7Why do sunspots look dark?they are holes in the photosphere through which the cooler interior of the Sun is visibleO they are much cooler than the rest of the surface of the Sun due to changes in the Sun's magnetic fieldO they are patches of the photosphere that burn up, creating ashes that look darkO Sunspots are regions in the upper chromosphere where there is a lot of coronium, which absorbs lightO they are much hotter than the surrounding area, so their emission peaks in UV wavelengths, which our eyes cannot seeсC5O0D"A

If the sun expanded to a radius 5000 times its present radius, what would its average density be (in g/cm3?)
A Crude Analysis: In about 5 billion years, the Sun is going to look a lot different. Our sun is going to turn into a red-giant, a bigger star whose core temperature is much higher than the Sun's current core temperature (you will learn about the red giants in the coming weeks). Assume the core temperature of the red-giant phase of the Sun does not go beyond 100 million degrees. Do you think the temperature is high enough for helium fusion to occur? Note that this question is about helium fusion not hydrogen fusion. How are you going about proving your claim? Question: What temperature in degrees Kelvin must the red-giant sun be at to allow for the helium-helium interactions to take place not considering the Quantum Mechanical effects (i.e. what temperature would allow helium atoms to breach the helium-helium potential wall without help from Quantum Mechanics)? Use wolfram alpha to find the values for the constants. Round your answer to two decimal places. Your answer i [ Select ] 1.47…
