"When the magnitude of the electric field in an EM wave is doubled, the intensity of the wave increases by a factor of 4."

The intensity (I) of an electromagnetic wave is given mathematically as,

I = (1/2) ε₀ c E²

where,

ε₀ is the electric constant

c is the speed of light

E is magnitude of the electric field

An electromagnetic wave's intensity will increase by a factor of four if the electric field's magnitude doubles.

I' = (1/2)ε₀c(2E)² = 4(1/2)ε₀ c E² = 4 I

Electromagnetic waves are waves that are usually produced by oscillating electric and magnetic fields. An electromagnetic wave is a combination of electric and magnetic fields that oscillate perpendicularly to each other and to the direction of wave propagation. Light, microwaves, X-rays, and radio waves are the examples of electromagnetic waves.

The power transferred per unit area by an electromagnetic wave is said to be the intensity of the wave. The magnitude of the electric field in an EM wave is connected with its intensity.

Thus, as the magnitude of the electric field in an EM wave is doubled, the intensity of the wave becomes four times of the value.

When two pieces of silk that have been rubbed on a piece of amber are brought close together, they will experience electrostatic attraction.

The electrostatic attraction is because the rubbing of the amber transfers electrons from the amber to the silk pieces, which creates a net positive charge on one piece and a net negative charge on the other. This results in the positive charge being attracted to the negative charge and the two pieces of silk being attracted to each other. This is due to the electric forces of attraction between particles with opposite charges.

This attraction can be seen through the "Leyden Jar" experiment, where two pieces of glass and two pieces of silk that have been rubbed on a piece of amber are placed on either side of the Leyden Jar. When the two pieces of silk are brought close together, an electric spark is observed. This is a result of the attraction of the opposite charges.

In conclusion, when two pieces of silk that have been rubbed on a piece of amber are brought close together, they will experience electrostatic attraction due to the electric forces of attraction between particles with opposite charges.

The focal length of the lens, in which the image is formed on the opposite side of the object- 68.3cm away from it, is -68.5cm.

The formula for finding the focal length of a lens is:

1/f = 1/di + 1/do

where f is the focal length of the lens, di is the distance from the lens to the image and do is the distance from the lens to the object.

In this case, di = -68.3 cm (since the image is formed on the opposite side of the lens), and do = 27.2 cm. Plugging these values into the formula gives:

1/f = 1/-68.3 + 1/27.2

Simplifying this equation gives:

1/f = -0.0146

Multiplying both sides by -1 gives:

-1/f = 0.0146

Dividing both sides by 0.0146 gives:

f ≈ -68.5 cm

The distance of the screen from the lens is: 0.055 meters

Given the distance of slide from the lens = 110 mm, we need to find the distance of screen from the lens in meters.

According to the lens formula,1/f = 1/v - 1/u
Where, f is the focal length of the lens
v is the distance of the image from the lens
u is the distance of the object from the lens

In this case, the slide is acting as an object and the screen is the image produced by the lens.

Since the image produced is sharp, we can assume that the lens is able to produce a real image.

Hence, v is negative. u = -110 mm = -0.11 m

Using the given formula, we have: 1/f = 1/v - 1/u
Putting v = -v and solving for v, we get:v = -u*f / (u - f)
Putting in the values of u = -0.11 m and f = 40 mm = 0.04 m, we get: v = -(-0.11)*(0.04) / (-0.11 - 0.04) = 0.055 m

When a positive charge is released from rest in an electric field, it moves along an electric field line in the direction of the electric field. The electric field exerts a force on the charge, causing it to accelerate in the direction of the electric field. As the charge moves, it follows the path of the electric field lines, which show the direction of the electric field at every point in space. The path of the charge along the electric field line depends on the configuration of the electric field and the initial position of the charge.

To find the angular acceleration, we can use the formula:

θ = 1/2 * α * t^2

where θ is the angular displacement, t is the time, and α is the angular acceleration.

Rearranging this formula to solve for α, we get:

The formula for acceleration is given by a=Δv/Δt, where a = acceleration (m/s²)Δv = change in velocity (m/s)Δt = change in time (s)To calculate the vertical acceleration of the cylinder, we can use the formula for force, which is given by F = ma, where F = force (N)m = mass (kg)a = acceleration (m/s²) Now, we will calculate the mass of the cylinder using the given weight of wa = 53 lb.1 lb = 0.453592 kg Therefore, wa = 53 lb = 24.0409 kg For the first case, the weight is acting downwards on the cylinder. Therefore, the force on the cylinder can be calculated as F = ma F = 24.0409 kg × 9.8 m/s²F = 236.03 N Now, we can use this force to calculate the acceleration of the cylinder. a = F/ma = 236.03 N/24.0409 kg a = 9.8 m/s²Therefore, the vertical acceleration of the cylinder for the first case is 9.8 m/s², which is positive as it is upwards.

If light passes through a flat surface at a perpendicular angle, there is no change in speed or direction, so the emergent ray travels in a straight line without bending or changing direction.

But in this scenario, the incident ray is directed towards the center of the flat edge of the block, it enters the block perpendicular to the flat surface and emerges from the block at the same angle and direction as the incident ray, without any refraction or change in direction.

A red laser pointer with a wavelength of 650 nm has a width of 3,205,524 km that leaves the laser through a 1.0-mm diameter aperture.

Let's first figure out the diameter of the beam. We know that the aperture of the laser pointer is 1.0 mm in diameter. So, the diameter of the beam leaving the laser is also 1.0 mm.

In this case, we can assume that the laser beam spreads out uniformly in all directions as it travels from Earth to the Moon. Therefore, the diameter of the beam would increase linearly with distance from the source. This increase in diameter is determined by the divergence angle of the beam.

In this case, we can use the following formula to determine the beam diameter after it has traveled a certain distance:

D = D₀ + 2 * L * tan(θ/2)

where D is the diameter of the beam at distance L from the source, D₀ is the diameter of the beam at the source, λ is the wavelength of the light, and θ is the divergence angle of the beam.

As we do not know the divergence angle, we need to make an assumption about it. For a typical laser pointer, the divergence angle can be anywhere between 0.1 and 1 degree. We'll assume a divergence angle of 0.1 degrees, which is on the low end of the range.

Substituting the values we know into the formula, we get:

D = D₀ + 2 * L * tan(θ/2) = 1.0 mm + 2 * 384,000 km * tan(0.1/2) = 3,205,524 km.
