What is the de Broglie wavelength associated with a 1000-kg car moving at 25 m/s?
Answer to relevant QuestionsA scientist wants to use an electron microscope to observe details on the order of 0.25 nm.

If an excited state of an atom has a lifetime of 2.0 x 10-7 s, what is the minimum error associated with the measurement of the energy of this state? (a) The minimum photon energy to create a proton–antiproton pair is (1) more than, (2) the same as, or (3) less than the minimum photon energy to create a neutron–antineutron pair. Explain.
