When a fast electron (i.e., one moving at a relativistic speed) passes by a heavy atom, it interacts with the atom's electric field. As a result, the electron's kinetic energy is reduced; the electron slows down. In the meantime, a photon of light is emitted. The kinetic energy lost by the electron equals the energy E., of a photon of radiated light: E,= K-K', where K and K' are the kinetic energies of the electron before and after radiation, respectively. This kind of radiation is called bremsstrahlung radiation, which in German means "braking radiation" or "deceleration radiation." The highest energy of a radiated photon corresponds to the moment when the electron is completely stopped. ▼ Part A Given an electron beam whose electrons have kinetic energy of 9.00 keV, what is the minimum wavelength Lambdamin of light radiated by such beam directed head-on into a lead wall? Express your answer numerically in nanometers.
For a skateboard with a negative acceleration, which of the following statements is always true? 1. The initial velocity of the skateboard will be greater than it’s final velocity. 2. The skateboard will have a negative displacement. 3. The final velocity of the skateboard will be positive. 4. The final velocity of the skateboard will be negative 5. The skateboard is losing speed

An object of mass M = 2.00 kg is attached to a spring with spring constant k = 550 N/m whose unstretched length is L = 0.140 m , and whose far end is fixed to a shaft that is rotating with an angular speed of ω = 5.00 radians/s . Neglect gravity and assume that the mass also rotates with an angular speed of 5.00 radians/s as shown. Given the angular speed of ω = 5.00 radians/s , find the radius R(ω) at which the mass rotates without moving toward or away from the origin.
