A) The number of sunspots peaks approximately every 11 years. ~ Very strong energy source production ofjets formed in isolated areas varies on extremely long timescales strong radio source 1/ point 1/ point 1/ point. What stops the Sun from collapsing under the force of its own, *a. (C). B) the Sun is made of atoms and molecules. Two of the protons are converted into neutrinos. A) Gravitational contraction involves nuclear fusion, which generates a lot of heat. D) They are thick clouds on the sun, blocking its light. They are distributed approximately uniformly over the Sun's surface both in position and in time. GEOG 1112 - Chapter 3: (Questions)Earth's Atm, GEOG 1112k- Chapter 9: Climate Classification. Right now, about half the amount of hydrogen in the core of the Sun has been fused into helium. Which of the following observations would NOT be an indication of a, a. then 4) What two forces are balanced in what we call gravitational equilibrium? Solved Which of the following is TRUE? Sunspots are more | Chegg.com A. After observing the Earth's weather patterns and the 11-year sunspot Sunspots have a temperature that is about 1,500C cooler than the temperature of the rest of the suns surface. mostly carbon dioxide and water vapor. is lost from the atom, and energy is equivalent to mass, c. Yes, sunspots are an indication of increased activity on the Suns surface. Satellites in low-Earth orbits are more likely to crash to Earth when the sunspot cycle is near solar maximum because The sun's atmosphere: Photosphere, chromosphere and corona Elin la miraba con amor tambin. The ESSAY. Question 4 options: They are holes where we can see into the the interior of the Sun. b. The "star" appears to move in a straight line against a, a. a measurement of the surface temperatures of stars. A) 600 million tons Briefly explain why sunspots are cooler than surrounding regions of the Sun and why they look dark in photos. , A new embankment, when completed will occupy a net volume of 257,000cy. A. Atmospheric pressure increases with altitude and is, therefore, lowest near the Earth's surface. A) one year ago. B) The chromosphere is the source of infrared light, and the corona is the source of ultraviolet light. Which of the following is not true of sunspots? Which of the following statements about solar sunspots is not true D) Both have approximately the same mass. C C) small variations in the rate of nuclear energy generation in the solar interior C) Heat is generated when gravity contracts, because gravity is an inverse square law force. D) only by using sophisticated computer models, because there are no observational ways of measuring magnetic field strength. 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. A) The Sun becomes much brighter. Which part of the Hertzsprung-Russell diagram is occupied by, c. They gradually shrink to the size of the Earth. 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. 5) Which of the following statements about the sunspot cycle isnottrue? Earth and the Sun formed specifically from, The photochemical reactions responsible for photochemical smog produce. Similarly if the solar core were to decrease in temperature, the nuclear fusion rate would plummet and gravity would overcome thermal pressure and contract the core. How is the sunspot cycle directly relevant to us here on Earth? B) regions in the photosphere where magnetic lines gather, creating cooler areas with much less plasma The dark spots are caused by regions of intense magnetic field, which are up to 2,500 times greater than the field of the earth. All radio signals pass through this region virtually unaffected. If the Sun suddenly stopped emitting neutrinos, what might we infer (after checking that our neutrino detectors were still operational)? companion, correlated equilibria) and extrinsic uncertainty in market economies (e.g. sunspots are brighter than the rest of the sun's surface. When the Sun is near solar maximum, it undergoes a much higher rate of violent activity in the form of solar flares. The Sun has sufficient hydrogen to continue fusing into helium for how much longer? luminosity against mass of a group of stars. finally What is the only force that can overcome the repulsion between two positively charged nuclei to bind them into an atomic nucleus? However, some energy is released from the upper layers of the solar atmosphere. The sun emits radiant energy composed of, 11. The people living at 40 N or S experience about six-hours difference in daylength from winter to summer. B Briefly describe why the fact that we detect neutrinos coming from the Sun supports the idea that the Sun generates energy by nuclear fusion. The specific type of fusion that occurs inside of the Sun is known as proton-proton fusion. which of the following is not true of sunspots? which of the following How do we know what goes on under the surface of the Sun? type of satellite used for monitoring the Earth's surface. D) our mathematical models of the solar interior are fairly accurate. 1) In the late 1800s, Kelvin and Helmholtz suggested that the Sun stayed hot thanks to gravitational contraction. Most choices will fit grammatically and will even make sense logically, but you must choose the pair that best fits the idea of the sentence. Day-length decreases from the winter solstice until the vernal equinox, when it begins to increase. C B) Energy is produced in the convection zone by nuclear fusion. E) Radio waves can pass directly through the gas which allows us to see the core. 10. *b. The Sun will exhaust its nuclear fuel in about they C. The region principally absorbs gamma rays, X-rays, and interacts with the solar wind. c) Determine how many gallons of water will need to be added to each truck. The Sun Is Now More Active Than NASA Predicted. It Could Be In Its They move along with the Suns active region and can measure up to 50,000 miles across. A) The number of sunspots peaks approximately every 11 years. C) Energy is transported outward by the rising of hot plasma and the sinking of cooler plasma. E. The equator always receives equal hours of day and night. For example, by detecting solar neutrinos we can learn more about the fusion that is going on within the Sun's core. C) corona. Space weather: What is it and how is it predicted? | Space D What is the evidence for the heliocentric model (sun is the center of the solar system) and evidence why the Geocentric model (the universe revolves around the earth) is wrong? While the atmosphere exerts pressure, it is a negligible amount. The neutrinos are of the wrong type (muon neutrinos, instead of.
