The answer to the given question is 820 Kelvin. Gauss' Law demonstrates how electric fields, E, can be produced by static electricity, q. Gauss' Law, which bears the name of German physicist Carl Friedrich Gauss, is the third of Maxwell's four equations. According to Gauss' Law, an electric charge, qv, or static electricity, produces an electric field, E. (voltage).
This question is an application of Gauss Law, which states that the pressure P and temperature T of an ideal gas are directly proportional to one another. In other words, adiabatic increase in pressure will result in the same rise in temperature. Mathematically,
it can be written as:
P1/ T1 = P2/ T2
Therefore, Temperature T2 = 275 kPa * 298K / 100 kPa = 820 K. Thus, the minimum compressor exit temperature possible is 820 Kelvin.

Light with a frequency of 7. 30 x 1014 hz lies in the violet region of the visible spectrum. What is the wavelength of this frequency of light? please answer in nm and round to the nearest whole number.
Light with a frequency of 7.30 x 10¹⁴ that lies in the violet region of the visible spectrum has a wavelength of 412nm.
What is wavelength?The wavelength of light can be defined as the distance between two successive crests, or troughs of a wave of light, usually denoted by the Greek letter, lambda (λ).
Wavelength is directly proportional to frequency. This means that the shorter the wavelength, the higher the frequency. To find the wavelength of any electromagnetic wave if we are given the frequency, we use the following formular:
λ = [tex]\frac{v}{f}[/tex]
Where;
λ represents the wavelengthv is the velocity of lightf is the frequency of the waveThe velocity or speed of light is the same for all electromagnetic waves which is 3 x 10⁸m/s. We are already given the frequency in the question as 7.30 x 10¹⁴hz. Putting these values into the formular:
λ = 3 x 10⁸/7.30 x 10¹⁴
λ = 4.12 x 10⁻⁷m
However, to convert the wavelength from meter to nanometer, we would have to multiply the answer by 10⁹. Therefore;
λ = 4.12 x 10⁻⁷m x 10⁹ = 412nm

The big o notation of the worst-case scenario of pushing back an
element into a queue implemented using a list is Array or a Linked list.
What is an array?
A queue could be implemented as an array or a linked list with very different insertion, removal, and indexing characteristics.In computer science, an array is a data structure consisting of a collection of elements, each identified by at least one array index or key. An array is stored such that the position of each element can be computed from its index tuple by a mathematical formulaThe array in C has a fixed size, which means that once the size is specified, it cannot be changed; you cannot shrink or expand it. The rationale behind this was that, when expanding, we cannot always be certain that we will receive the subsequent memory location for free (it is not always possible). The array is memory statically allocated when it is declared, making it impossible to shrink because only the compiler has the power to do so.The first element of the array is indexed by the subscript 0, for zero-based indexing; by the subscript 1, for one-based indexing; and by the subscript n, for N-based indexing. An array's base index can be chosen at will. Negative index values are typically permitted in programming languages that support n-based indexing, and other scalar data types, such as enumerations or characters, may also be used as array indexes.

b.) 0, 18 m/s
c.) 21.2 m/s, 0
d.) 23 m, 39 m
e.) 2.2 s
Motion Under GravityMotion of any object under gravity is the vertical motion of the object under the influence of acceleration due to gravity.
From the question, the following parameters are given.
Height h = 23 mInitial velocity u = 18 m/sa.) The vertical acceleration will be equal to acceleration due to gravity which is equal to 9.8 m/s². While the horizontal acceleration will be equal to zero.
b.) The vertical initial velocity is zero. Vertically, it will be assumed that the stone is dropped. While the given initial velocity is the horizontal initial velocity which is 18 m/s
c.) The vertical final velocity V can be calculated by using the formula
V² = U² + 2gH
V² = 0 + 2 × 9.8 × 23
V² = 450.8
V = √450.8
V = 21.23 m/s
Motion under gravity only act on the vertical component of the velocity. so, horizontal final velocity is equal to zero.
d.) Vertical distance = 23 m
While the horizontal distance = Range = ut
e.) Both the vertical and horizontal time will be the same. We can calculate the time by using the formula
h = ut + 1/2gt²
Vertically, u = 0
23 = 0 + 1/2 × 9.8 × t²
23 = 4.9t²
t² = 23/4.9
t² = 4.694
t = √4.69
t = 2.166 s

We need to know about transition energy to solve this problem. Electrons in a hydrogen atom can move to another level of energy. It is also called a transition. In this process, electrons will absorb or release their energy to move. The transition energy can be determined as
ΔE = E2 - E1
where ΔE is transition energy, E2 is the final state of energy and E1 is the initial state of energy.
The state energy of a hydrogen atom can be calculated by
E = -(13.6) / n² eV
E = h.c / λ
where n is the number of energy states, h is Planck constant (4.136 x 10¯¹⁵ eV/Hz), c is speed of light (3 x 10⁸ m/s) and λ is wavelength.
From the question above, we know that
n1 = 5
n2 = 2
By substituting the following parameter, we get
ΔE = E2 - E1
ΔE = -(13.6) / n2² - (-(13.6) / n1²)
ΔE = -(13.6) / 2² - (-(13.6) / 5²)

The final magnification will be 100X.
The light compound microscope contains two lenses to assist viewing of small objects. The two lenses are ocular lens and objective lens. Ocular lens is in the eyepiece and magnifies the image. Objective lens is near the sample and magnifies the object. Ocular lens is always 10X. Now, if we use objective lens of 10X, the magnification will be calculated by multiplication. So, the final magnification of the microscope will be 100X.
Compound microscope is commonly used to view the samples in magnification ranging from 40X to 1000X. There are variety of microscopes that provide detailed and highly magnified images, for instance, fluorescence microscope, digital microscope, electron microscope etc.

In the competitive forces model, the central element that the other four elements contribute directly to strength is:___________
In the competitive forces model, the central element that the other four elements contribute directly to strength is rivalry among established firms in the industry.
The Competitive Forces Model is an essential technique in strategic analysis for analyzing an industry's competitiveness. The concept is most widely known as Porter's Five Forces Model. It consists of the following five forces: rivalry intensity, threat of possible new entrants, buyer negotiating strength, supplier bargaining power, and threat of alternative products and/or services. Among all the five forces, rivalry among established firms contributes to strength.

What is the magnitude of an electric field that balances the weight of a plastic sphere of mass 7.4 g that has been charged to -3.0 nc?
It is a physical field occupied by a charged particle on another particle in its surrounding .The magnitude of electric field will be -0.0241 MN/C.
What is electric field?
A physical field called an electric field surrounds electrically charged particles and attracts or repels all other charged particles nearby. It can also refer to the physical field surrounding a system of charged particles. Electric charges and time-varying electric currents are the building blocks of electric fields. The electromagnetic field, one of the four fundamental interactions (also known as forces) of nature, manifests itself in both electric and magnetic fields.
The electric force in an electric field is given by the equation,
[tex]E = \frac{F}{Q}[/tex]
Since electric field is balanced by the weight of the plastic sphere, the electric force is equal to weight of the sphere.
[tex]F = mg[/tex]
So the equation becomes
[tex]E = \frac{mg}{Q}[/tex]
Putting the value from the question,
m = 0.0074 kg
Q = (-3.0) Nc
g (gravitational acceleration) = 9.8 m/s^2
So, we get
[tex]E = \frac{(9.8)(0.0074)}{(-3.0)}[/tex]
[tex]E = -0.0241 MN/C[/tex]
Hence, the electric field is -0.0241 MN/C.
