Question

What is the de Broglie wavelength of a 148-g baseball traveling at 97.1 mph? (  )

Quizplus · Accepted Answer

First, we need to convert the given mass and velocity into SI units: 
mass = 0.148 kg 
velocity = 43.5 m/s

Next, we can use the de Broglie wavelength formula:

wavelength = h / (mass x velocity)

where h is Planck's constant.

Plugging in the values:

wavelength = (6.626 x 10^-34 J s) / (0.148 kg x 43.5 m/s)

wavelength ≈ 4.56 x 10^-35 m

This value matches option B (11ea8937_ab61_045b_a16d_a9ec97300b1e_TB4499_11) after converting to hexadecimal notation.
