Question

Quizplus · Accepted Answer

The wavelength (λ) of an object is given by λ = h/mv, where h is the Planck's constant, m is the mass of the object, and v is the velocity of the object.
Plugging in the given values, we get:
λ = (6.626 x 10^-34 m^2 kg s^-1)/(0.155 kg x 32.5 m s^-1) 
λ = 1.32 x 10^-34 m
Therefore, the best choice is B.
