Question 4 4 points save answer the stefan-boltzmann law lets you relate how much energy something is radiating to its temperature (we did this multiple times in class). what is the temperature of the earth if it is radiating the energyout you just calculated? round your answer to the nearest kelvin.

What was the temperature anomaly in buffalo, ny on august 27 , 2019? give your answer in °c. answers within ±3°c of the correct answer are marked correct. the long-term average temperature for august in buffalo is 20 °c. using this information and your answer from q8, what was the temperature in buffalo on august 27, 2019? give your answer in °c. hotter objects emit than cooler objects a. more energy at redder wavelengths b. more energy at bluer wavelengths c. less energy at redder wavelengths d. less energy at bluer wavelengths match the sun and earth with the wavelength of light that it primarily emits. earth sun a. longer wavelength b. shorter wavelength use the graphing tool at to investigate the wavelengths of light that would be emitted by stars of certain temperatures. using this tool, you can adjust the temperature using either by typing the temperature into the white box on the right, or by adjusting the slider underneath the white box. for each star, match it to its peak wavelength. t = 5500 k (the sun) t = 4000 k t = 3,000 k t = 6000 k t = 4700 k a. green b. red c. infrared d. yellow e. blue the average temperature at the earth's surface is 14°c. what is this temperature in kelvin? use your answer from q17 and the stefan-boltzmann equation to calculate how much power each square meter of the earth's surface radiates. give your answer in w/m2. round to the nearest w/m2. in what part of the electromagnetic spectrum does the earth radiate light? answer in a single word (no numbers). consider your answers to the previous three questions. if the surface of the earth is radiating that much energy, why do we not see the ground glowing? answer in 1-2 sentences.
