The correct answer to Brewster’s angle is 48.8 degrees.

What is Brewsters's law?

The Brewster's angle is the angle of incidence at which polarised light travels perfectly through a clear dielectric surface without being refracted. The light that is reflected from the surface when unpolarized light is incident at this angle is therefore perfectly polarised.

This equation's name is Brewster's law, and the angle it specifies is Brewster's angle. For a glass medium in air, Brewster's angle for visible light is around 56° (n2 = 1.5), while it is roughly 53° for an air-water interface (n2 = 1.33)

Brewster's Angle is defined as the inverse tan of n 2 over n 1. The inverse tan of 1.52 divided by 1.33 is thus 48.8 degrees.

There is about 10 times as much dark matter as visible matter in clusters of galaxies.

Dark matter is a form of matter that does not interact with light or other forms of electromagnetic radiation, making it invisible to telescopes and other instruments that detect light. Its presence can be inferred from its gravitational effects on visible matter, such as stars and gas, in galaxies and clusters of galaxies.

Studies of galaxy clusters have found that the amount of dark matter in these clusters is much greater than the amount of visible matter, by a factor of about 10 to 1. This means that the majority of the matter in galaxy clusters is actually dark matter, and its gravitational effects play a crucial role in shaping the structure and evolution of these cosmic structures.

Explanation:

The electrostatic potential of the conductor is constant throughout the volume.

The electrostatic potential of the conductor is (d) constant throughout the volume. In a conductor in electrostatic equilibrium, the electric potential is constant inside the conductor, regardless of its shape or charge distribution. This means the potential is the same at all points inside the conductor, including the center and the surface.

The electric field inside a conductor in electrostatic equilibrium is zero. The charges inside the conductor redistribute themselves in such a way that the electric field cancels out within the conductor. Therefore, the electric field in the conductor is zero.

When a ribbon is placed on a loop of a spring and it vibrates without propagating with the wave, it suggests that the ribbon is not effectively coupled with the spring's oscillations.

In order for a wave to propagate through a medium, there needs to be a transfer of energy and motion from one particle to another. In the case of a spring, the wave propagates through the sequential compression and expansion of the individual coils.

However, if the ribbon is not tightly attached or securely coupled to the spring, it won't efficiently transfer the motion and energy of the oscillations. Instead, the ribbon will exhibit its own independent vibrations, but it won't propagate along the spring as a wave.

The lack of effective coupling could be due to various factors, such as insufficient contact or tension between the ribbon and the spring, or the ribbon being too lightweight to transmit the wave effectively. It is crucial for the ribbon to have a solid connection with the spring in order to experience the wave-like motion and propagate with it.

Answer:

\(h=3.18\times 10^{-9}\ m\)

Explanation:

Given that,

The volume of a drop, \(V=10^{-10}\ m^3\)

The radius of the circular film, \(r=10^{-1}\ m\)

We need to find the thickness of the film.

We know that,

Volume, \(V=\pi r^2 h\)

So,

\(h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{10^{-10}}{\pi \times (10^{-1})^2}\\\\h=3.18\times 10^{-9}\ m\)

So, the thickness of the file is equal to\(3.18\times 10^{-9}\ m\).

The time constant for the charging process in this circuit is 8 microseconds.

The time constant for the charging process in this circuit, we need to determine the equivalent resistance and capacitance of the circuit.

First, we can simplify the circuit by combining the two 6 Ω resistors in parallel, which gives an equivalent resistance of:

1/R = 1/6 Ω + 1/6 Ω

R = 3 Ω

Next, we can combine the two capacitors in series, which gives an equivalent capacitance of:

C = C1 * C2 / (C1 + C2)

C = 2 μF * 4 μF / (2 μF + 4 μF)

C = 8/3 μF

Now we can calculate the time constant, which is given by the product of the resistance and capacitance:

τ = R * C

τ = 3 Ω * 8/3 μF

τ = 8 μs

Therefore, the time constant for the charging process in this circuit is 8 microseconds.

The given system consists of two 8.0-cm-diameter circular plates separated by 0.95 cm, which are filled with milk. The capacitance of the system can be calculated as follows:Explanation:Capacitance is defined as the charge stored per unit potential difference,using the formula C = Q/V, where C is capacitance, Q is charge, and V is potential difference.

In this case, the capacitance of the system can be calculated using the formula for the capacitance of parallel plate capacitors:

\(C = εA/d\),

where C is capacitance, ε is the permittivity of free space, A is the area of each plate, and d is the distance between the plates.The area of each plate can be calculated using the formula for the area of a circle:

\(A = πr²\),

where r is the radius of the circle.Substituting the given values into the formula, we get:

\(C = εA/dC = (8.85 × 10⁻¹² F/m) × [(π × (8.0/2 × 10⁻² m)²)/0.95 × 10⁻² m]C = 6.21 × 10⁻¹⁰ F\)

Thus, the capacitance of the system is \(6.21 × 10⁻¹⁰ F\).

The amount of charge on each plate when they are fully charged can be calculated using the formula Q = CV, where Q is charge, C is capacitance, and V is potential difference.Substituting the given values into the formula, we get:

\(Q = CVQ = (6.21 × 10⁻¹⁰ F) × (30,000 V)Q = 1.86 × 10⁻⁵ C\)

Thus, the amount of charge on each plate when they are fully charged is \(1.86 × 10⁻⁵ C\).

214.51°C temperature is a certain reaction at equilibrium if ∆h = 86.5 kj/mol and ∆s = 170.2 j/mol

To determine the temperature at which a certain reaction is at equilibrium, we need to use the equation ∆G = ∆H - T∆S, where ∆G is the change in Gibbs free energy, ∆H is the change in enthalpy, ∆S is the change in entropy, and T is the temperature. By rearranging the equation and substituting the given values for ∆H and ∆S, we can solve for the temperature in degrees Celsius.

The equation ∆G = ∆H - T∆S represents the relationship between the change in Gibbs free energy (∆G), the change in enthalpy (∆H), the change in entropy (∆S), and the temperature (T). At equilibrium, ∆G is zero, so we can set ∆G = 0 in the equation.

0 = ∆H - T∆S

Rearranging the equation, we get:

T = ∆H / ∆S

Substituting the given values, ∆H = 86.5 kJ/mol and ∆S = 170.2 J/mol·K, into the equation, we can calculate the temperature (T) in degrees Celsius. It's important to note that we need to convert the units to match before performing the calculation.

\(T=\frac{86.5 kJ/mol}{170.2 J/mol K}\)

T= 214.51°C

Finally, we can compute the temperature in degrees Celsius using the obtained values for ∆H and ∆S.

The interlayer spacing of the graphite (002) peak is 3.348 Å and the interlayer spacing of the graphite (110) peak is 2.131 Å using CoKα radiation.

The Bragg's Law is used to calculate the interlayer spacing of the graphite (002) and (110) peaks using CoKα radiation.

Bragg's law states that for a given crystal lattice and an incident X-ray of wavelength λ, the following equation holds:

nλ = 2d sinθ,

where

n is an integer,

θ is the angle between the incident X-ray and the crystal plane,

and d is the spacing of the crystal planes.

1. Calculation of the interlayer spacing of the graphite (002) peak using CoKα radiation:

For the (002) peak of graphite, θ is the angle of diffraction between the incident CoKα X-ray and the plane of the (002) reflection.

We have the following information:

λ = 1.789 Å,θ = 26.4°

From Bragg's Law:

nλ = 2d sinθ2d sinθ = nλd = nλ/2sinθ

When n = 1,

we get:

d = λ/2sinθd = 1.789/2sin(26.4°)d = 3.348 Å2. Calculation of the interlayer spacing of the graphite (110) peak using CoKα radiation:

For the (110) peak of graphite, θ is the angle of diffraction between the incident CoKα X-ray and the plane of the (110) reflection.

λ = 1.789 Å,θ = 42.8°

From Bragg's Law:

nλ = 2d sinθ2d sinθ = nλd = nλ/2sinθ

When n = 1,

we get:

d = λ/2sinθd = 1.789/2sin(42.8°)d = 2.131 Å

The regular satellites of the giant planets formed via the process of accretion from a circumplanetary disk.

The giant planets in our solar system, such as Jupiter, Saturn, Uranus, and Neptune, are surrounded by a system of moons, which are divided into two main categories: regular and irregular. The regular satellites are large, spherical, and have nearly circular orbits around their host planets. They are believed to have formed from a circumplanetary disk of gas and dust that surrounded the planet during its formation. The gravitational forces of the planet caused the material in the disk to accrete into small bodies, which eventually coalesced into the regular satellites we see today.
