Quantum numbers are:
(A) n = 1 ⇒ n -1(B) n = 2 ⇒ n = 2What do we mean by quantum numbers?Quantum numbers are used in quantum physics and chemistry to describe the values of conserved quantities in the dynamics of a quantum system. Quantum numbers are eigenvalues of operators that commute with the Hamiltonian and their corresponding eigenspaces—quantities that can be known with precision at the same time as the system's energy. A specification of all of the quantum numbers of a quantum system, when combined, fully characterizes the system's basis state and can, in theory, be measured together.Quantum numbers:
(A) n = 1
The electron in a hydrogen atom with n=1 is in its ground state; if the electron is in the n=2 orbital, it is in an excited state. For a given n value, the total number of orbitals is n2. Angular Momentum (Secondary, Azimunthal) l = 0,..., n-1 Quantum Number(B) n = 2
The n = 2 states begin to fill up as we move to larger atoms, adding electrons one at a time. Because there are four different values for (l, m), each with two allowed spin states, the n = 2 states can hold up to eight electrons. The n = 2 shell includes all states with a quantum number of n = 2.Therefore, Quantum numbers are:

The figure shows a diver diving from a platform. The diver reaches a depth of 4 meters. What is the change in elevation of the diver?
The change in the elevation of the diver is meter(s).
Sorry ik the pic is blurry
The diver's elevation changes by 15 meters.
The diver is initially stopped at a height of 11 meters.
After that, he leaps, falling 11 meters, causing an initial elevation drop of 11 meters.
Finally, he descends to a depth of 4 meters, or 4 meters below the surface of the water, adding 4 more meters to the elevation change (11 + 4 = 15).
The angle of elevation is the angle created between the line of sight and the horizontal. The angle created is an angle of elevation if the line of sight is upward from the horizontal line.
You may calculate the angle of elevation, for instance, by standing on the ground and looking up at the peak of a mountain. For instance, you can determine the angle of elevation by standing on the ground and gazing up at a mountain's peak.
Therefore, making the diver's elevation change 15 meters.

a. the equation of the formula in terms of x is: x = (c - b)/a
b. x = 4 and x = 6
How to Solve an Equation?Where we have a, b, and c as constants of the equation, ax + b = c, and the variable is x, we can solve for the value of x as shown below:
ax + b = c
Subtract b from both sides
ax - b = c - b
ax = c - b
Divide both sides by a
ax/a = c/a - b/a
x = c/a - b/a
x = (c - b)/a
b. 3x + 7 = 19
a = 3, b = 7, and c = 19
Substitute a = 3, b = 7, and c = 19 into x = (c - b)/a
x = (19 - 7)/3
x = (12)/3
x = 4
x - 1 = 5
a = 1, b = -1, and c = 5
Substitute a = 1, b = -1, and c = 5 into x = (c - b)/a
x = (5 - (-1))/1
x = 6/1
x = 6
In summary, we have:

Per year price drop is -41.50$
The cost of an MP3 player in the year 2003 is = $ 499
The cost of an MP3 player in the year 2009 is = $ 249.99
The price drop per year will be –
We need to subtract the base year price from that of the current year price and divide that by the difference between the base year and the current year
The year that serves as the standard against which subsequent values are measured is referred to as the base year.
The term "current year" refers to the fiscal year that has already begun but has not yet completed its cycle.
So,

g is a trigonometric function of the form g(x) = acos(bx+c)+d. Below is the graph of g(x). The function has a maximum point at (3pi/4, "-2)" and a minimum point at (2pi, "-14)." Find a formula for g(x). Give an exact expression.
The formula for the given cosine function is:
g(x) = 6cos(0.8(x - 0.75π)) - 8
Hence the coefficients are:
a = 6, b = 0.8, c = -0.75π, d = -8.
What is the cosine function?The cosine function is defined as follows:
g(x) = acos(bx+c)+d.
The coefficients have these following roles:
a: amplitude.b: The period is of 2pi/B.c: phase shift.d: vertical shift.In this problem, we have that the maximum value is of -2 and the minimum value is of -14(difference of 12), hence the amplitude is given as follows:
2a = 12.
a = 6.
A standard cosine function with amplitude would vary the between -6 and 6, while this one varies between -14 and -2, hence the vertical shift is of d = -8.
The minimum and maximum values form half the period, hence:
[tex]\frac{2\pi}{B} = 2\pi - \frac{3\pi}{4}[/tex]
[tex]\frac{\pi}{B} = \frac{5\pi}{4}[/tex]
B = 4π/5
b = 0.8π.
The minimum value in the standard function is at x = 0, while at this function is at x = 3π/4, hence the phase shift is of 3π/4 = 0.75π units to the right, that is, c = -0.75π.
Hence the formula for the given cosine function is:
g(x) = 6cos(0.8(x - 0.75π)) - 8
The graph of the function is given at the end of the answer.

Using the definition of slope, the points (-2 , 6), (0 , 2), and (1 , 0) are collinear.
Three or more points are said to be collinear if they lie on a single straight line.
To determine whether the given points are collinear, use the definition of slope. The slope, m, determines the steepness of a line. It can be measured by the vertical distance from one point to another divided by the horizontal distance of the same points.
m = (y2 - y1)/(x2 - x1)
Getting the slope of each pair of points:
