Answer:

The value is  \(\rho_s = 4.026 *10^{-6} \ C/m^2\)

Explanation:

From the question we are told that

   The radius of the inner conductor  is  \(r_1 = 1 \ mm = 0.001 \ m\)

    The radius of the outer conductor is  \(r_2 = 3 \ mm = 0.003 \ m\)

    The potential at the outer conductor is  \(V = 1.5 kV = 1.5 *10^{3} \ V\)

Generally the capacitance per length of the capacitor like set up of the two conductors is

      \(C= \frac{2 * \pi * \epsilon_o }{ ln [\frac{r_2}{r_1} ]}\)

Here \(\epsilon_o\) is the permitivity of free space with value  \(\epsilon_o = 8.85*10^{-12} C/(V \cdot m)\)

=>   \(C= \frac{2 * 3.142 * 8.85*10^{-12} }{ ln [\frac{0.003}{0.001} ]}\)

=>   \(C= 50.6 *10^{-12} \ F/m\)

Generally given that the potential  of the outer conductor with respect to the inner conductor is positive it then mean that the outer conductor is positively charge

Generally the line  charge density of the outer  conductor is mathematically represented as

      \(\rho_l = C * V\)

=>   \(\rho_d = 50.6*10^{-12} * 1.5*10^{3}\)

=>   \(\rho_d = 7.59*10^{-8} \ C/m\)

Generally the surface charge density is mathematically represented as

        \(\rho_s = \frac{\rho_l }{2 \pi * r_2 }\)    here \(2 \pi r = (circumference \ of \ outer \ conductor )\)

=>    \(\rho_s = \frac{7.59 *10^{-8} }{2* 3.142 * 0.003 }\)

=>    \(\rho_s = 4.026 *10^{-6} \ C/m^2\)

Based on the information provided, it is likely that the figure shows an alternating current (AC). The arrows under the electrons pointing right and left, both towards and away from the light bulb, indicate that the direction of the electron flow is changing periodically. This is a characteristic of alternating current, where the flow of electric charge reverses direction periodically, typically in a sinusoidal manner.

In an AC circuit, the voltage also changes direction periodically, which is consistent with the changing direction of the electron flow shown in the figure.

In an alternating current, the flow of electrons periodically reverses direction, causing the current to switch between positive and negative values. This is different from direct current (DC), where electrons flow in a single, constant direction.

Answer:

The initial velocity of Billy is 66.6 m/s.

Explanation:

Given;

acceleration of Billy, a = 12.3 m/s²

distance moved by Billy, d = 455 m

final velocity of Billy, v = 125 m/s

let the initial velocity of Billy = u

Apply the following equation of motion;

v² = u² + 2ad

125² = u² + 2(12.3 x 455)

15625 = u² + 11193

u² = 15625 - 11193

u² = 4432

u = √4432

u = 66.57 m/s

u = 66.6 m/s.

Therefore, the initial velocity of Billy is 66.6 m/s.

The fourth ellipse, with the length-to-width ratio of approximately 3 to 1, has the greatest eccentricity.

Eccentricity of the ellipse: The eccentricity of an ellipse is a measure of its "oblateness" or how much it deviates from being a circle. An ellipse has an eccentricity between 0 and 1, with 0 representing a circle and values closer to 1 representing more elongated ellipses. So, in this case, the fourth ellipse with the highest length-to-width ratio would have the highest eccentricity value.

The first ellipse is a circle, it means its length-to-width ratio is 1. Second one is more closer to a circle than the third one. Similarly third ellipse is more closer to the circle than the fourth one.

Answer:

2.94 s

Explanation:

v = u + at

where:

v = final velocity = 9 m/s

u = initial velocity = 0 m/s (rest)

a = acceleration

t = time taken to reach final velocity

We can rearrange the equation to solve for time:

t = (v - u) / a

Substituting the given values, we get:

t = (9 m/s - 0 m/s) / a

Now, we need to find the acceleration. We can use another kinematic equation:

s = ut + (1/2)at^2

where:

s = displacement = 1500 m

u = initial velocity = 0 m/s

a = acceleration

t = time taken to cover the displacement

We can rearrange the equation to solve for acceleration:

a = 2(s - ut) / t^2

Substituting the given values, we get:

a = 2(1500 m - 0 m) / (1500 m / 9 m/s)^2

Simplifying, we get:

a = 3.06 m/s^2

Now, we can substitute this value of acceleration in the earlier equation to find the time taken:

t = (9 m/s - 0 m/s) / 3.06 m/s^2

Simplifying, we get:

t = 2.94 s

Answer:

Because 'distance per second' is a velocity, not an acceleration.

Explanation:

Because 'distance per second' is a velocity, not an acceleration. For example, at 1 m/s an object is travelling a distance of 1 metre every second. But a rate of acceleration is a steady increase in velocity. So at 1 m/s^2, an object's velocity is increasing by 1 m/s every second.

Answer:

The period of this pendulum is \(T=1.55\: s\)

Explanation:

The equation of motion of a pendulum is given by:

\(\frac{d\theta^{2}}{dt^{2}}+\frac{g}{L}sin(\theta)=0\) (1)

Where:

θ is the angle of motion

g is the gravity at the earth surface (9.81 m/s²)

L is the length of the pendulum (0.6 m)

Now, using equation (1) we can find the square angular frequency (ω), it will be:

\(\omega^{2}=\frac{g}{L}\)

\(\omega=\sqrt{\frac{g}{L}}\)

Let's recall that the angular frequency is \(\omega=\frac{2\pi}{T}\), then the period will be:

\(T=\frac{2\pi}{\omega}\)  

\(T={2\pi}\sqrt{\frac{L}{g}\)

\(T=2\pi}\sqrt{\frac{0.6}{9.81}\)

Therefore, the period of this pendulum is \(T=1.55\: s\)

Answer:

Explanation:

Answer:

The  velocity  is \(v_2 = 0.96 \ ft/s\)

Explanation:

From the question we are told that

   The initial speed is  \(v_1 = 4 \ ft/s\)

   The  cross -sectional area of the first pipe is  \(A_1 = 15.7 \ ft\)

   The  cross -sectional area of the second pipe is \(A_2 = 65.4 \ ft\)

Generally from continuity equation we have that

     \(A_1 * v_1 = A_2 * v_2\)

So  

     \(v_2 = \frac{A_1 * v_1 }{A_2 }\)

=>   \(v_2 = \frac{15.7 * 4 }{65.4 }\)

=>   \(v_2 = 0.96 \ ft/s\)

65.78meters does the sled travel on the level surface before coming to a rest.

Final speed = 7 m/s

Coefficient of kinetic friction = 0.042

Weight of girl and sled together = 764 Newton

Acceleration of gravity = 9.8 m/s².

To find how far (distance) the sled travel on the level  ground before coming to a rest:

Mathematically, the force of kinetic friction is given by the formula;

\($F_k=u m g$\).........(1)

Where;

F_k represents the force of kinetic friction.

μ represents the coefficient of friction.

m represents the mass.

g is the acceleration due to gravity.

The decelerating force exerted on the sled is given by the formula:

\($F=-m a$\)  ........(2)

First of all, we would determine the deceleration of the sled before coming to a rest.

Equating the two equations, we have:

\($u m g=-m a$\)

\($a=-u g$\)

Substituting the given parameters into the formula, we have;

a =-  0.042*9.8

a= -\($0^2=7^2+2(-0.0.4116) S$\)0.4116m/s²

Now, we can determine how far (distance) the sled traveled by using the third equation of motion;

\($V^2=U^2+2 a S$\)

\($0^2=7^2+2(-0.3724) S$\)

= 49- 0.7448 s

s=65.78meters.
