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...

FAO Figure 1 2. A thin wire of length L has a uniform charge density +1.A cylindrical Gaussian surface of radius d is drawn with the wire along its central axis, as shown above. Point P is located at the center of one end of the cylinder, a distance d from the end of the wire. Point Q is on the edge of the cylinder directly above the center of the wire, as shown above. A student says, "Gauss's law...

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...
