Compton Scattering: A 29.0-pm-wavelength photon is scattered by a stationary electron. What is the maximum energy loss the photon can have? (melectron = 9.11 × 10-31 kg, c = 3.00 × 108 m/s, h = 6.626 × 10-34 J ? s, 1 eV = 1.60 × 10-19 J)
A. 4.0 keV B. 6.1 keV C. 10 keV D. 12 keV E. 15 keV
A 2200-kg auto moving northward at 12.0 m/s runs into a 3800-kg truck which is also moving northward, but at 5.00 m/s. If the vehicles lock bumpers, how fast are they moving just after the collision?
