- If the temperature at the centre of the sun is 15,000,000 K and the temperature of the photosphere is 5,800 K, what is the ratio of the temperature at the centre of the Sun compared to the photosphere? Express your final answer in the fully factorised form x : 1, where x is a number that you should determine to an appropriate number of significant figures and write it using scientific notation.What percentage of the energy we use comes from the sun? 25% 50% More than 90% Less than 10%Fusion only occurs in the solar core. Assuming that 10% of the Sun’s total mass is available to participate in fusion, how long can the Sun continue hydrogen fusion until all available mass is used up? (express your answer in years)
- 08. Matching These are wrong. Please fix. Thank you.Sunspots appear dark because they are A) hotter than the rest of the Sun's surface. B) more magnetic than the rest of the Sun's surface. C) cooler than the rest of the Sun's surface. D) None of the aboveWhat is the source of the Sun's energy? Group of answer choices Gravitational collapse Solar power Heat Nuclear fusion Nuclear fission
