The cosmic background radiation permeating the universe has the spectrum of a 2.7-K blackbody radiator. What is the peak wavelength of this radiation? The constant in Wien's law is 0.0029 m ∙ K. Hint: the answer will be in mm
10 marks] Question 10 [2 2 2 2 2 The Cosmic Microwave Background (CMB) is blackbody radiation remaining from an hot phase in the universe, and currently has a temperature of 2.7K. First we will determine the current number density of CMB photons. early (a) What is the current energy density of the CMB? (b) What is the average energy of a single photon in the CMB today (at the peak of the blackbody curve)? (c) If we take this...
Cosmic background radiation. The following figure shows measurements of the energy density of the background cosmic radiation. The graphical quantity is the spectral density as a function of the energy per unit volume according to the relationship: di / dw = cu(w) / 41 Assuming Planck's Law, estimate the temperature of the background cosmic radiation. Use that lerg = 10-7 J, kg = 1.38 x 10-23 J/K y c~ 10%m/s. -3.00 30 Wavelength (cm) 0.3 0.03 10-14 10-15 10-16 10-17...
Please help me, I wasn't sure which test to use so I did both of them on excel. Please let me know which is correct and answer A-C. I will give the answer a thumbs up if you can get back to me asap. The physicians also believe that people who are obese are more likely to die earlier than those who are not. Again use the data in the Framingham sample to test this theory by comparing the mean...
Please use the formulate sheet and show all steps to make sure the question is worth any points a) The initial ratio of deuterium (D) to hydrogen (H) in a planet's atmosphere was 175000; however, the present ratio is 1/1500 and the initial and final abundances of D are 5 x 10° atoms per m3 and 9 x 106 atoms per m2, respectively. What fraction of deuterium has been lost, and what fraction of hydrogen has been lost in this...
