A:
Q: Use Stefan's law to calculate how much less energy is emitted per unit area of a 4500-K sunspot.
A: Sunspots are large dark regions formed on the Sun's photosphere. They are formed due to magnetic…
Q: how many times more energy is emitted in 1 second from a square meter of the photosphere compared to…
A: According to Stephen Boltzmann law E = σT4 (J/s/m2) where σ is a proportionality constant equal to…
Q: Meridional is derived from meridian. Look up the definition of meridian; what is the direction of…
A: Meridian are the imaginary longitudinal lines across the earth from north pole to the south pole
Q: why isnt there a single convection cell in each hemisphere?
A: Because more solar energy hits the equator, the air warms and forms a low pressure zone. If the…

- Use Wein's law to determine the wavelength corresponding to the peak of the black body curve (a) in the core of the Sun, where the temperature is 10^7, (b) in the solar convection zone (10^5), and (c) just below the solar photosphere (10^4K). What form (visible, infrared, X-ray, etc.) does radiation take in each case?What evidence can you give that the corona has a very high temperature?Describe how a convection current works. In a simple way.
