E) Energy is conserved so while the gas moves up and down, there is no net transport of energy. a. D) Neutrinos have a tendency to pass through just about anything without interactions, making them very difficult to detect. What problem have observers of solar neutrinos run into? C) The Sun's mass is about 300,000 times the mass of Earth. (D). b. C) The radiation produced by fusion reactions that is trapped in the core gradually raises the temperature, increasing the rate of fusion. B. Chlorine freed from CFCs only remain in the atmosphere for several days, on average. A) The Sun rotates faster at its poles. *b. D) trillions of degrees. SVSU GEOG101! Chapter 1 Flashcards | Quizlet Briefly describe what you will see as you descend. C) magnetic fields trap ionized gases that absorb light. predicted What happens to the positron? Sunspots can have dramatic effects on the Earths space environment, including the generation of coronal mass ejections, solar flares, and other space weather phenomena. B This cluster is, *a. 10. a somewhat irregular but always present cycle of build-up and, d. on the answer sheet. indication of what physical process at work in the Sun? the monitoring of a distant object without physical contact. The first step was measuring the distance to the Sun which then allowed us to calculate how luminous it is and therefore how much energy is needed to power it. A) The Sun generates energy by fusing small nuclei into larger ones, while our power plants generate energy by the fission (splitting) of large nuclei. 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. A protostar of about 1 solar mass is gradually contracting and, becoming D) They are thick clouds on the sun, blocking its light. Solely anthropogenic gases, particles, and other substances in amounts that cause damage to the environment or are harmful to humans. A. the revolution of Earth around the Sun B) 3 He 1 C + energy. A) They have a tendency to pass through just about any material without any interactions. old, because the G and K stars are already evolving off (away, c. D) The Sun generates energy through fission while nuclear power plants generate energy through fusion. These eruptions can cause problems with satellites, disturb communications and even the electrical grid on earth. A) several thousand years ago. If the Sun suddenly stopped emitting neutrinos, what might we infer (after checking that our neutrino detectors were still operational)? Sunspots are dark, planet-size regions of strong magnetic fields on the surface of the sun. A pulsating white dwarf star, fluctuating rapidly in brightness. Hundreds of lakes are incapable of supporting life due to high acidity. E. It results from chemical reactions with chlorine derived from CFCs. C) This process could not possibly lead to the observed power output of the Sun. the monitoring of a distant object without physical contact. A) at the same temperature and density as the surface. has a charge of +2. b. Sunspots may also be caused by changes in the Suns rotation, which can cause its poles to move, creating changes in the magnetic field and sunspot activity. question E) green. Which of the following statements about the sunspot - Course Hero Which is the correct sequence for the following end-points of. Sunspots are areas on the surface of the Sun that appear darker than their surrounding regions. B It results from chemical reactions with chlorine derived from CFCs. Hydrogen fusion in the Sun requires a temperature (in Kelvin) of. D) about 14 billion light years (the size of the observable universe) The "star" appears to move in a straight line against a, a. Why do you turn down this excellent offer? C) extremely hot plasma flowing along magnetic field lines. They often occur in pairs of opposite magnetic polarity. Which of the following is true regarding acid deposition? Today, it far exceeds its natural range of 180 to 300 ppm. luminosity against mass of a group of stars. 1. They are cooler than the surrounding photosphere of the Sun. The gravitational disturbance of one star's motion by its. C) They are extremely hot and emit all their radiation as X rays rather than visible light. C. It decreases to 1/4 its original magnitude. C is affecting the stratospheric ozone concentration. They exert pressure outward, counterbalancing atmospheric pressure. B) p + p becomes 2H + energy. Why do the tropics have a positive net radiation while the poles have a negative value? A. Lower-mass stars run through their lives faster and have shorter. B) It is the primary energy generation mechanism in the Sun today. a. D) orange It is true. D. It decreases to 1/2 its original magnitude. They can produce flares and coronal mass ejections. D) We can study solar neutrinos. Sunspots are dark patches on the surface of the Sun caused by strong concentrations of magnetic fields. The Sun | Earth Sciences Quiz - Quizizz B) 100% hydrogen and helium While the quality of observations was good, consistent observation was lacking. D. It results from the burning of fossil fuels. They are magnetic storms. Abe Mizrahi, Edward E. Prather, Gina Brissenden, Jeff P. Adams, Jeffrey O. Bennett, Mark Voit, Megan O. Donahue, Nicholas O. Schneider, Foundations of Astronomy plus The Night Sky Planisphere - Latitude 30- 40, Chapter 14 Fire Detection and Alarm Systems,. a mixture of gases that behaves like single gas. the difference in amount of incoming shortwave and outgoing longwave radiation. A) 3 H 1 Li + energy. B) They are regions that are significantly cooler than the rest of the photosphere. C. The depletion is restricted to the arctic and antarctic regions. An ice storm breaks a transmission line and interrupts electric power to a town. Which statement best describes the solar neutrino problem?
