If Planck's constant were larger than it is,
A)moving bodies would have longer wavelengths.
B)moving bodies would have smaller energies.
C)moving bodies would have higher speeds.
D)the uncertainty principle would be more significant.

The uncertainty principle states that the more precisely the position of a particle is known, the less precisely its momentum can be known, and vice versa. If Planck's constant were larger, the uncertainty in momentum would be greater for a given uncertainty in position. This would mean that moving bodies would have higher speeds, as their momentum would be less precisely known.
