In a particular x-ray tube, an electron approaches the target moving at 1.10 108 m/s. It slows down on being deflected by a nucleus of the target, emitting a photon of energy 30.0 keV. Ignoring the nuclear recoil, but not relativity, compute the final speed of the electron.
Over a certain region of space, the electric potential is given by: V = 3x^2 - 2xy + xyz, Find the expressions for the x, y, and z components of the electric field over this region
Explain the velocity of two different objects: heavy rock & light feather. 1st, describe what happens when the two objects are dropped on Earth. 2nd, compare this to what happens on the Moon.
A hotel elevator ascends 110 {rm m} with a maximum speed of 4 {rm m/s}. Its acceleration and deceleration both have a magnitude of 1.20 {rm m/s^2}.
