Question

Quizplus · Accepted Answer

The de Broglie wavelength is given by the formula λ = h/p, where h is Planck's constant and p is the momentum of the object. The momentum is given by p = mv, where m is the mass and v is the velocity. Substituting the given values, we get:
p = (0.125 kg) × (90 m/s) = 11.25 kg m/s
λ = h/p = (6.626 × 10^-34 J s)/(11.25 kg m/s) = 5.9 × 10^-35 m, which is closest to choice C.
