Under appropriate conditions, molybdenum emits X rays that have a characteristis wavelength of 0.711 Angstrom. These X rays are used in diffraction experiments to dtermine the structures of molecules. How fast would an electron have to be moving in order

98. ## Physics

Observing electron interference through an ordinary macroscopic two-slit experiment would be extremely difficult and would require very slowly moving electrons.  (Slow for an electron means < 10^3 m/s.)   How slowly would electrons have to move through

A 1600 kg car moves along a horizontal road at speed v0 = 13.3 m/s. The road is wet, so the static friction coefficient between the tires and the road is only μs = 0.21 and the kinetic friction coefficient is even lower, μk = 0.147. The acceleration of
