What is the minimum uncertainty in the position of a small particle if it has velocity of 40.0km/s with a 2000. nm/s uncertainty of that velocity, and an accurate mass of 1 pg? What is the wavelength of the small particle? Calculate the energy of a photon (m = 0 kg, A = 6.000 × 10-7 m, c = 2.998 × 108 m/s), a neutron (m = 1.674 × 102 kg, v = 2200 m/s, A = 1.799 x 10-10 m), and 2.000 moles of neutrons (travelling at the same speed as the single neutron). A bar of hot metal is emitting blackbody radiation. The peak wavelength of this radiation is orange. If the photons at this wavelength have an energy of 3.30 x 10-10nJ each, what is the temperature of the metal? • Previous Next
