Question1
1) In a Young’s double-slit experiment that uses electrons, an angle that locates the first-order bright fringes is θA = 2.5 × 10-4 degrees while the magnitude of the electron momentum is pA = 1.2 × 10-22 kg*m/s. With same double slit, what momentum magnitude pB is necessary so that an angle of θB = 5.0 × 10-4 degrees locates the first-order bright fringes? pB =? 2) An electron, travelling at a speed of4.53 × 107 m/s, strikes the target of an X-ray tube. Upon impact, electron decelerates to one-quarter of its original speed, emitting an X-ray in the process. What is wavelength of the X-ray photon?
Question2
On an exo-planet, a 70-kg astronaut steps on a scale and finds that scale reads 246 N. A survival pack is dropped a distance 85 m to the ground. (a) How fast will survival pack be moving just by it hits the ground?
(b) Receive the ratio of this speed with speed of the survival pack if it was dropped on earth.
