While the atmosphere exerts pressure, it is a negligible amount. We can apply our knowledge of how gases behave at different temperatures and densities, which is testable in laboratory environments, to make a mathematical model of the Sun. The source of energy that keeps the Sun shining today is Therefore, in conclusion, sunspots do not make the Earth hotter. Which of the following is not one of the reasons for Earth's seasonality? C) Nuclei have to be very hot in order to fuse, and the only way to get them hot is to bring them close together. Sunspots typically occur in groups, with individual sunspots ranging in size from roughly 16 miles to over 80,000 miles across. C. They can be larger in diameter than Earth. Thus, the observations that confirm this prediction support the theory. they are brighter than the rest of the sun's surfaced. This low density in turn causes the Suns energy to be absorbed unevenly, creating areas on the surface that are cooler than their surroundings. Over time, solar activityand the number of sunspotsincreases. causes lung irritation, asthma, and susceptibility to respiratory illness in humans. They are distributed approximately uniformly over the Sun's surface both in position and in time. two zones that absorb radiation from the Sun. A core temperatures reached at this stage of development is. Modelo A Mara (le-les) encantan las pelculas romnticas. E. The circle of illumination passes through both poles. B) We can make a computer model of the Sun's interior that allow us to predict the observable properties of the Sun. A. Briefly describe the phenomena of the sunspot cycle. a disk-shaped nebula of dust and gas rotating around a relatively. D) our mathematical models of the solar interior are fairly accurate. C a verification of the Doppler equation for wavelength shift of. Which of the following statements about the sunspot cycle is not true This site is using cookies under cookie policy . your choice on the answer sheet. C During a time interval of 1.5 s\mu ss in the rest frame of the muons, half of the muons present at the beginning of the interval decay. Suppose that, for some unknown reason, the core of the Sun suddenly became hotter. Again, this showed that not everything in the heavens revolved around the Earth. a. Space scientists study these to see how they perturb Earth's magnetic fields and affect satellites circling around Earth, but . B) 5 million years. Solar neutrinos coming from the Sun have been detected, but in fewer numbers than predicted by theoretical models. d. sunspots can be up to 12 times larger than earth. and occasionally x rays and visible light. b) Determine how many trucks will be required to complete the job. Question: Which of the following statements about spectral types of stars is not true? INSTRUCTIONS:Fill They exert pressure outward, counterbalancing atmospheric pressure. companion, Too few neutrinos are detected on Earth compared to the number the solar model predicts, The Language of Composition: Reading, Writing, Rhetoric, Lawrence Scanlon, Renee H. Shea, Robin Dissin Aufses. C) collide. D) reabsorbed as molecular hydrogen. is considered beneficial in trapping UV radiation. 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. However, the energy of this light was released by fusion in the Sun's core about 2) When is/was gravitational contraction an important energy-generation mechanism for the Sun? Expert Answer. QUESTION 30 According to the lastest survey estimates, which of the following classes of stars makes up about 8% of all the stars in the universe?
