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

At the midpoint of the journey, the Sun as well as Tau Ceti explode. at the same instant.
Now, the distance between the Sun and the spacecraft:
L = L(p) √( 1 - (v/c)²)
L = (6 ly) √[1 - (0.8)²] = 3.6 ly
Now, we observe Sun to be flying away from us at a speed of 0.8c whereas the light from the Sun approaches at a speed 1c. Therefore, the gap between the Sun and the blast of the Sun wave is opened at a speed of 1.8c.
Therefore, the time passed ever since the Sun exploded is:

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.

The interference pattern that you you see on the interior surface of the cylinder is (a) bright and dark fringes so closely spaced as to be indistinguishable
What is Young's double slit experiment?Young's double slit experiment is the experiment performed in 1801 by Thomas Young to prove that light is a wave.
Since you are performing Young's double-slit experiment with the slit separation slightly smaller than the wavelength of the light and as a screen, you use a large half-cylinder with its axis along the midline between the slits.
What interference pattern will you see on the interior surface of the cylinder?Now, we know that the interference pattern of a Young's double slit experiment is as a result of diffraction.
What is interference pattern?Interference pattern is the pattern observed due to the vectorial combination of waves
What is diffraction?Diffraction is the property of a wave in which a wave spreads out as it passes through an opening.
Now, we know that diffraction occurs when a wave goes through an aperture or opening smaller than its wavelength.
Now, the smaller the opening compared to the wavelength of the wave, the more the diffraction you would observe bright and dark fringes so closely spaced as to be indistinguishable.
So, the interference pattern that you you see on the interior surface of the cylinder is (a) bright and dark fringes so closely spaced as to be indistinguishable

a small turbo prop commuter airplane accelerates before taking off calculate the acceleration of the planbe
The calculated acceleration is for plane and in 19 s 2.63 m/s2 and 475.25 m respectively.
An object's velocity can alter depending on whether it moves faster or slower or in a different direction. A few instances of acceleration include an apple falling, the moon orbiting the earth, or a car being halted at a set of traffic lights.
We employ the following equation to resolve the first portion of this problem.
Vf = 50 m/s final speed
Initial speed: 0 V
t=time
a=acceleration
a=(Vf-Vo)/t
a= (50-0)/19=2.63m/s^2
The following equation is used for this problem's second component.
X=(Vf^2-Vo^2)/2a
X= (50^2-0^2)/ (2*2.63)
=475.25m

A car moves 92 km due east, then 56 km due west. what is its total displacement?
By using vector, the total displacement is 36 km.
We need to know about vectors to solve this problem. Vector has magnitude and also direction. Displacement is included in vector. It can be written as
s = sx i + sy j + sz k
where s is displacement, sx is displacement on x-axis, sy is displacement on y-axis and sz us displacement on z-axis.
From the question above, we know that
east = positive x
west = negative x
s1 = 92i km
s2 = -56i km
Hence, the total displacement is
s = s1 + s2
s = 92i - 56i
s = 36i
Find the magnitude
|s| = √sx²
|s| = √36²
|s| = 36 km

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. W= Fd is the equation illustrating the relationship.F stands for force in newtons, W for work measured in joules, and d for distance in meters.To learn more about displacement, visit:

"4. Two long, parallel wires each carry the same current I in the same direction (Fig. OQ 30.4) . Is the total magnetic field at the point P midway between the wires (a) zero,(b) directed into the page,(c) directed out of the page,(d) directed to the left, or (e) directed to the right?"
Total magnetic field at the point P midway between the wires is Zero.
The higher wire's contribution to the magnetic field at point P is directed into the page, whereas the lower wire's contribution is directed out of the page. These two oppositely directed contributions to the magnetic field have identical magnitudes and cancel each other out since point P is equally spaced from the two wires and the currents flowing through them are of equal magnitude.
Define magnitude?The term "magnitude" refers to an object's greatest size and direction. Scalar and vector quantities both use magnitude as a common factor. We are aware that scalar quantities are those that have just magnitude by definition. Those quantities with both magnitude and direction are considered vector quantities. It can also be used to describe how far an object has travelled or how much an object weighs in terms of its magnitude.

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
v=0.98×c
v=0.98c
Therefore, the speed of the electron is 0.98c. #SPJ4

Based on the information you have seen, in which sport do the players have a greater change of hitting a home run? Use your understanding of forces to explain.
Then step off and then throw to the base where the infraction occurred. There is no need to tell an umpire what you are appealing the players have a greater change of hitting a home run.
What is home run?In baseball, a home run (abbreviated HR) is scored when the batter is able to safely round the bases and get to home plate in one play without any errors from the opposing team's defense. Typically, a home run is obtained by launching the ball over the outfield fence in between the foul poles (or by striking either foul pole) without allowing it to touch the field. A much less frequent type of home run is one that occurs "within the park," in which the batter makes it safely home while the ball is still in play on the field.
A hit, a run scored, and a run batted in (RBI) are all given to the batter when a home run is hit.
