In a series circuit with two capacitors and a potential difference of 100 V, if the capacitance of C1 is 10 microfarads and the voltage drop across it is 75 V, the capacitance of C2 is approximately 133.33 microfarads.

In a series circuit, the total potential difference across the capacitors is equal to the sum of the individual voltage drops across each capacitor. In this case, we have a potential difference (V) of 100 V and a voltage drop (V1) across C1 of 75 V.

Using the formula for the potential difference across a capacitor, V = Q/C, where Q is the charge and C is the capacitance, we can express the voltage drop across C1 as V1 = Q1/C1.

Given the capacitance of C1 (C1 = 10 microfarads) and the voltage drop across it (V1 = 75 V), we can rearrange the equation to solve for the charge on C1:

Q1 = C1 * V1.

Now, since the total charge across both capacitors in a series circuit is the same, we can express the charge on C2 (Q2) as:

Q2 = Q1 = C1 * V1.

Next, we can calculate the voltage drop across C2 (V2) using the formula: V2 = Q2 / C2.

Substituting the value of Q2 and rearranging the equation, we get:

V2 = (C1 * V1) / C2.

Given that V2 is the remaining potential difference (V - V1) of 25 V, we can set up the equation:25 = (C1 * V1) / C2. Simplifying the equation, we find: C2 = (C1 * V1) / 25.

Substituting the values of C1 = 10 microfarads and V1 = 75 V, we can calculate the capacitance of C2: C2 = (10 * 75) / 25 = 30 microfarads.

Therefore, the capacitance of C2 is approximately 133.33 microfarads.

The thickness of the mica sheet is approximately 0.012 mm, B.

Let the thickness of the mica sheet be t, and let the distance between the slits and the screen be D. The shift in the position of the center of the fringe pattern can be given by:

Δy = λD/d

where λ = wavelength of the light, and d = distance between the two slits.

In the presence of the mica sheet, the light passing through the mica has to travel an extra distance of 2t through the mica, which causes a phase shift of:

δ = (2π/λ) × (n - 1) × t

where n = refractive index of the mica.

For the dark fringes, the phase difference between the two beams is an odd multiple of π, i.e.,

Δφ = δ + πk = (2k + 1)π

where k = an integer.

The shift in the position of the center of the fringe pattern corresponds to 30 dark bands:

Δy = 30 × λD/d

Equating this expression to the optical path length difference:

δ = (2π/λ) × (n - 1) × t = 30 × λD/d

Substituting the given values:

(2π/480 nm) × (1.60 - 1) × t = 30 × 480 nm × D/d

Simplifying:

t = (30 × 480 nm × D/d) / (2π × 0.60)

t = 0.012 mm

Therefore, the thickness of the mica sheet is approximately 0.012 mm, which is (b).

the speed of the fast train is: u = 1.4 x 10^2 m/s

The beat frequency is the difference between the frequencies of the two sound waves coming from the trains. We can use this information to calculate the speed of the fast train.

First, we need to know the frequency of the sound wave emitted by each train. Let's call the frequency of the sound wave from the fast train f1 and the frequency of the sound wave from the slow train f2.

We can use the formula for beat frequency:

beat frequency = |f1 - f2|

Plugging in the given beat frequency of 4.2 Hz, we get:

4.2 Hz = |f1 - f2|

Next, we can use the Doppler effect formula for sound:

f = (v +/- u) / (v +/- vs) * f0

where:
f = observed frequency
v = speed of sound (343 m/s)
u = speed of the observer (unknown)
vs = speed of the source (unknown)
f0 = frequency of the sound wave emitted by the source

For the observer standing near the tracks, we can assume that vs = 0.

So for the sound wave from the fast train, we have:

f1 = (v + u) / v * f0

And for the sound wave from the slow train, we have:

f2 = (v - u) / v * f0

Substituting these into the beat frequency equation and simplifying, we get:

4.2 Hz = u / v * f0

Solving for u, we get:

u = 4.2 Hz * v / f0

Plugging in the given frequency of the sound wave from the fast train (which is the same as f0), we get:

u = 4.2 Hz * 343 m/s / f1

Rounding to two significant figures, the speed of the fast train is:

u = 1.4 x 10^2 m/s

The upthrust on the wooden cube is 1.57 x 10⁴ N.

According to Archimedes' Principle, when an object is immersed in water, it displaces its own weight of water, resulting in an upward force, or upthrust, on the object.

When an object is fully immersed in a fluid, the upthrust on it is equal to the weight of the fluid displaced by the object.

The upthrust on a wooden cube with sides measuring 2m, which is immersed in water as shown in the figure, must be calculated. 6m 2m Rectangular body Water .

​[Figure]The density of water is 1000 kg/m³.

The mass of water displaced by the cube is equal to its volume multiplied by its density.

The volume of the cube can be calculated using the formula:

Volume of cube = Side x Side x Side

Using this formula, we get

Volume of cube = 2 x 2 x 2Volume of cube = 8 m³

Therefore, the mass of water displaced by the cube is

Mass = Density x Volume

Mass = 1000 kg/m³ x 8 m³Mass = 8000 kg

The weight of water displaced by the cube is

Weight = Mass x Gravity

Weight = 8000 kg x 9.81 N/kg

Weight = 78480 N

Therefore, the upthrust on the wooden cube is

Upthrust = Weight of water displaced

Upthrust = 78480 NUpthrust = 1.57 x 10⁴ N.

Since we don't have the voltage or length of the wire given in the question, we cannot determine the electric field.

The current density in a wire is the current per unit area of the wire. To find the current density, we can use the formula:
Current density (J) = Current (I) / Cross-sectional area (A)
First, let's find the cross-sectional area of the wire. The wire has a diameter of 2.1 mm, so the radius is half of that, which is 1.05 mm (or 0.00105 m). The cross-sectional area can be found using the formula for the area of a circle:
A = π * r^2
Substituting the values, we get:
A = 3.14 * (0.00105)^2

= 3.459 x 10^-6 m^2
Now we can find the current density by dividing the current by the cross-sectional area:
J = 20 A / 3.459 x 10^-6 m^2
Calculating this, we get:
J ≈ 5.77 x 10^6 A/m^2
To find the electric field under these conditions, we can use Ohm's law:

Answer: When a car is struck by lightning, the resulting electric field inside the car is zero.

Explanation:

Light bends when it travels from a certain density of matter into a different density of matter. The density of the stuff affects how much it bends. Light bends when it transitions from air to water or from water to air. Light bends when it travels from water to glass or from glass to air. How much light is bent by a particular substance may be determined by its index of refraction. However, Snell's Law and the angle of incidence must be coupled. The angle of refraction increases with increasing angle of incidence. As a result, the water's unique index of refraction bends light entering the medium at an angle of 30°. and that is 1.33.  This means that light in a vacuum travels at 1.33 times faster than light in water. We wouldn't have lenses in the way we do now without refractive index. We would need eyes with pinhole-sized openings in order to see, which would prevent us from seeing clearly or at least in great detail. We wouldn't have had microscopes to view anything in great detail, telescopes to view the moon, planets, or distant things. I could go on, but I think you get the idea: if we didn't have the material characteristic known as refraction, things would be quite different. Well, I guess it's possible that human eyes have evolved to have diffractive lenses, but that's another theory.

________________________

The ability of a substance, whether it is solid, liquid, or gas, to reflect light causes it to move more slowly than it would in a vacuum.

Any substance's refractive index (n) is found by dividing the speed of light in that substance by the speed of light in a vacuum (c) (v).

So

n = c/v

Since a material's refractive index varies depending on the wavelength of light, n = f(wavelength) (n is a function of wavelength). In comparison to longer wavelengths, the index is larger for shorter wavelengths. It's known as dispersion.

When creating lenses or other refractive optical systems, the refractive index and dispersion are both crucial factors. The diverse wavelengths don't come to a common focus, which has a disastrous effect on image quality because index is directly related to how light bends while passing through a lens. We refer to this as chromatic aberration. It's difficult to regulate, but you can achieve it by carefully selecting various glass chemistries and massaging them into position. The glass map showing index as a function of inverse dispersion is seen in the image below. About 20 to 100 is the range of the Abby number, a measure of dispersion; lower numbers indicate more dispersion (larger index difference between red and blue light). Every dot stands for a distinct glass.

Refractive indices range from 1.0003 for air, to over 4.5 for Geranium.

It's essential to terminate coaxial cables with connectors rated for the exact cable type because it ensures optimal performance, signal integrity, and impedance matching.

Terminating a coaxial cable with connectors that are rated for the exact cable type is important because it ensures optimal performance and signal integrity. Coaxial cable is designed to carry high-frequency signals, and the connectors play a crucial role in maintaining the quality of those signals. Different cable types have different electrical characteristics, such as impedance, capacitance, and attenuation, and using the wrong connectors can lead to impedance mismatches, signal loss, interference, and other issues. For example, if you use connectors with a higher impedance rating than the cable, it can cause reflections and reduce the amount of power that reaches the destination. On the other hand, if you use connectors with a lower impedance rating, it can cause signal distortion and reduce the signal-to-noise ratio. Therefore, it is important to choose connectors that match the cable type and meet industry standards to ensure reliable and consistent performance.

By using the blackbody radiation formula, the temperature of the filament inside the bulb is changed by a factor of 10⁰'²⁵.

To tackle this issue, we need to understand black body radiation. A black body object's energy emission is inversely proportional to its area and the temperature to the fourth power. It may be established that

P = A . e . σ . T⁴

where P (power), A (surface area), e (emissivity), ( 5.67 x 10¯⁸ W/m²K⁴), and T (temperature) are all variables.

From the question above, we know that

P1 = 10 watt

P2 = 100 watt

T1 = T1

By using the black body radiation formula, the ratio of temperature is

T1⁴ / T2⁴ = P1 / P2

Hence,

T1⁴ / T2⁴ = P1 / P2

T1⁴ / T2⁴ = 10 / 100

T1⁴ / T2⁴ = 1 / 10

T2⁴ = 10T1⁴
