Answer:

The aufbau principle

The Pauli exclusion principle

Hund's rule of maximum multiplicity

Explanation:

The aufbau principle:

The fundamental electronic configuration is achieved by placing the electrons one by one in the different orbitals available for the atom, which are arranged in increasing order of energy.

The Pauli exclusion principle:

Two electrons of the same atom cannot have their four equal quantum numbers. Because each orbital is defined by the quantum numbers n, l, and m, there are only two possibilities ms = -1/2 and ms = +1/2, which physically reflects that each orbital can contain a maximum of two electrons, having opposite spins

Hund's rule of maximum multiplicity:

This rule says that when there are several electrons occupying degenerate orbitals, of equal energy, they will do so in different orbitals and with parallel spins, whenever this is possible. Because electrons repel each other, the minimum energy configuration is one that has electrons as far away as possible from each other, and that is why they are distributed separately before two electrons occupy the same orbital.

The net electric flux through an octahedron is -1850 N⋅m2/C . Part A How much charge is enclosed within the octahedron? Express

Masteriza [31]

The electric flow is defined as the change of the charge in relation to the constant of the vacuum permittivity constant.

That is to say that mathematically this expression could be given as

$\Phi = \frac{q}{\epsilon_0}$

Here,

$\Phi$ = Electric Flux

q = Charge

$\epsilon_0$ = Vacuum Permittivity

Replacing with our values and solving to find q, we have,

$-1850N\cdot m^2/C = \frac{q}{8.854*10^{-12} C\cdot N^{-1} \cdot m^{-2}}$

$q = - 1.63799*10^{-8}C$

Therefore the charge is enclose within the octahedron with a charge of $- 1.63799*10^{-8}C$

Which of the following statements best summarizes the first paragraph of this passage?

Fed [463]

Read the paragraph multiple times and find the main ideas and supporting details. Find what it is mostly about and compare the information you have to the statements and select the one most like yours. This is the best I can do without seeing any of the choices and the paragraph. Hope this helps! :)

The position function x (6.0 m) cos[(3p rad/s)t p/3 rad]gives the simple harmonic motionof a body. at t 2.0 s, what are the(a) d

Daniel [21]

The correct formula for this simple harmonic motion is:

x = (6.0) cos [ (3 pi) t + pi/3 ]

A. Calculating for displacement x at t = 2:

x =6.0 cos (19/3 pi)
x = 6 (0.5)

x = 3 m

B. Velocity is equivalent to the 1st derivative of the equation. v = dx / dt

Velocity v = dx/dt = -18 pi sin (3pi t + pi/3)

v = - 18 pi sin (6pi + pi/3)

v = 49.0 m/s

C. Acceleration is the 2nd derivative or the 1st derivative of velocity dv / dt
Acceleration a = dv/dt = -54 pi^2 cos(3pi t + pi/3)

a = -54 pi^2 cos(3pi * 2 + pi/3)

a = 386.34 m/s^2

D. Phase = pi/3

E. frequency f= 3pi/2pi = 1.5Hz

F. period = 1/f = 1/1.5 = .6667sec
