle affects us on Earth. D) use computer models to predict interior conditions. A repairman climbs the pole. D) convection zone A) As the Sun was forming, nuclear fusion reactions in the shrinking clouds of gas slowly became stronger and stronger, until the Sun reached its current luminosity. And the cycle is 11 years, so in the next few years we'll be seeing more sunspots. Which of the following can be used to determine the temperature of a Almost all elements heavier than hydrogen and helium were made inside stars. D E Sunspots can produce flares and prominences. Which the following is not true of sunspots? A) 600 million tons very young, because the G and K stars are still evolving towards, b. with a precise period of 11.3 years. You will then enter this convective layer, feeling regions of hot plasma rising upward to meet you and seeing cooler gas descending from the surface.
