Explain what physicists mean when they say that the de Broglie wavelength relates to the probability distribution wave function.
1 answer:
Answer:
Because it unites particle and wave nature.
Explanation:
De Broglie wavelength can be defined as the,
Here, h is planks constant, m is the mass of electron, v is the velocity of electron.
Since the de Broglie wavelength can behave like the photon wavelength with respect to the momentum
It unites particles and waves nature ,so De Broglie wavelengths is probability waves associated with the wave function according to physicists.

Answer:
The average velocity of the car is, V = 74.04 m/s
Explanation:
Given data,
The initial velocity of the car, u = 0 m/s
The displacement of the ca, S = 1100 m
The time period of travel, t = 14 s
The velocity of the car at point k, v = 65 m/s
Using the II equation of motion,
S = ut + ½ at²
Substituting the given values,
1100 = 0 + ½ x a x 14²
a = 11.22 m/s²
Using the III equation of motion
v² = u² + 2 as
v = √(2as) (∵ u = 0)
Substituting,
v = √(2 x 11.22 x 1100)
= 157.11 m/s
The average speed of the car,
V = 74.04 m/s
Hence, the average velocity of the car is, V = 74.04 m/s
