Imagine an alternate universe where the value of the planck constant is 6.62607x10^-9·js . in that universe, which of the following objects would require quantum mechanics to describe, that is, would show both particle and wave properties? which objects would act like everyday objects, and be adequately described by classical mechanics? object quantum or classical? a bacterium with a mass of 7.0 pg, 1.0 µm long, moving at 2.00 µm/s. classical quantum an iceberg with a mass of 2.2 x 108 kg, 60. m wide, moving at 0.96 km/h. classical quantum a paper airplane with a mass of 4.1 g, 165. mm long, moving at 2.9 m/s. classical quantum an alpha particle with a mass of 6.6 x 10-27 kg, 8.0 x 10-15 m wide, moving at 15. km/s. classical quantum clears your work. undoes your last action. provides information about entering answers.
