b. At TR, calculate the number of free electrons (n) per mº for Ag assuming the electron mobility of Ag is; He. Ag = 0.012 m?NV-S c. For the same number of free electrons determined in b., if you were able to purify the Ag material and increase the electron mobility to 0.15 m²N - S, what is the new conductivity of Ag, Ag? Would this conductivity be greater or lesser than for the Ag in b.? LAANI UJ points...

Problem 5 In the image, three very close parallel wires each carrying a current. The magnitude of the current in the first wire I1 = 10 (A) and second wire 12 = 14 (A) and their directions are shown with black arrows in the image. The value of current 1, and its direction are unknown. The magnetic field B due to all three wires at point P which is 4 (m)...

A large number of energetic cosmic-ray particles reach Earth's atmosphere continuously and knock electrons out of the molecules in the air. Once an electron is released, it responds to an electrostatic force that is due to an electric field E produced in the atmosphere by other point charges. Near the surface of Earth, this electric field has a magnitude of |E| = 150 N/C and is directed downward. Calculate the change (in J) in electric potential energy of a released...

Solar power Systems earned $20 per share at the beginning of the year and paid out $10 in dividends to shareholders (so, D0=$10) and retained $10 to invest in new projects with an expected return on equity of 19 percent. In the future, Solarpower expects to retain the same dividend payout ratio, expects to earn return of 19 percent on its equity invested in its new projects, and will not be changing the number of shares of common stock outstanding....
