The net force on a car traveling at a constant speed in a straight line is zero. In which of these would the net force remain ze
dexar [7]
I believe the answer is <span>In an instant the car comes to a complete stop. 

The net force is calculated through:
F = m x a
m = mass
a = Acceleration

When the car came into a complete stop, the acceleration become 0

Which means that


F = m x a

F = m x 0

F= 0 </span>

What physical meaning is attributed to ψ², the square of the wave function?
Zigmanuir [339]

Answer:

The probability density (ψ2)

Explanation:

Indicates the probability of finding the electron in a certain region of space when it is squared ψ2.

This means that define2 defines the distribution of electronic density around the nucleus in three-dimensional space; a high density represents a high probability of locating the electron and vice versa.

The atomic orbital, can be considered as the electron wave function of an atom.

APPLICATIONS:

1.- Specify the possible energy states that the electron of the hydrogen atom can occupy and identify the corresponding wave functions medio, by means of a set of quantum numbers, with which an understandable model of the hydrogen atom can be constructed.

2.- It does not work for atoms that have more than one electron, but the problem is solved using approximation methods for polyelectronic atoms.
