D) Neutrinos have a tendency to pass through just about anything without interactions, making them very difficult to detect. The Sun generates energy primarily by nuclear fission. 33. What voltage will he encounter on the input side of the transformer? Sunspots on the surface of the Sun are regions of intense magnetic activity, appearing as dark spots in visible light due to the cooler temperatures found in these regions. Sunspots are dark patches on the surface of the Sun caused by strong concentrations of magnetic fields. 1. C) The chromosphere is the source of X rays, and the corona is the source of radio waves. The corona and chromosphere are hotter than the photosphere. The Sun and Sunspots B. The intricate patterns visible in an X-ray image of the Sun generally show In the late 1800s, Kelvin and Helmholtz suggested that the Sun stayed hot due to gravitational contraction. When the Sun is near solar maximum, it undergoes a much higher rate of violent activity in the form of solar flares. What is the velocity in the duct? Show explanation. B) We did not know how to detect neutrinos. B) Fission reactions in the Sun have ceased. D) orange 4). B) The chromosphere is best observed with ultraviolet telescopes and the corona is best observed with X-ray telescopes. sunspots are brighter than the rest of the How much mass does the Sun lose through nuclear fusion per second? As the cycle ends, it . composition, temperature, and function. The helium produced from the fusion of hydrogen has less mass than the hydrogen that goes into its formation. B E. More solar energy is radiated when sunspots are fewer. Fill in a chart like the one shown here to illustrate key aspects of Thomas's voice. A Laura miraba a Elin con amor. to force it to move in an orbit. A distinct class of gases, particles, and other substances that the EPA has deemed worthy of regulating. 3) What do we mean when we say that the Sun is in gravitational equilibrium? A) Nuclei normally repel because they are all positively charged and can be made to stick only when brought close enough for the strong force to take hold. B) wave motions in the solar interior B) p + p becomes 2H + energy. Which of the following best describes why the Sun emits most of its energy in the form of visible light? They often occur in pairs of opposite magnetic polarity. Magnetism is a physical quality mediated by a magnetic field that refers to the ability to create attracted and repulsive occurrences in other substances. The spectral class of the star Enif is K2 while that of the Sun is, G2.
