Part A
By measuring the spectrum of wavelengths of light from a star, we know that its surface temperature is 5800 K. By measuring the rate at which we receive its energy on earth, we know
that it is radiating a total of 3.98x1026 J/s and behaves nearly like an ideal blackbody. Use this information to calculate the diameter of the star.
