Calculate the mass of a pickup truck travelling at 100.0 km h^-1 and a de Broglie wavelength of 1.24 × 10^-38 m. A)1922 kg B)1134 kg C)2347 kg D)2841 kg E)941.6 kg

Question

Quizplus · Accepted Answer

The de Broglie wavelength formula is λ = h / (mv), where h is Planck's constant (6.626 × 10^-34 m^2 kg/s), m is mass, and v is velocity. Rearranging for mass, m = h / (λv). Converting 100.0 km/h to m/s gives 27.78 m/s. Substituting the values, m = 6.626 × 10^-34 / (1.24 × 10^-38 × 27.78) ≈ 1922 kg.
