and a value of gA of 0.009x10-8 and 12x10-8, respectively. What is the most intense line for T=2000k, and T=5000K? At what temperature do the two lines have the same intensity?

Some fussing with Planck's constant, and the energies and wavelengths given suggests a small error in the numbers -- the product of wavelength and voltage should be 1.2398E-6, and the numbers presented are close but don't match exactly. I have not previously encountered gA. You can calculate the strength of blackbody radiation at the given temperatures and wavelengths using Planck distribution and the gas constant; I'd guess that if you adjust the strengths by the given gA and run the computation backwards, that would give you the temperature in question.
