5. How will you separate water from petrol?

Answer:

A attractive field pulls and pushes electrons in certain objects closer to them, making them move. Metals like copper have electrons that are effortlessly moved from their circles. In case you move a magnet rapidly through a coil of copper wire, the electrons will move - this produces power.

The electric flux through the given surface is 1,659.6 N m2/C.



Electric flux is defined as the product of the electric field passing through a surface and the area of that surface. Mathematically, electric flux (Φ) is given by Φ = E · A · cosθ, where E is the electric field strength, A is the area of the surface and θ is the angle between the electric field and the surface.

In the given problem, the electric field strength is E = 480 N/C, the area of the surface is A = 3.45 m2 and the angle between the electric field and the surface is θ = 60.5°.

Using the formula for electric flux, we get:

Φ = E · A · cosθ

Φ = 480 N/C · 3.45 m2 · cos60.5°

Φ = 1659.6 N m2/C

Therefore, the electric flux through the given surface is 1,659.6 N m2/C.



The concept of electric flux is very important in the study of electricity and magnetism. It helps us to understand how electric fields interact with surfaces and how electric charges can be distributed on surfaces.

In this problem, we are given a uniform electric field of magnitude E = 480 N/C that makes an angle of θ = 60.5° with a plane surface of area A = 3.45 m2. We are asked to find the electric flux through this surface.

To solve this problem, we need to use the formula for electric flux: Φ = E · A · cosθ. This formula tells us that the electric flux through a surface depends on the strength of the electric field, the area of the surface and the angle between the electric field and the surface.

First, let's find the component of the electric field that is perpendicular to the surface. This component is given by E⊥ = E · cosθ. Substituting the given values, we get:

E⊥ = 480 N/C · cos60.5°

E⊥ = 240 N/C

Next, we can use this value to calculate the electric flux through the surface:

Φ = E⊥ · A

Φ = 240 N/C · 3.45 m2

Φ = 829.2 N m2/C

However, this is not the final answer. We need to take into account the fact that the electric field makes an angle with the surface. When the electric field is not perpendicular to the surface, the electric flux is reduced by a factor of cosθ. Therefore, we need to multiply our previous result by cosθ to get the final answer:

Φ = E⊥ · A · cosθ

Φ = 240 N/C · 3.45 m2 · cos60.5°

Φ = 1659.6 N m2/C

Therefore, the electric flux through the given surface is 1,659.6 N m2/C.

The length of the tungsten wire is 13.7 cm.

To find the length of the tungsten wire, we need to first find its volume. We know the density of tungsten, which is 19.25 g/cm³, and the mass, which is 39.7 g. We can use the formula for the volume of a cylinder, which is πr²h, where r is the radius and h is the height (which is equal to the length of the wire in this case).

First, we'll find the volume:

V = πr²h

V = π (3.79 mm)²h

V = 11.05 mm³h

Next, we'll convert the volume to cubic centimeters (cm³):

11.05 mm³ = 11.05 x 10^-9 cm³

Now that we have the volume in cm³, we can use the density formula to find the mass:

m = ρV

m = 19.25 g/cm³ x 11.05 x 10^-9 cm³

m = 0.2103 g

Finally, we'll use the mass and density to find the length:

m = ρV

0.2103 g = 19.25 g/cm³ x V

V = 0.2103 g / 19.25 g/cm³

V = 0.0109 cm³

And since the volume is equal to πr²h, we can find the height (which is the length of the wire) by rearranging the formula:

V = πr²h

h = V / πr²

h = 0.0109 cm³ / π (3.79 mm)²

h = 13.7 cm

So the length of the tungsten wire is 13.7 cm.

Displacement in unit vector is  85i + 85j.

When moving from one location to another, the displacement vector resembles an arrow, with its tip at the second point and its tail at the first. The length of the arrow is a symbol for the displacement vector's magnitude, which represents the distance between the locations.

Calculation:

The mathematical notation for the displacement vector R is given by

R cosφi + R sinφj

Now a bird flies straight northeast a distance of 95.0 km for 3.0 h such that x-axis points towards east and the y-axis points towards north.

Now put R = 95 and φ =  45

95.0 cos 45°i + 95.0 sin j  = 95.0i / √2 + 95.0j / √2  =  85i + 85j

Answer:

It is A when the firework explodes it creates heat and which makes different colors

Explanation:

(a) The impulse reaction of the gadget is h(n) = δ(n+1) + δ(n-1). (b) The system is causal due to the fact the output simplest relies upon present and beyond inputs, x(n+1) and x(n-1), respectively. (c) The system is linear because it satisfies the homes of superposition and homogeneity.

(d) This is an IIR (Infinite Impulse Response) filter out because the output relies upon beyond inputs. (e) The frequency response of the machine is H(z) = \(z^(-1) + z\). (f) The device is BIBO strong considering its miles are linear and causal, and its impulse response is finite, ensuring bounded output for bounded enter.

(a) To discover the impulse reaction of the gadget, we want to enter an impulse signal. An impulse signal is represented as δ(n), that is 1 at n = 0 and 0 for all different values of n.

Let's alternative δ(n) into the given equation:

y(n) = x(n+1) + x(n-1)

For n = 0:

y(0) = x(1) + x(-1)

For n = 1:

y(1) = x(2) + x(0)

For n = -1:

y(-1) = x(0) + x(-2)

For n ≠ 0, 1, -1, y(n) = 0 considering the fact that x(n) = 0.

So, the impulse reaction of the gadget is:

h(n) = δ(n+1) + δ(n-1)

(b) The machine is causal if the output y(n) relies upon only on the present and beyond inputs x(n), x(n-1), x(n-2), and so forth. In this case, due to the fact that y(n) simplest depends on x(n+1) and x(n-1), it does not depend on future inputs. Therefore, the machine is causal.

(c) The system is linear if it satisfies the properties of superposition and homogeneity. Let's confirm these houses:

Superposition:

For two inputs \(x1(n)\)and \(x2(n)\) their corresponding outputs \(y1(n)\) , \(y2(n)\), we've got:

\(y1(n) = x1(n+1) + x1(n-1)\)

\(y2(n) = x2(n+1) + x2(n-1)\)

Now, allow's apply the machine to the linear aggregate of inputs:

\(y(n) = ax1(n) + bx2(n)\)

=\(a(x1(n+1) + x1(n-1)) + b(x2(n+1) + x2(n-1))\)

= \(ax1(n+1) + ax1(n-1) + bx2(n+1) + bx2(n-1)\)

This fits the output received when the system is carried out to the linear mixture of the person inputs. Therefore, the device is linear.

(d) This is an IIR (Infinite Impulse Response) clear out due to the fact the output depends on each contemporary and past input, as visible inside the equation y(n) = x(n+1) + x(n-1).

(e) To locate the frequency response, we will take the Z-remodel of the gadget's impulse response. Applying the Z-transform to the impulse response h(n) = δ(n+1) + δ(n-1), we get:

H(z) =\(Zh(n) = z^(-1) + z\)

The frequency response of the device is the Z-transform of the impulse reaction.

(f) BIBO (Bounded-Input Bounded-Output) stability refers to the belongings of the device to produce bounded output for any bounded input. In this example, because the system is linear and causal, and the impulse reaction is finite, the device is BIBO stable.

Explanation:

Potential energy is energy an object has because of its position relative to some other object. ... Notice that gravitational potential energy has the same units as kinetic energy, kg m2 / s2. In fact, all energy has the same units, kg m2 / s2, and is measured using the unit Joule (J).

We find that the change in kinetic energy is positive and equal to 696.60 W, option d. The formula for kinetic energy is given by KE = 1/2 * mv^2, where m is the mass of the fluid and v is its velocity.

In this case, we are given the velocities at the outlet and the reactor inlet, which are 14.4 m/s and 10.7 m/s, respectively. Since the mass of the fluid is not provided, we can assume it to be constant.

The change in kinetic energy is given by the difference in kinetic energies at the outlet and the reactor inlet, which can be calculated using the formula:

ΔKE = (1/2 * m * v_outlet^2) - (1/2 * m * v_inlet^2)

Simplifying this expression, we get:

ΔKE = 1/2 * m * (v_outlet^2 - v_inlet^2)

Plugging in the given values, we have:

ΔKE = 1/2 * m * (14.4^2 - 10.7^2)

Calculating this expression, we find the answer to be approximately 696.60 W. Therefore, the correct option is d. 696.60.

In summary, the change in the rate of kinetic energy is approximately 696.60 W. This is calculated by taking the difference between the kinetic energy at the outlet and the kinetic energy at the reactor inlet using the formula ΔKE = 1/2 * m * (v_outlet^2 - v_inlet^2). Plugging in the given velocities of 14.4 m/s and 10.7 m/s, we find that the change in kinetic energy is positive and equal to 696.60 W.

Despite being massless, photons do have momentum, and it is directly related to their wavelength. This relationship is described by the equation p = λ, where p is the momentum of the photon, λ is its wavelength, and h is Planck's constant. This relationship was first proposed by Einstein in his theory of the photoelectric effect. The correct answer is (d).

The fact that photons have momentum has been demonstrated through various experiments, such as the Compton scattering experiment, which showed that photons can transfer momentum to electrons. The momentum of photons is also important in understanding phenomena such as the Doppler effect, where the wavelength of light is affected by the motion of the source or observer.

It is important to note that while photons have momentum, they do not have mass, which sets them apart from other particles such as electrons. This means that the momentum of a photon cannot be calculated using the classical formula p = mv, where m is the mass of the particle and v is its velocity. Instead, the momentum of a photon is entirely determined by its wavelength.

In summary, while photons are massless, they do have momentum, which is related to their wavelength through the equation p = λ. This relationship has been demonstrated through various experiments and is an important aspect of understanding the behavior of light.

The moment through the center of the pipe (A) due to the force equal to 39 pounds exerted by the wrench is 234 lb-inches to the nearest hundredth.

To determine the moment through the center of the pipe (A) due to the force equal to 39 pounds exerted by the wrench,

the formula to be used is M = F × d,

where M represents moment, F represents force, and d represents distance. When calculating moments, it is essential to use the correct sign convention. The clockwise moments are considered negative while anticlockwise moments are considered positive. A moment is a measure of a force's tendency to create rotational movement about an axis or point. When an object is exposed to a force that causes it to turn around a point, a moment is created, and the object is said to experience a moment.

To solve the problem, we must first identify the distance from the force to the center of the pipe, which is denoted by d. The diagram above shows that the force is 6 inches away from the center of the pipe, with the wrench applying the force at the 3-inch mark. Thus, d is equal to 6 inches.

The angle theta in the given scenario can be determined by considering the forces acting on the small spherical insulator. The correct answer is 1.30∘.

The gravitational force acting on the small spherical insulator is balanced by the tension in the wire. Additionally, there is an electrostatic force between the charges.

The electrostatic force can be calculated using Coulomb's Law:

F = k * |q1 * q2| / \(r^2\)

where F is the force, k is the electrostatic constant, q1 and q2 are the charges, and r is the distance between the charges.

In this case, the electrostatic force acts horizontally and must be balanced by the horizontal component of the tension in the wire. The vertical component of the tension balances the gravitational force.

Setting up the equilibrium condition, we can find the angle theta(θ):

tan(θ) = (horizontal component of tension) / (vertical component of tension)

tan(θ) = (electrostatic force) / (gravitational force)

Substituting the values given in the problem, we can calculate theta:

tan(θ) = [(k * |q1 * q2|) / \(r^2\)] / (m * g)

tan(θ) = [(8.99×\(10^9\) N · \(m^2/C^2\)) * (0.220 μC) * (0.400 μC)] / [(6.00×\(10^-^2\) kg) * (9.81 m/\(s^2\)) *\((0.290 m)^2\)]
