Imagine an alternate universe where the value of the Planck constant is 6.62607-10-10 J-s. 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 A grain of sand with a mass of 205 mg, 905. um wide, moving at 1.00 mm/s An alpha particle with a mass of 6.6 x 1027 kg. 8.0 x 10 15 m wide, moving at 15. km/s A bacterium with a mass of 10,0 pg, 4.0 um long, moving at 4.00 m/s A turtle with a mass of 940. g. 27, om long, moving at 2.2 im/s quantum or classical?
