Answer:

Cylinder A has Plasma

Explanation:

The question is incomplete because the figure is not given in the question. I have attached the figure at the bottom for this question. Consult it for better understanding.

We can discard the options C and D as C shows a the characteristics of a liquid (fixed volume) while D shows the characteristics of a solid (fixed shape and volume)

Plasma is basically a state, which is a lot similar, yet different to the state of gas. Like gases, it doesn't have a fixed shape or volume, but unlike gases, it has only charged particles. A plasma can be considered as a charged gas.

As A shows charged ions, while in B, these ions are in pair and are neutralized, we can say that the charged gas is in A. Therefore, option A has plasma

Adults with good attention spans typically have reaction times of 0.75 seconds or less. 28 m/s is equal to 100 km/h in velocity.

The direction of moving mass or object depends on its velocity. Speed can be thought of as a real number in its simplest form. Velocity is essentially a vector quantity. It is the speed at which distance is changing. The problem is the displacement change rate.

The distance before the car comes to a complete stop increases during the reaction time since the vehicle is still moving at a constant speed.

Adults with good attention spans typically have reaction times of 0.75 seconds or less.

=100 km/1 h

=100000m/3600s

=28 m/s .

Consequently, the car moves 21 meters in 0.75 seconds.

In Rutherford's famous set of experiments, the fact that some alpha particles were deflected at large angles indicated that the atom contains a dense, positively charged nucleus.

Rutherford conducted experiments where he bombarded a thin gold foil with alpha particles. According to the prevailing model at the time, the Thomson model, it was believed that the positive charge in an atom was spread uniformly throughout the atom, much like plum pudding.

However, Rutherford's observations revealed that some alpha particles experienced significant deflections and even bounced back at large angles. This unexpected result could not be explained by the Thomson model.

Rutherford proposed a new atomic model known as the nuclear model, suggesting that the atom consists of a tiny, dense, positively charged nucleus at the center and the majority of the atom is empty space. This explained the deflection of alpha particles, as they were repelled or deflected by the positive charge concentrated in the nucleus.

The deflection of alpha particles at large angles indicated the presence of a compact and positively charged nucleus within the atom, leading to a fundamental revision of the understanding of atomic structure.

In a longitudinal wave, the compressions and rarefactions travel in the same direction.

A longitudinal wave is a type of wave where the direction of vibration is parallel to the direction of energy propagation. This means that the wave is traveling in the same direction that the particles are vibrating.

Longitudinal waves are characterized by compressions and rarefactions. In a compression, the particles of the medium are compressed, or pushed together, while in a rarefaction, the particles of the medium are spread apart.

These compressions and rarefactions travel through the medium, creating a wave pattern. Longitudinal waves can be found in many different types of waves, including sound waves and seismic waves.

In sound waves, the compressions and rarefactions are created by the vibration of the air particles, while in seismic waves, the compressions and rarefactions are created by the movement of the ground.

Therefore, the compressions and rarefactions of a longitudinal wave move in the same direction.

The formula HM=U2Sin2 2g...(1), where U is the initial velocity, and g is the acceleration due to gravity, determines the highest height that a projectile can reach while disregarding air resistance. (28.2m/s).

a) The initial velocity components of a projectile thrown at a speed of vi and an angle of I above the horizontal are vxi = vi cos I and vyi = vi.sin i. When the projectile returns to the level from which it was launched (in this case, the ground), ignoring air resistance, its vertical velocity will be v.y=-vyi.

With this knowledge, the entire flight time can be calculated as follows: t total = v.yf v yi/ay = v yi v yi/g = 2vyi/g or t total = 2vi sini/g.

Given that a projectile's horizontal velocity is constant in the absence of air resistance, its range may be calculated using the following formula:

R=vxi t total =(vi cosθ i)( 2vi sinθ i/g )= vi2/g (2sinθ i cosθ i​ )

= vi2 sin(2θ 1)/g.

Thus, if the projectile is to have a range of R=81.1m when launched at an angle of θ i =45.0 0 , the required initial speed is

vi= \(\sqrt{x} Rg/sin(2θ i )\)= \(\sqrt{x} (81.1m)(9.80m/s 2 )/sin(90.0 0 )\)=28.2m/s

The apex—the highest point on any trajectory—is attained when vy = 0. We can compute y because we know the initial position, initial velocity, and final velocity by using the equation v2y=v20y2g(yy0).

At equilibrium, the forces exerted by the front and back hooves must be equal, but the force exerted by the front hooves will be slightly greater than that of the back hooves.

What is equilibrium?
Chemical equilibrium refers to the situation inside a chemical reaction where both the reactants are present at levels that have no further habit of changing over time, preventing any discernible change in the system's properties. Whenever the forward reaction and the reverse reaction move forward at the same speed, this condition results. The forward as well as backward reactions typically have equal, if not zero, reaction rates. The concentrations of a products and reactants do not change on a net basis as a result. Dynamic equilibrium is the name given to such a situation.

This is due to the fact that the horse's center of gravity is closer to the front hooves, and thus the front hooves must exert a greater force in order to keep the horse balanced.

Plant cell divide by mitosis so as to :

In the process of cell division known as mitosis, the cell's nucleus divides (in a multiple phase), producing two identical daughter cells. To create two identical diploid daughter cells that are genetically identical to the diploid parent cell, mitosis requires chromosome replication. Your cells will all have the same DNA makeup as a result.

Three essential factors: asexual reproduction, replacement of developing and growing cells, and importance of mitosis.

1. Development and growth.

Mitosis is the process by which an embryo grows after a gamete from meiosis has united with another gamete to form an embryo. In plants, animals, and fungi alike, this growth occurs throughout an organism's lifespan. The initial chromosomal set is kept in this fashion.

2. Replacement of cells.

When the original cell is hurt or damaged, this happens. Damaged cells are replaced by brand-new ones that are produced. The healing of a cut or a shattered bone are two examples of this. To maintain continued functionality, new cells replace old ones when they degenerate.

3. Asexual Reproduction.

Yes, the claim is reasonable. In steady-state heat conduction, the temperature distribution in a solid cylindrical rod with constant temperature boundary conditions and insulated side surface will indeed be linear along the axis. This is because heat is conducted through the rod by diffusion and the rate of heat flow is proportional to the temperature gradient. In a cylinder, the temperature gradient is maximum at the boundaries and zero at the center, leading to a linear temperature distribution.

Temperature, or temperature is a measure of the level or degree of heat on an object. Temperature shows the level of the amount of heat energy that is in the object. Discussion: The higher the temperature of an object, the hotter it is, and the more heat energy in that object.

The height of the parabolic arch bridge at distances of 10, 30, and 50 feet from the center is 19.7917, 23.9583, and 25.0000 feet, respectively.

To answer this question, we must first choose a suitable rectangular coordinate system. The origin, (0,0), of the coordinate system should be located at the center of the bridge, which is located at x = 0. The y-axis should be perpendicular to the bridge and the x-axis should be parallel to the bridge.

To find the height of the arch at distances of 10, 30, and 50 feet from the center, we can use the formula for a parabolic arch, y = a(x - h)² + k. We can calculate the coefficients a and k by using the given maximum height and span of the bridge. We can set y = 25 and x = 120, and then solve for a and k.

\(a = \dfrac{-25}{1202}\)

a = -0.04167,

k = 25

Now, we can substitute the distances of 10, 30, and 50 feet into the formula, and calculate the corresponding height values.

At x = 10 feet: y = -0.04167(10 - 0)2 + 25 = 19.7917 feet

At x = 30 feet: y = -0.04167(30 - 0)2 + 25 = 23.9583 feet

At x = 50 feet: y = -0.04167(50 - 0)2 + 25 = 25.0000 feet

Therefore, the height of the parabolic arch bridge at distances of 10, 30, and 50 feet from the center is 19.79, 23.95, and 25.00 feet, respectively.

The quantity needs to be larger than the frequency of the external voltage.

High-frequency filtering is a technique used to remove unwanted noise from a signal. In order for the amplitude of the voltage drop across the capacitor to be less than that of the external voltage, the quantity must be large enough to filter out frequencies higher than that of the external voltage. The cutoff frequency of the filter is determined by the value of the capacitor and the resistor in the circuit.

As the value of the capacitor increases, the cutoff frequency decreases, allowing lower frequencies to pass through the filter. Therefore, in order to achieve the desired result, the value of the capacitor should be chosen such that it is larger than the frequency of the external voltage, but not too large to affect the desired frequency range of the signal.

The resistance of the wire is 0.11 Ω.

To calculate the resistance of the wire, we need to use Ohm's law, which states that resistance (R) is equal to the product of the material's resistivity (ρ), its length (l), and the inverse of its cross-sectional area (A). In formulaic terms, this is represented as:

R = ρ * l / A

Given the values provided in the question, we can plug them into the formula to obtain the resistance of the wire:

R = (1.76 × 10^-8) * 2 / ((π/4) * (0.002)^2)

Simplifying this expression, we get:

R = 0.11 Ω

The resistivity of a material is a measure of how much it opposes the flow of electric current through it. It is an intrinsic property of the material and depends on its composition and structure. The higher the resistivity, the more difficult it is for current to flow through the material. In contrast, materials with lower resistivity offer less opposition to current flow.

In this case, we were given the resistivity of the wire's material and used it, along with its length and cross-sectional area, to calculate its resistance. The resistance of a wire determines how much current will flow through it for a given voltage. Therefore, by knowing the resistance, we can predict the behavior of the wire in an electrical circuit.
