Capacitors are electronic components that store electrical energy. They are made up of two conducting plates separated by an insulating material called a dielectric. When a voltage is applied to a capacitor, it stores a charge in the form of an electric field between the two conducting plates. This stored charge can then be used to provide a current when the voltage is removed. Capacitors are used in a variety of applications including power supplies, filters, oscillators, and motors. They can also be used to store energy for later use, such as providing a short burst of power to a motor or providing a reserve of energy for a power outage.

Answer:

its D

Explanation:

The kinetic energy is the energy of motion.

The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force. After the work is finished, energy is transferred to the item, which then moves at a new, constant speed.

An item in motion has energy, which is called kinetic energy. Motion in space, you walking down the street, and the rotation of the planet around the sun are all examples of kinetic energy. Kinetic energy has the following formula: K.E. = 1/2 m*v², where m is the object's mass and v is its square velocity.

Any object in motion is using kinetic energy, so the energy of motion is

The classification of stars based on their spectral type follows the sequence O, B, A, F, G, K, and M, with O-type stars being the hottest and M-type stars being the coolest. The habitable zone, also known as the "Goldilocks zone," refers to the region around a star where conditions may be suitable for the existence of liquid water on the surface of a planet.

G-type stars, such as our Sun (classified as G2V), are considered to be within the optimal range for habitability. These stars have a stable and long-lasting main sequence phase, providing a relatively steady energy output over billions of years. Planets orbiting within the habitable zone of a G-type star have the potential to maintain a stable climate, with the right conditions for liquid water to exist. While other star types like F-type, K-type, and even some M-type stars can have habitable zones, G-type stars are generally considered to provide more favourable conditions for life.

The number of resistors in circuit 1 = 1 resistor

The number of resistors in circuit 2 = 2 resistors

Let 'R' represent the value of each resistor, we have;

The total resistance of circuit 1 = R Ohm

∴ The total resistance of circuit 1  = (1/2) × The total resistance of circuit 3

∴ The resistance of circuit 1 is half the resistance of circuit 3

(ii) The potential difference of each cell, V = 1.5 volts

The number of cells in circuit 2 = 2 cells

The total potential difference of the cells of circuit 2 = 2 × 1.5 volts = 3 × volts = 3 V.

The voltmeter reading = The potential difference across the cell or cells it is applied

∴ The voltmeter reading on voltmeter, V₂, applied across the cells of circuit 2 = 3 V

(iii) The voltmeter reading V₁ = 1.5 V

The voltmeter reading V₂ = 3 V

The voltmeter reading V₃ = 4.5/(2·R) × R = 2.25 V

Therefore, the voltmeter reading with the smallest volt, is V₁ = 1.5 V

Let w denote the weight of the box, n the magnitude of the normal force (the sheet pushing up on the box), k the magnitude of the kinetic friction force, and µ the coefficient of kinetic friction.

The kinetic friction force doesn't kick in until the sheet is tilted at an angle θ₂. Since the box is sliding down at constant speed, it's in equilibrium and the forces acting on it sum to 0.

In the horizontal direction (literally left-and-right, parallel to the ground and not the sheet), we have only the horizontal components of the friction and normal forces to worry about, so that \(\mathbf n_x+\mathbf f_x=\mathbf0\), which reduces to

f cos(θ₂) + n cos(90º + θ₂) = 0

(where we take the right to be positive and left to be negative)

Recall that cos(90º + x) = -sin(x) for all x, and that the friction force is proportional to the normal force by a factor of µ. This gives

µ n cos(θ₂) - n sin(θ₂) = 0

Solve for µ :

µ n cos(θ₂) = n sin(θ₂)

µ = sin(θ₂) / cos(θ₂)

µ = tan(θ₂)

The main answer is: The cheese will cause the spring to compress due to its weight.

When the cheese is placed on the vertical spring, it exerts a downward force due to its weight. This force causes the spring to compress. The spring constant, denoted by k, determines how much the spring will compress in response to the applied force. Since the mass of the cheese is given as 1.50 kg, the force exerted by the cheese due to its weight can be calculated using the equation F = mg, where m is the mass of the cheese and g is the acceleration due to gravity. This downward force causes the spring to compress, resulting in a change in the length of the spring from its equilibrium position. The specific amount of compression can be determined by the relationship between the force constant of the spring and the applied force.

In order to fully analyze the system, additional information is required, such as the value of the spring constant k. The spring constant represents the stiffness of the spring and determines how much force is needed to produce a given displacement or compression in the spring. Once the value of the spring constant is known, Hooke's Law can be applied to calculate the amount of compression in the spring. Hooke's Law states that the force exerted by a spring is directly proportional to the displacement or compression of the spring from its equilibrium position. Mathematically, this can be expressed as F = -kx, where F is the force exerted by the spring, k is the spring constant, and x is the displacement or compression of the spring. By rearranging the equation, the compression of the spring, denoted by x, can be calculated as x = -F/k. Therefore, with the value of the downward force exerted by the cheese and the spring constant, the compression of the spring can be determined.

Answer:

2.605m

Explanation:

Using the formula for calculating Range (distance travelled in horizontal direction)

Range R = U√2H/g

U is the speed = 4.8m/s

H is the maximum height = ?

g is the acc due to gravity = 9.8m/s²

R = 3.5m

Substitute into the formula and get H

3.5 = 4.8√2H/9.8

3.5/4.8 = √2H/9.8

0.7292 = √2H/9.8

square both sides

0.7292² = 2H/9.8

2H = 0.7292² * 9.8

2H = 5.21

H = 5.21/2

H = 2.605m

Hence the height of the ball from the ground is 2.605m

The current through the bottom of the wire is 0.415 A and the negative sign of the current indicates that current flows from left to right from the bottom wire.

The current through various parts of the circuit is as shown in figure.

Here we have to calculate the current I_5.

Applying Kirchoff's loop rule on each of the loops in the circuit, Consider the left triangle, for it, we have

\($$\begin{aligned}& \left(I_1\right) 6 \Omega+\left(I_3\right) 12 \Omega-9 \mathrm{~V}=0 \\& \Rightarrow 6 I_1+12 I_3=9 \\& \Rightarrow I_1=\frac{9}{6}-\frac{12}{6} I_3 \\& \Rightarrow I_1=1.5-2 I_3-----(1)\end{aligned}$$\)

For the centre of the triangle, we have

\($$\begin{aligned}& \left(I_4\right) 24 \Omega-\left(I_3\right) 12 \Omega=0 \\& \Rightarrow I_4=\frac{12}{24} I_3 \\& \Rightarrow I_4=\frac{I_3}{2}-----(2)\end{aligned}$$\)

And for the right triangle, we have

\($$\begin{aligned}& \left(I_2\right) 10 \Omega+\left(I_4\right) 24 \Omega-15 \mathrm{~V}=0 \\& \Rightarrow I_2=\frac{15}{10}-\frac{24}{10} I_4 \\& \Rightarrow I_2=1.5-2.4 I_4------(3)\end{aligned}$$\)

The junction rule applied at the left corner gives

I_1  =I_3+I_5

=I_5  =I_1-I_3

=1.5-2 I_3-(I_3)=1.5-3 I_3--------(4)

And applying the junction rule at the right corner,

I_4 =I_2+I_5

I_5 =I_4-I_2

=I_4-(1.5-2.4 I_4)=3.4 I_4-1.5-------(5)

Using equation (2) \($I_4=\frac{I_3}{2}$\), equation (5) can be written as

\($$\begin{aligned}I_5 & =3.4\left(\frac{I_3}{2}\right)-1.5 \\\end{aligned}$$\)==1.7 I_3-1.5

Solving equations (4) and (6), we have

1.5-3 I_3=1.7 I_3-1.5

(1.5+1.5)=(1.7+3.0) I_3

3.0=4.7 I_3

\(\Rightarrow I_3=\frac{3.0}{4.7} \mathrm{~A}\)

Hence the current in the bottom wire is given by

\(I_5 & =1.7\left(\frac{3.0}{4.7}\right)-1.5 \\\) =1.085-1.5 =-0.415 A

a. The frequency of the 500 nm radiation is  6x10⁻¹⁴ s⁻¹.

b. The work function for the material can be determined using the equation W = hf - eV, where W is the work function, h is Planck's constant, f is the frequency of the radiation, and eV is the energy necessary to stop the photoelectrons from reaching the anode. In this case, eV = 3 V, so W = 6.63x10⁻³⁴ x 6x10¹⁴ - 3 = 1.890 x 10⁻¹⁹ J.

c. The energy of the photons associated with the unknown wavelength can be determined by using the equation E = hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency of the radiation. Since we do not know the frequency of the unknown wavelength, we can use the equation E = hc/lambda, where c is the speed of light and lambda is the wavelength of the radiation. Since we are given that the potential required to stop the photoelectrons is 3V, we can calculate the energy of the photon as E = 3/1.6x10¹⁹ = 1.875 x 10⁻¹⁸ J.

d. The unknown wavelength can be determined using the equation lambda = hc/E, where h is Planck's constant, c is the speed of light, and E is the energy of the photon. Substituting the values, we get lambda = 6.63x10⁻³⁴ x 3x10⁸/1.875 x 10 = 7.8 x 10⁻⁷ m, or 780 nm.

The attraction or repulsion that occurs when magnets are held close to each other is caused by magnetic fields.

When a magnet is brought close to another magnet, the magnetic field of the first magnet interacts with the magnetic field of the second magnet. These magnetic fields are created by the motion of electric charges within the magnets, such as the motion of electrons in the atoms that make up the material of the magnets.

The magnetic fields can either reinforce or cancel each other out, depending on their orientation and strength, which leads to the attraction or repulsion between the two magnets.
