I am just trying to understand how to do this problem.

3. Relationships between temperature, energy, and EM radiation: You are enjoying a campre and decide to measure how much energy it is giving off. You nd that the heat flux is 1x105 WIN. a) Calculate the temperature of the re using Stefan-Boltzmann Law. Give your answer in Wm Eahmhgit, and be sure to show your work! [4] b) Using the temperature calculated in the previous problem, calculate the peak wavelength of the radiation being emitted by the fire using Wien's Law. [4] c) What type of radiation is emitted at the peak wavelength for the fire? [2] d) Explain why the fire is visible despite the fact that the peak wavelength is in the infrared range. [2] e) By what factor is the re hotter compared to the average surface temperature of the Earth (288K)? [2] f) By what factor is the heat flux emitted by the re greater than that emitted by the Earth? Calculate this using the relationship found in the previous exercise and the proportionality of heat flux and temperature [4] g) What is ratio of the peak wavelength of the fire (calculated in #4) to that of the Earth? Use the temperature ratio calculated in #7t [4]
