O A. 11 year solar sunspot cycles change the amount of radiation given off by the Sun.
O B. As the Sun rotates more energy is scattered to space and less is retained on the surface.
O C. Cycles of solar flares and prominences heat and cool the layers below the Sun's surface.
O D. Solar energy is affected by the core output of photons.

- Neutrinos produced in the core of the Sun carry energy to its exterior. Is the mechanism for this energy transport conduction, convection, or radiation?arrow_forwardExplain how we know that the Sun’s energy is not supplied either by chemical burning, as in fires here on Earth, or by gravitational contraction (shrinking).arrow_forwardDescribe how energy makes its way from the nuclear core of the Sun to the atmosphere. Include the name of each layer and how energy moves through the layer.arrow_forward
- Describe the two main ways that energy travels through the Sun.arrow_forwardStarting from the core of the Sun and going outward, the temperature decreases. Yet, above the photosphere, the temperature increases. How can this be?arrow_forwardThe sun has a radius of 6.959 × 108 m and a surface temperature of 5.81 x 10° K. When the sun radiates at a rate of 3.91 x 1026 W and is a perfect emitter. What is the rate of energy emitted per square meter? Stefan-Boltzmann constant is 5.67 x 10-8 J/s-m2 K4 a) 5.6 x 107 W/m2 b) 12.8 x 107 W/m2 c) 6.4 x 107 W/m2 25.6 x 107 W/m2 5.6 x 1017 W/m2arrow_forward
- What fuels the Sun’s enormous energy output? Explain.arrow_forwardThe capture of too few solar neutrinos by Davis in the solar neutrino experiment a. can be explained if the sun is not undergoing thermonuclear fusion of hydrogen in its core. b. indicates that the sun’s core is much cooler than expected. c. indicates that the sun’s core is much hotter than expected. d. indicates that the sun’s core is convective. e. is explained by none of the above.arrow_forwardDescribe the process as a photon (energy) created in the Sun's core makes its way out into space. Make sure to consider the different layers that the photon must pass through to reach the Sun's surface.arrow_forward
- Why does convection develop about 70% of the way from the Sun's center to its surface?arrow_forwardGive proper explanation The surface temperature of the Sun is about 5750 K. What is this temperature on the Fahrenheit scale?arrow_forwardThe surface temperature of the Sun is about 6000K. For this question, assume it is exactly 6000K. Now suppose that the surface temperature of the Sun was 12,000 K, rather than 6,000 K. a) How much more thermal radiation would the Sun emit, compared to its current output? Answer as a whole number, which is the ratio of the new to the old output.arrow_forward
