Question

Imagine an alternate universe where the value of the Planck constant is 6.62607 x 1039 J. 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? An atom with a mass of 1.0 x 10-27 kg, 193. pm wide, moving at 315. m/s. O classical O quantum A paper airplane with a mass of 4.3 9, 180. mm long, moving at 2.9 m/s. O classical O quantum An airplane with a mass of 1.50 x 104 kg, 16.0 m long, moving at 900. km/h. O classical O quantum A virus with a mass of 5.6 x 10-17 g, 200. nm wide, moving at 2.00 pm/s. O classical O quantum
