The primary distinction between a system's ground state and excited state is that a system's ground state is any state in which its electrons are at their lowest potential energy levels, whereas an excited state is any state in which they are at an energy higher than the system's ground state.
What do you mean by the excited state and the ground state of the electron?
Any quantum state of a system that has higher energy than the ground state is considered to be in an excited state in quantum mechanics. An increase in energy level over a predetermined starting point, typically the ground state, but occasionally an already excited state, is referred to as excitation.
A ground-state atom is one in which moving one or more electrons to different orbitals will not reduce the overall energy of the electrons in the atom. In other words, all of the electrons in a ground-state atom are at their lowest conceivable energy levels.

What is the equivalent resistance of a circuit that contains four 75.0 Ω
resistors connected in series to a 100.0 V battery?
Ο Α. 300.0 Ω
Ο Β. 750.0 Ω
Ο C. 1.33 Ω
Ο D. 175.0 Ω
Answer:
Ο Α. 300.0 Ω
Explanation:
The equivalent resistance of a circuit that contains four 75.0 Ω in series combination 300Ω
What is a parallel and series combination of resistance?When two or more resistors are connected between two same points, they are said to be connected in parallel combination(as shown in fig). The equivalent resistance is the reciprocal and the sum of reciprocals of all resistance connected in parallel combination.
1/Rs = 1/R₁ + 1/R₂ + 1/R₃...........+ 1/R(n).
where Rs is the equivalent or total resistance of the circuit.
In parallel combination, same potential difference exists across each resistor. But current through each resistance is different.
When two or more resistors are connected one after other, they are said to be connected in series as shown in figure. in this combination voltage difference across each resistance is different which is given by ohms law. current flowing through each resistance is same.
equivalent resistance for series combination is given by,
R(s) = R₁ + R₂ + R₃...........+R(n).
Given,
R₁ + R₂ = R₃ = R₄ = 75Ω
For series combination,
R(s) = R₁ + R₂ + R₃+R₄
R(s) = 75+75+75+75
R(s) = 300 Ω

A grating with 250 grooves mm is used with an incandescent light source. Assume the visible spectrum to range in wavelength from 400nm to 700nm . In how many orders can one see (a) the entire visible speed
The number of orders that one can see the entire visible speed is 5 orders.
How to calculate the orders?From the information given, it should be noted that the grating with 250 grooves mm is used and the visible spectrum range in wavelength from 400nm to 700nm. Therefore, the grating spacing will be:
d = (1.00 × 10^-4) / 250
d = 4000nm
Therefore, the number of times that are needed to complete the order will be the same as the number of orders which the long wavelength time will be visible. This will be:
= (4000 × sin 90°)/700
= 5.71
Therefore, the maximum orders will be 5.

Simplify this hypothesis about the Michelson-Morley experiment.
"If the speed of light were constant with respect to the proposed ether through which Earth was moving, then that motion could be detected by comparing the speed of light in the direction of Earth's motion.”
The Michelson-Morley test set out to test whether or not or not the ether becomes an absolute reference body by measuring the velocity of light with admire to the shifting Earth. It became hypothesized that the rate of light ought to alternate with a change within the Earth's velocity across the solar.
The outcomes of the Michelson-Morley experiment found no interference styles which means that the velocity of light is equal in a vacuum. This brought about the realization that mild does now not require any medium to travel. The results of the Michelson-Morley experiment supported Einstein's principle of unique relativity.
It turned into hypothesized that the rate of mild ought to trade with a change in the Earth's pace around the sun. however, no such exchange in velocity of light turned into observed and this became called the null result.

Review. (b) Is this statement true for all angular displacements, for all displacements less than 180° , or only for small angular displacements? Explain.
Small angle approximation is used. Thus, the magnetic dipole displaced from the equilibrium acts as a torsional pendulum only for a small angle.
What is angular displacement?The angle (measured in radians, degrees, or revolutions) through which a point spins around a particular axis or center is known as the angular displacement of a body. Because a body rotates about its axis, its motion cannot simply be analyzed as a particle because it constantly changes its speed and acceleration (t). It is less complicated to think of a body as rigid while dealing with its rotation. When all of the particle separations remain constant during a body's motion—for instance, when its mass is not flying off—the body is said to be rigid. Realistically, everything is susceptible to deformation, but the effects are little and insignificant.

Fossil fuels, hydroelectric power, and wind power ultimately get their energy from _______.
Answer: I would say that the answer to your question is "Nature"
Explanation: Everything that you've listed is related to nature.
if a force f⃗ acts on an object as that object moves through a displacement s⃗ , the work done by that force equals the scalar product of f⃗ and s⃗ : w
If a force f acts on an object as that object moves through a displacement s , the work done by that force equals the scalar product of f and s : w . This is because when the object moves, the force applied to it changes in magnitude and direction.
Therefore, multiplying this change in Force by the distance traveled.
What connection exists between an object's work and its displacement?The distance and direction that an object is moved are known as displacement. While force and displacement are indirectly proportional, work and force are directly proportional.

The rest energy of an electron is 0.511MeV. The rest energy of a proton is 938MeV. Assume both particles have kinetic energies of 2.00MeV. Find the speed of (a) the electron
The speed of the electron is 0.98c, given that the rest energy of an electron is 0.511MeV and the rest energy of a proton is 938MeV, with both particles having kinetic energies of 2.00MeV.
A particle's total energy and the rest energy follow the laws of physics and the theory of relativity. The energy of any particle is equal to mass times the speed of the light-squared relatively.
Where; E=γ.〖mc〗^2
γ is the ratio of total energy to rest energy of the particle.
m_0 is known as the rest mass of the particle.
Rest energy can be written as: E_0=〖m_0 c〗^2
γ=K/E_0 +1 (1)
γ=1/(√1-v^2/c^2 ) (2)
Putting the values of the electron energy into equation (1):
γ=2.00MeV/0.511MeV+1
γ= 3.91 + 1
γ=4.91
From equation (2),
γ=1/(√1-v^2/c^2 )
Squaring both sides of the equation,
γ^2=1/(1-v^2/c^2 )
1/γ^2 =1-v^2/c^2
v^2/c^2 =1-1/γ^2
v/c=√1-1/γ^2
Making v subject of the formula,
v=√1-1/γ^2 ×c (3)
Inserting the values in the equation,
v=√1-1/〖4.91〗^2 ×c
v=√1-1/24.11×c
v=√0.959×c

Mixture has a final temperature of 3.22 ⁰C
What is specific heat capacity ?
Scientifically, specific heat capacity is the quantity of heat (J) absorbed by a material when its temperature increases 1 K (or 1 °C) per unit mass, expressed as J/(kg K) or J/(kg °C).
Q = mCΔT
Ft is the final temperature. It is, however, important to note that ice absorbs heat during the melting and cooling processes, and as such, it does not lose heat to or from the surrounding environment; hence, it conserves energy.
75g of heat rejected by ice = 825g of heat absorbed by water
m(ice)[C(ice) [LH(ice) + C(water)(ΔT)] = C(water) m(water) (ΔT)
So, 75x [ 333.5 + 4.187(Ft - 0)]= 285 x 4.187 x (25 - Ft)
333.5 + 4.187Ft = 3.8 x 4.187 (25-Ft)
333.5 + 4.187Ft = 397.765 -15.9106Ft

Find the vector using parallelogram law [and Pythagoras theorem (h² = a² + o²) h being the hypothenuse, a being the adjacent side and o being the opposite side]
The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, a2 + b2, are equal to the squares on the legs.
What is Pythagorean Theorem called?The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a fundamental relationship between a right triangle's three sides in Euclidean geometry. According to this rule, the areas of the squares on the other two sides add up to the area of the square whose side is the hypotenuse, or the side across from the right angle. The Pythagorean equation, which is typically used to express this theorem, can be expressed as an equation linking the lengths of the legs (a, b), and the hypotenuse (c):
There are several ways to generalize the theorem, including to higher-dimensional spaces, non-Euclidean spaces, objects other than right triangles, and even things that are not triangles at all but n-dimensional solids. The Pythagorean theorem has garnered interest outside of mathematics as a representation of mathematical mystique, power, or obscurity; there are numerous references to it in popular works of fiction, dramas, musicals, songs, stamps, and cartoons.

A straight wire carrying a 3.00-A current is placed in a uniform magnetic field of magnitude 0.280 T directed perpendicular to the wire. (a) Find the magnitude of the magnetic force on a section of the wire having a length of 14.0cm.
The magnitude of the magnetic force on a section of the wire having a length of 14.0cm is 0.1176 N.
What is a magnetic field?The magnetic field is defined as the field the magnetic materials generate or when an electric charge moves in a field region that generates the magnetic field.
It is given that:
A straight wire carrying a 3.00-A current is placed in a uniform magnetic field of magnitude 0.280 T directed perpendicular to the wire.
As we know,
F = i L B sin θ
i = 3 A
L = 14 cm = 0.14 meters
B = 0.280 T
θ = 90 degrees
F = 3(0.14)(0.280)sin 90
F = 0.1176 N
Thus, the magnitude of the magnetic force on a section of the wire having a length of 14.0cm is 0.1176 N.

part a theory please study wave concept and answer the following questions. 1. what is wave? what is the difference between wave motion and particle in motion? what are the characters of mechanical wave?
At various locations in space and time, a wave's intensity varies.
What is the difference between wave and particle?At various locations in space and time, a wave's intensity varies. A particle is typically thought of as something that exists solely at one location in space. Subatomic "particles" travel like waves and interact like particles according to quantum physics. Because they have varying intensities at various points in space and time, they travel in waves. Because they are made up of a single energy unit that can only be absorbed in a single location, they interact like particles.
What are the characteristics of the mechanical wave?
1. There are only two basic methods for moving energy: the flow of waves and the stream of particles. A wave is a type of physical phenomenon that moves energy but does not matter.
2. Generally speaking, a wave is a continuously moving disturbance of a medium, and that medium can either be a field (such as an electric or gravitational one) or a substance (a solid, a fluid).
