A mi padre y a m (nos-te) importan los actores de Hollywood. Day-length decreases from the winter solstice until the vernal equinox, when it begins to increase. Which of the following statements about solar sunspots is NOT true? Magnetism is caused by attraction when two items are brought together or repulsion when two objects are moved apart. Granulation is evidence of what phenomenon? B) Earth's upper atmosphere tends to expand during solar maximum, exerting drag on satellites in low orbits. away C) The Sun's core gradually expands with time, and this expansion means there is more room for energy to be generated and hence increases the Sun's luminosity. D b. The spectral class of the star Enif is K2 while that of the Sun is, G2. Which of the following is not a method astronomers use to determine the physical conditions inside the Sun? Astronomers create mathematical models that use the laws of physics, the Sun's observed composition and mass, and computers to predict internal conditions. E) a million years ago.

Astronomy Hw #19 Flashcards | Quizlet How does the Sun generate energy today? C) The rate of nuclear fusion in the Sun peaks about every 11 years. B) the strong wind that blows sunspots around on the surface of the Sun 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. 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.

A Explain the reasoning that led to our understanding of nuclear energy being the source of the Sun's light. Two of the protons are converted into neutrinos. method of calculating distance on a map. A more modern hypothesis was that the Sun shone through the emission of thermal energy resulting from gravitational contraction, but this could only last for about 25 million years, far less than the age of Earth, before the Sun would have contracted to a point. B) With each subsequent peak in the number of sunspots, the magnetic polarity of the Sun is the reverse of the previous peak. E) magnetic fields lift material from the surface of the Sun, cooling off the material faster. with a precise period of 11.3 years. the BEST answer for each question and, mark The middle of the solar cycle is the solar maximum, or when the Sun has the most sunspots. Which of the following is true of the September equinox? apparent brightness against intrinsic brightness of a group of. C D C) attract each other. They are cooler than the surrounding photosphere of the Sun. A) solar neutrinos C) Our understanding of fusion in the Sun suggested that neutrinos should be destroyed before they arrive at Earth, yet neutrinos were being detected. B ) Again, this showed that not everything in the heavens revolved around the Earth. Line spectra C. Light from sunspots D.
