answer :

force is called the magnetic force of repulsion, and it happens when two magnets have the same poles (either both north or both south) and they push away from each other.

When all the domains in a material are aligned in the same direction, the material becomes strongly magnetized.

explanation :

magnetic domains in the rings were stable and strong enough to resist the force of gravity.

In the case of the levitating rings, the magnetic domains were aligned in such a way that they created a strong magnetic field, which allowed the rings to levitate in mid-air.

tiny regions within ferro magnetic  material that have their own magnetic fields are called magnetic domains.

Magnetic domains in the rings refer to the tiny regions within the ring's ferro magnetic material that have their own magnetic fields.

Answer:

F = 1.25 N

Explanation:

The equation to calculate Gravitational Force is

F = G (m1 . m2) / r^2

where G is gravitational constant, m1 and m2 are the mass of the 2 objects.

So, assuming that the G, m1, m2 is constant, the equation will be

F1 . \(r1^{2}\)= F2 . \(r2^{2}\)

Therefore,

F2 = F1 .  \(r1^{2}\) /      \(r2^{2}\)

And finally we just need to find F2 by inserting this value

The correct answers are a, d, f, g, and h. The net work done on particle 1 by the field is zero because the electric field is uniform, so the electric force acting on particle 1 is constant.

Coulomb force is an electrostatic force of attraction or repulsion between two particles that have an electric charge. It is proportional to the product of the charges and inversely proportional to the square of the distance between them.

The Coulomb force exerted on both particles by the source of the E-field increases as they move from start to finish, but the electrical potential energy of particle 2 does not change from start to finish. The E-field at point A when particle 1 is at point A has less magnitude than the E-field at point C when particle 2 is at point C because the magnitude of the electric field decreases with distance from the source. Both particles are at rest when they reach points A and C respectively, and both particles move through the same potential difference from start to finish. Lastly, the Coulomb force exerted on particle 2 by the source of the E-field is larger in magnitude than the Coulomb force exerted on particle 1 by the source of the E-field since particle 2 is closer to the source of the electric field.

The ratio of a substance's weight, especially a mineral, to an equal volume of water at 4°C is called it's specific gravity or relative density.

Specific gravity is the ratio of the density of a substance to the density of a reference substance, usually water. In simple terms, specific gravity is the density of a substance compared to the density of water. It's a dimensionless amount since it's a ratio. It is frequently used in geology to compare the densities of minerals to those of water.

Specific gravity is calculated by dividing the density of a substance by the density of water. The specific gravity formula is given by:

Specific gravity = (density of substance)

(a) It will take 2 seconds for the ball to pass the man moving in the downward direction.

(b) The maximum height attained by the ball is 20 meters.

(c) The ball will take 2+2\sqrt{2} seconds to hit the ground.

(a) How long will it take the ball to pass the man moving in the downward direction?

We can use the equation of motion:

v = u + at,

where:

v = final velocity (0 m/s since the ball will momentarily stop when passing the man),

u = initial velocity (20 m/s upwards),

a = acceleration (due to gravity, -10 m/s²),

t = time.

Substituting the known values we get:

0 = 20 - 10t.

Simplifying the equation:

10t = 20,

t = 20/10,

t = 2 seconds.

Therefore, it will take 2 seconds for the ball to pass the man moving in the downward direction.

(b) What is the maximum height attained by the ball?

To find the maximum height attained by the ball, we can use the following equation:

v² = u² + 2as,

where:

v = final velocity (0 m/s at the maximum height),

u = initial velocity (20 m/s upwards),

a = acceleration (acceleration due to gravity, -10 m/s²),

s = displacement.

The maximum height will be achieved when v = 0. Rearranging the equation, we get:

0 = (20)² + 2(-10)s.

Simplifying the equation:

400 = -20s.

Dividing both sides by -20:

s = -400/-20,

s = 20 meters.

Therefore, the maximum height attained by the ball is 20 meters.

(c) How long will it take the ball to hit the ground?

To find the time it takes for the ball to hit the ground, we can use the following equation:

s = ut + (1/2)at²,

where:

s = displacement (60 meters downwards),

u = initial velocity (20 m/s upwards),

a = acceleration (acceleration due to gravity, -10 m/s²),

t = time.

Rearranging the equation, we get:

-60 = 20t + (1/2)(-10)t².

Simplifying the equation:

-60 = 20t - 5t².

Rearranging to form a quadratic equation:

5t² - 20t - 60 = 0.

Dividing both sides by 5:

t² - 4t - 12 = 0.

Solving the equation using the quadratic formula, we get:

t = (4 ± sqrt(16 + 4 x 12)) / 2

t = (4 ± 4sqrt(2)) / 2

t = 2 ± 2sqrt(2)

Since time cannot be in negative terms, we ignore the negative value of t.  Therefore, the time it takes for the ball to hit the ground is:

t = 2 + 2sqrt(2) seconds

A spherical aberration in a semicircular lens negatively affects the clarity and sharpness of the image formed due to the imperfect convergence of light rays at the focal point.

The effect of spherical aberration observed in a semicircular lens can be explained as follows: Spherical aberration occurs when light rays entering the lens at different distances from the optical axis do not converge at a single focal point.

In a semicircular lens, this aberration results from the curved shape of the lens surfaces, causing rays parallel to the optical axis to focus at different points along the axis.

The main impact of spherical aberration in a semicircular lens is the distortion and blurring of the image formed, as rays from a single point source are not focused sharply onto a single point on the image plane.

This aberration can be minimized by using an aspherical lens, which has a surface profile designed to eliminate the discrepancies in the focusing of light rays.

The merry-go-round is accelerating since it is moving in a circle despite the fact that it is moving at a constant speed. The fact that an object moves in a circle does not always imply that it is moving at a constant speed. When an object moves in a circle, it changes direction, and this alteration of direction implies that the object is accelerating.

Even if the speed remains constant, it is still accelerating because the velocity is changing. This is referred to as centripetal acceleration. Centripetal acceleration is the acceleration caused by a force that pulls an object towards the center of the circle. Centripetal force is required for a body to move in a circle. A merry-go-round moves in a circle at a constant speed. This implies that the speed of the merry-go-round does not vary. However, the direction of motion changes continuously, indicating that the merry-go-round is constantly accelerating.

The number of bright fringes formed on either side of the central bright fringe can be determined using the formula:

n = (D/L) * (m + 1/2)

Where:

n = number of bright fringes

D = distance between the double slit and the screen

L = wavelength of light

m = order of the fringe

For the central bright fringe, m = 0.

For the first-order bright fringe, m = 1.

The distance between the double slit and the screen is not given in the question. Therefore, we cannot determine the exact number of bright fringes that can be formed on either side of the central bright fringe. However, we can use the maximum value of D/L, which is when sinθ = 1, to estimate the maximum number of bright fringes that can be formed.

For sinθ = 1, θ = 90°.

sinθ = (m + 1/2) * (L/d)

1 = (m + 1/2) * (625 nm/3.76 x 10-6 m)

m + 1/2 = 1.06 x 104

m ≈ 2.12 x 104
