- 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.62. Pressure of the Photosphere. The gas pressure of the photosphere changes substantially from its upper levels to its lower levels. Near the top of the photosphere, the temperature is about 4500 K and there are about 1.6 x 1016 gas particles per cubic centimeter. In the middle, the temperature is about 5800 K and there are about 1.0 x 10" gas particles per cubic centimeter. At the bottom of the photosphere, the temperature is about 7000 K and there are about 1.5 × 10" gas particles per cubic centimeter. Use the ideal gas law (Mathematical Insight 14.2) to compare the pressures of each of these layers; explain the reason for the trend that you find. How do these gas pressures compare with Earth's atmospheric pressure at sea level?Use Wien's Law to calculate the peak wavelength of light coming from the Sun. Assume T=5800 K for the surface temperature of the Sun. Wein's displacement law says that the blackbody temperature and peak wavelength multiplied together give a constant of 0.29 cm-K. (K is degrees Kelvin).
- 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.
- Use Stefan's law to calculate how much energy is emitted per unit area by the photosphere of sun 5800-K.The density and temperature in the solar corona are much higher than in the photosphere. (T/F)Explain why the presence of spectral lines of a given element in the solar spectrum tells you that element is present in the sun, but the absence of the lines would not necessarily mean the element is absent from the sun.
