An electron-positron pair is produced by a 2.85 MeV photon. What is the kinetic energy of the positron if the kinetic energy of the electron is 1.219 MeV? Use the following Joules-to-electron-Volts conversion 1eV = 1.602 × 10-19 J. The rest mass of an electron is 9.11 × 10-31 kg Please answer in MeV

state the equation that you use
Semiconductor Germanium has a density of 5323 a. cm- and atomic mass of 72.63u. If we assume that Germanium can contribute 1 conducting electron per atom, calculate the maximum number of conducting electrons in a silicon sample of 2cm X 10cm X 10cm. E1, frd = eftew+1E2, ~êr = ()**; Superconductor E3, M05T, = constant; E4, E,0) = 3.54k87c; E5, E,(T) = 1.74E,(0)(1-3)*; E6, critical magnetic field B.(T) = B_(0)(1-). Order of energy of...
