As per the details given, the electric flux through the area when the electric field is perpendicular to the surface is 1.50 × \(10^6 Nm^2/C\). The electric flux through the area when the electric field is parallel to the surface is zero (0 N⋅\(m^2\)/C).

(a) The electric flux through the area may be determined when the electric field is perpendicular to the surface using the formula:

Φ = E * A * cos(θ)

Φ = (6.00 × \(10^5\) N/C) * (2.50 \(m^2\)) * cos(0°)

Φ = 1.50 × \(10^6 Nm^2/C\)

The electric flux through the area when the electric field is perpendicular to the surface is 1.50 ×  \(10^6 Nm^2/C\).

(b) The electric flux across the region is zero when the electric field is parallel to the surface.

This is due to the fact that the electric field lines are parallel to the surface, and no component of the electric field perpendicular to the surface contributes to the flux.

Thus, when the electric field is parallel to the surface, the electric flux across the region is zero  (0 N⋅\(m^2\)/C).

The peak current (I) at this frequency is approximately 1.04 A and the phase angle (∅) is approximately -63.69 degrees.

Part A:

First, let's calculate the reactance values:

The inductive reactance (XL) can be calculated using the formula:

XL = 2πfL

Substituting the given values:

XL = 2π * 60 * 0.10 = 37.68 Ω

The capacitive reactance (XC) can be calculated using the formula:

XC = 1 / (2πfC)

Substituting the given values:

XC = 1 / (2π * 60 * 20 * 10^(-6)) = 132.68 Ω

Next, let's calculate the impedance (Z):

Z = √(R^2 + (XL - XC)^2)

Substituting the given values:

Z = √(65^2 + (37.68 - 132.68)^2) = √(4225 + (-95)^2) = √(4225 + 9025) = √13250 ≈ 115.24 Ω

Now, we can calculate the peak current (I):

I = V / Z

Substituting the given voltage value:

I = 120 / 115.24 ≈ 1.04 A

Therefore, the peak current (I) at this frequency is approximately 1.04 A.

Part B:

To find the phase angle (∅), we can use the formula:

∅ = tan^(-1)((XL - XC) / R)

Substituting the calculated values:

∅ = tan^(-1)((37.68 - 132.68) / 65) ≈ -63.69°

Therefore, the phase angle (∅) is approximately -63.69 degrees.

If the width of the slit is reduced, the width of the central bright fringe will increase. If the distance between the slit and the screen is reduced, the fringe-width will increase.

The width of the central bright fringe in a single-slit diffraction pattern is inversely proportional to the width of the slit. So, if the width of the slit is reduced, the width of the central bright fringe will increase.

The fringe-width is also inversely proportional to the distance between the slit and the screen. So, if the distance between the slit and the screen is reduced, the fringe-width will increase.

To see this, consider the equation for the width of the central bright fringe in a single-slit diffraction pattern:

w = λd / a

where:

w = width of the central bright fringe

Kepler's third law is used to determine the relationship between the orbital period of a planet and the radius of the planet.

The distance of the earth from the sun is \(1.50 \times 10^{11}\;\rm m\).

Kepler's Third Law states that the square of the orbital period of a planet is directly proportional to the cube of the radius of their orbits. It means that the period for a planet to orbit the Sun increases rapidly with the radius of its orbit.

\(T^2 \propto R^3\)

Given that Mars’s orbital period T is 687 days, and Mars’s distance from the Sun R is 2.279 × 10^11 m.

By using Kepler's third law, this can be written as,

\(T^2 \propto R^3\)

\(T^2 = kR^3\)

Substituting the values, we get the value of constant k for mars.

\(687^2 = k\times (2.279 \times 10^{11})^3\)

\(k = 3.92 \times 10^{-29}\)

The value of constant k is the same for Earth as well, also we know that the orbital period for Earth is 365 days. So the R is calculated as given below.

\(365^3 = 3.92\times 10^{-29} R^3\)

\(R^3 = 3.39 \times 10^{33}\)

\(R= 1.50 \times 10^{11}\;\rm m\)

Hence we can conclude that the distance of the earth from the sun is \(1.50 \times 10^{11}\;\rm m\).

In a mixed-tide system, the water levels exhibit two high tides and two low tides within a tidal cycle. The ranking of the water levels according to height is as follows:

Higher high water: This is the highest water level observed during the tidal cycle. It occurs when the gravitational forces of the Moon and the Sun align to produce a stronger tidal bulge. It typically happens around the time of a new moon or a full moon.

Lower high water: This is the second-highest water level observed during the tidal cycle. It occurs when the gravitational forces of the Moon and the Sun are not aligned, resulting in a weaker tidal bulge. It typically happens around the time of the first quarter and third quarter moon phases.

Higher low water: This is the higher of the two low water levels observed during the tidal cycle. It occurs when the gravitational forces of the Moon and the Sun produce a weaker tidal trough. It typically happens between the two high tides.

Define Phase change

Phase change is the physical process that transforms a material from one state to another. The shift often happens when heat is applied or removed at a specific temperature, also referred to as the substance's melting or boiling point.

Water that has lost all of its thermal energy freezes, converting from a liquid to a solid. This is something we encounter frequently in daily life. When the water gets cold enough, puddles, ponds, lakes, and even portions of oceans begin to ice. Surface water on Earth freezes at low temperatures and turns into solid ice.

To find the average velocity on a velocity-time graph, you need to calculate the slope of the line connecting two points on the graph. The average velocity represents the change in velocity divided by the change in time between those two points.

To calculate the average velocity, you can use the formula:

Average velocity = (change in velocity) / (change in time)

You can determine the change in velocity by finding the difference between the final velocity and the initial velocity. The change in time is the difference in the time coordinates of the two points.

Select two points on the velocity-time graph, typically denoted by (t₁, v₁) and (t₂, v₂), where t represents time and v represents velocity. Then, substitute the values into the formula mentioned above to calculate the average velocity.

It's important to note that the average velocity provides information about the overall change in velocity over a specific time interval, rather than instantaneous velocity at a particular moment.

The electric flux through the pyramid is approximately 37.29 N·m²/C.

To calculate the electric flux through the pyramid, we need to determine the net electric charge enclosed by the pyramid.

The electric flux is given by the equation Φ = q/ε₀, where Φ represents the electric flux, q is the net electric charge enclosed, and ε₀ is the electric constant.

In this case, we have a sphere with a charge of -0.2 x \(10^{(-9)}\) C and a cube with a charge of 0.53 x \(10^{(-9)}\) C inside the pyramid. The net charge enclosed is the sum of the charges of the sphere and the cube: -0.2 x \(10^{(-9)}\) C + 0.53 x \(10^{(-9)}\) C = 0.33 x \(10^{(-9)}\) C.

Now we can calculate the electric flux using the equation Φ = q/ε₀. The electric constant, ε₀, is a known value (approximately 8.85 x \(10^{(-12)}\) C²/N·m²). Plugging in the values, we get Φ = (0.33 x \(10^{(-9)}\) C) / (8.85 x \(10^{(-12)}\) C²/N·m²).
