The potential of an infinite uniform line charge (lambda) is given by V(r) = lambda/(2πε*r), where ε is the permittivity of free space, and r is the distance from the line charge.

An infinite uniform line charge is a theoretical concept where a line of infinite length has a uniform charge density along its length. The potential of this line charge can be calculated using Coulomb's law, where the potential due to a point charge at a distance r is proportional to the charge and inversely proportional to the distance.

In this case, the line charge has an infinite length, so it can be considered as an infinite number of point charges. By summing up the potential due to each point charge, we can find the potential of the entire line charge. The result shows that the potential of an infinite uniform line charge is inversely proportional to the distance from the line charge, which satisfies the Laplacian equation.

T=2()m/k is the formula for the general relationship of oscillation T of a mass m hung on a spring. T is equal to 2 () m / k, with k denoting the spring constant.

The frequency of the oscillation must drop if the size of a simple chromatic oscillator is increased while keeping everything else constant. The oscillator will accelerate more slowly as a result. On the other hand, frequency will rise if the constant of proportionality K is raised.

Consider a spring with an upstretched length l, a spring constant of k, and a mass M descending from it. The resonance frequency would be k/M if the spring's mass were ignored shows that the spring mass's impact would be to change M in the calculation for to M + m/3.

The amount of work done by the electrostatic force on the charged particle as it moves along the straight path from B to A is equal to the force of the electrostatic field, multiplied by the displacement of the particle along the path.

Mathematically, this can be represented as WBA = F * d, where F is the electrostatic force and d is the displacement of the particle.

Work is a concept used in physics to describe the transfer of energy from one object to another. It is defined as the force applied over a distance and is usually measured in joules (J). When a force acts on an object, it causes the object to move or to change its shape, and this energy is transferred from the force to the object.

Work can be positive, in which case the object gains energy, or negative, in which case the object loses energy. Work can also be done on an object without it actually moving, such as when a force is applied to stretch or compress the object.

The acceleration is 0.10m/s2 when  a car originally traveling at 50.0 km/h in the positive direction accelerates at a rate of -0.400 m/s2 for 50.0 s.

Given the initial velocity of car (u)= 50km/h = 50 x 5/18 = 13.8m/s

The car accelerates at a rate = -0.400m/s2

The time taken to accelerate (t) = 50s

Let the final velocity = v

We know that from Newtons laws of Motion:

a = dv/dt = v - u/t

-0.400 x 50 = v - 13.8

v = 6.2m/s

The distance travelled = [tex]s = ut + 1/2at^2[/tex]

Then s = 13.8 x 50 - 1/2 x 0.4 x 50 x 50 = 190m

The final velocity of the car is 6.2m/s and as the acceleration remains constant during the travel which is equal to [tex]v^2 = 2as[/tex]

Torque can be defined as the rotational equivalent of the linear force. Torque is also referred to as the moment of any force. Torque represents the capability of a force to produce change in the rotational motion of the object.

I = mR²/ 2

As we already know, kinematics equation is:

As a result, the ball will reach a maximum height of 0.826 m above the release point.

In the absence of force, the item would naturally rest in the equilibrium position. The biggest deviation from equilibrium is referred to as the amplitude X. The units for amplitude and displacement are the same, but the kind of oscillation affects them.

Here,

When the ball is released from rest, it will start moving straight up due to the potential energy stored in the compressed spring. The ball's initial velocity can be calculated using the equation of motion:

v_initial = sqrt(2 * k * x / m)

where k is the spring constant, x is the compression distance, and m is the mass of the ball.

v_initial = sqrt(2 * 75 N/m * 0.25 m / 0.250 kg) = 6.13 m/s

The maximum height that the ball reaches can be calculated using the conservation of energy:

h = v_initial^2 / (2 * g)

where g is the acceleration due to gravity.

h = (6.13 m/s)^2 / (2 * 9.8 m/s^2) = 0.826 m

Electric current is described as a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space which is measured as the net rate of flow of electric charge through a surface or into a control volume.

Current = Charge x Rate of flow of charges

Rate of flow of charges = Total rate of flow of negative charges - Total rate of flow of positive charges

The total rate of flow of negative charges is 362 x 10^6 ions per minute and the total rate of flow of positive charges is 5.83 x 10^2 ions per minute.

Rate of flow of charges = 362 x 10^6 - 5.83 x 10^2 = 361.9994 x 10^6 ions per minute

The atmospheric window is the atmospheric window of wavelengths of longwave radiation that escape to space is fairly narrow, at 8 to 15 microns.

The atmospheric window is the atmospheric window of wavelengths of longwave radiation that escape to space is fairly narrow, at 8 to 15 microns. This window is important because it allows the Earth to cool down by radiating excess heat into space. Longwave radiation is also known as terrestrial radiation or infrared radiation, and it is produced by the Earth's surface and the atmosphere.

The narrow range of wavelengths that make up the atmospheric window is critical because it allows the radiation to pass through the Earth's atmosphere with minimal absorption. If the atmospheric window were wider, more of the radiation would be absorbed by the atmosphere, and the Earth would not be able to effectively cool down.

The composition of the atmosphere and the amount of greenhouse gases it contains can impact the atmospheric window. For example, an increase in the concentration of greenhouse gases can trap more radiation in the atmosphere, reducing the size of the atmospheric window.
