What is the wavelength of the photon that will be emitted when a hydrogen electron transitions from the n
Answers
The wavelength of the photon emitted when a hydrogen electron transitions from the n=3 to the n=2 energy level is approximately -7.854 x 10⁻⁸ meters..
The wavelength of the photon emitted when a hydrogen electron transitions from the n=3 to the n=2 energy level can be calculated using the Rydberg formula.
The Rydberg formula is given by:
1/λ = R(1/n₁² - 1/n₂²)
Where λ is the wavelength of the photon, R is the Rydberg constant (approximately 1.097 x 10⁷ m⁻¹), n₁ is the initial energy level, and n₂ is the final energy level.
In this case, the initial energy level (n₁) is 3 and the final energy level (n₂) is 2.
Plugging these values into the formula, we get:
1/λ = R(1/3² - 1/2²)
Simplifying further:
1/λ = R(1/9 - 1/4)
1/λ = R(4/36 - 9/36)
1/λ = R(-5/36)
To find the value of λ, we take the reciprocal of both sides:
λ = -36/5R
Substituting the value of R (1.097 x 10⁷ m⁻¹), we get:
λ ≈ -36/5(1.097 x 10⁷ m⁻¹)
Calculating this value, we find:
λ ≈ -7.854 x 10⁻⁸ m.

The wavelength of the photon emitted when a hydrogen electron transitions from the n1 to the n2 energy level can be calculated using the Rydberg formula: 1/λ = R((1/n1^2) - (1/n2^2)), where λ is the wavelength, R is the Rydberg constant, and n1 and n2 are the initial and final energy levels, respectively.
When a hydrogen electron transitions from one energy level to another, it emits or absorbs a photon of specific energy. This energy can be related to the wavelength of the photon using the equation E = hc/λ, where E is the energy, h is Planck's constant, c is the speed of light, and λ is the wavelength.
In the case of a hydrogen atom, the energy levels are quantized and given by the equation E = -13.6 eV/n^2, where n is the principal quantum number. The initial energy level, n1, is usually a higher value than the final energy level, n2.
Using the Rydberg formula, we can determine the wavelength of the emitted photon. By substituting the values of n1 and n2 into the equation, we can calculate the wavelength.
For example, if the electron transitions from n=3 to n=2, the Rydberg formula becomes 1/λ = R((1/3^2) - (1/2^2)). Solving for λ will give us the wavelength of the emitted photon.
Please note that the Rydberg formula is specifically applicable to hydrogen atoms or hydrogen-like ions.

What do you think is a realistic goal for Atlas to shoot for overall in reduction of outstanding amounts each month (this can be in actual dollars or a percentage of the total amount currently due)
Answers
Ultimately, the specific goal for Atlas will depend on its unique circumstances, financial position, and growth objectives.
Setting a realistic goal for Atlas to reduce outstanding amounts each month depends on various factors, including the company's financial situation, industry norms, and specific objectives. However, a common approach is to aim for a consistent reduction in outstanding amounts over time while considering practical limitations and sustainability.
One possible goal could be to target a percentage reduction in outstanding amounts each month. This could be based on factors such as historical data, industry benchmarks, and the company's financial capabilities. For example, Atlas could set a goal of reducing outstanding amounts by 5% each month.
Alternatively, Atlas could establish a specific dollar amount as a target for reduction. This could be based on the company's financial goals, cash flow projections, and outstanding debt levels. For instance, Atlas could aim to reduce outstanding amounts by $10,000 each month.

Which set of numbers can represent the side lengths, in inches, of an acute triangle?
o 4,5,7
O 5,7,8
O 6,7, 10
O 7.9, 12
Answers
Answer:
5 , 7 , 8 represent the side of acute angled triangle
Set B with sides 5 , 7 , 8 represent the side of acute angled triangle.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that:
Set of numbers.
Now, We use the following result:
When given 3 triangle sides then to determine if the triangle is acute angled , right angled or obtuse angled.
First find Square all 3 sides, then Sum the squares of the 2 shortest sides and then Compare the sum to the square of the last side.
if sum > Square of last side ⇒ it is Acute Triangle
if sum = Square of last side ⇒ it is Right Triangle
if sum < Square of last side ⇒ it is Obtuse Triangle
a). 4 , 5 , 7
4² = 16 , 5² = 25 , 7² = 49
16 + 25 = 41
Hence, 41 < 49
⇒ It is an Obtuse Triangle.
b). 5 , 7 , 8
5² = 25 , 7² = 49 , 8² = 64
25 + 49 = 74
Hence, 74 > 64
⇒ It is an acute Triangle.
c). 6 , 7 , 10
6² = 36 , 7² = 49 , 10² = 100
36 + 49 = 85
Hence, 85 < 100
⇒ It is an Obtuse Triangle.
d). 7 , 9 , 12
7² = 49 , 9² = 81 , 12² = 144
49 + 81 = 130
Hence, 130 < 144
⇒ It is an Obtuse Triangle.
Therefore, Set B with sides 5 , 7 , 8 represent the side of acute angled triangle.

Answers
Answer:
C. 60°
Step-by-step explanation:
The vertical angle formed inside a circle when two chords intersect each other is equal to half the sum of the measures of the intercepted arcs, based on the intersecting chords angle measure theorem.
Thus:
90° = ½(120° + arc TA)
Multiply both sides by 2
2*90 = 120 + arc TA
180 = 120 + arc TA
Subtract 120 from each side
180 - 120 = arc TA
60° = arc TA
Arc TA = 60°

The navigator a lighthouse on some rocks at point R. The bearing from point A to the rocks is 24 degrees, as shown. The ship then sails 4.7 km north to point B. From point B, the bearing to the rocks is 57 degrees, as shown. Find the distance from B to R. R 570 B 4.7 km 24°
Answers
The polar form of the product zw is zw = 45(cos 34° + i sin 34°), and the polar form of the quotient zw is zw = 5(cos 14° + i sin 14°).
What are the polar forms of the products zw and zw?To find the product of two complex numbers in polar form, we multiply their magnitudes and add their arguments.
To find the product zw, we multiply the magnitudes and add the arguments:
z = 15(cos 24° + i sin 24°)
w = 3(cos 10° + i sin 10°)
The magnitude of zw is the product of the magnitudes of z and w:
|zw| = |z| * |w| = 15 * 3 = 45
The argument of zw is the sum of the arguments of z and w:
arg(zw) = arg(z) + arg(w) = 24° + 10° = 34°
Therefore, zw = 45(cos 34° + i sin 34°) in polar form.
To find the quotient zw, we divide the magnitudes and subtract the arguments:
zw = |zw| * (cos arg(zw) + i sin arg(zw))
= 45(cos 34° + i sin 34°)
Hence, zw = 45(cos 34° + i sin 34°) in polar form.
For the second part of the question:
Given:
Ship at point A sailing directly north.
Bearing from A to the rocks (point R) is 24 degrees.
Ship sails 4.7 km north to point B.
Bearing from B to the rocks is 57 degrees.
To find the distance from B to R, we can use the law of sines. Let d be the distance from B to R.
sin(57°) / d = sin(90° - 24°) / 4.7
Simplifying the equation, we have:
sin(57°) / d = cos(24°) / 4.7
Cross-multiplying, we get:
d = 4.7 * (sin(57°) / cos(24°))
Calculating the value, we find that d is approximately 6.31 km.
Therefore, the distance from B to R is approximately 6.31 km.
