The bullet's flight time with zero air resistance is 0.065s and the bullet speed as soon as it leaves the barrel is 692.3m/s.

To calculate flight time of the bullet we apply the formula [tex]h = \frac{1}{2} gt^{2}[/tex]

Where h = vertical displacement of bullet in meters, 2.1cm to 0.021m

g = is a gravitational constant of 9.8

t = time of flight in seconds

To find t =

[tex]t = \sqrt{\frac{2h}{g} }[/tex]

[tex]t = \sqrt{\frac{2 * 0.021}{9.8} }[/tex] = [tex]t = \sqrt{\frac{0.042}{9.8} }[/tex]

[tex]t = \sqrt{0.004286}[/tex]

t = 0.065s

For speed of bullet:

[tex]v = \frac{s}{t}[/tex]

Where v = velocity

s = horizontal distance/range of target, 45m

t = flight time in seconds, 0.065s

[tex]v = \frac{45}{0.065}[/tex]

v = 692.3m/s

The bullet's flight time on a horizontal target at 45m from the formula [tex]h = \frac{1}{2} gt^{2}[/tex] is 0.065s and using the time of flight to divide the range, the bullet leaves the barrel at a speed of 692.3m/s

The Focal length (f) exceeds the Object distance (s).

1/v + 1/u = 1/f

As we can see in the fig. the magnitude of the object distance (u) is less than the magnitude of the image distance (v).

Also; u = - u & v = v {distance in the left of the lens is taken -ve.}.

Substituting in eqn (i) :

1/v - 1/u. = 1/f.  ; &  |v.| > |u|

1/v = 1/f + 1/u

Now; In order to be v greatest, 1/v should be smallest.

So, 1/f + 1/u should be smallest  : NOTE : f is a fixed quantity, so value of 1/f can't be changed.

For 1/f + 1/u to be smallest, value of u must be larger.

So the Object distance (s) is larger than the Focal length (f).

The laser beam when passes from medium 1 to medium 2 shows the relation n1 > n2 that is option B is correct.

The laser beam in the attached figure when passing from medium 1 to medium 2 bends away from the normal. This means that the speed of the light beam is increased when it passes from medium 1 to medium 2. This means that the light beam is travelling from a slightly denser medium to slightly rarer medium as it is the property of light beam when it travels from denser to rarer medium it bends away from the normal. The refractive index of denser medium is more than that of the refractive index of rarer medium. So, we can conclude that n1 > n2.

Part a: Displacement current: I(d1) = 8 ampere.

Part b: displacement current: I(d2) = 2.812 x 10⁻¹ A.

Part c: magnetic field at a r = 3 cm radial distance:  1.875 x 10⁻⁶ T.

Part a: Displacement current within the 21 cm-radius circular loop.

Since the capacitance plate has a 16 cm radius, the current can only flow in a loop of this size, or the total displacement current flows within a loop with a 21 cm radius.

Displacement current;

I(d1) = ∈₀.dФ(e)/dt

I(d1) = ∈₀ x A x (Qr.d/∈₀.A.d)

I(d1) = Qr

I(d1) = 8 C/s

I(d1) = 8 ampere of Displacement current.

Part b: displacement current flowing through a 3 cm-diameter circular loop

Density of the displacement current;

Jd = I(d1)/A

Jd = 8/(8.042 x 10⁻²)

Jd = 99.478 A/m²

For the radius r, area of loop

A1 = πr²

A1 = 3.14 x (0.03)²

A1 = 2.827 x 10⁻³ m²

Thus, displacement current;

I(d2) = Jd x A1

I(d2) = 99.478 x 2.827 x 10⁻³

I(d2) = 2.812 x 10⁻¹ A.

Part c: magnetic field at a r = 3 cm radial distance.

Field of magnetism:

B = μ₀.I(d2) / 2πr

B = 4π x 10⁻⁷ x 2.812 x 10⁻¹ / 2π x 0.03

B = 1.875 x 10⁻⁶ T

Thus, magnetic field at a r = 3 cm radial distance is 1.875 x 10⁻⁶ T.

Since the electric field is proportional to the size of the electric charge, which is always positive, it can never be negative. It is directly related to the size of a charge.

Additionally, as the charge is moved further away, the electric field's strength weakens. Electric field is the Force that a charge experiences divided by the amount of the charge. Thus, we consider the mod of charge as the magnitude. Thus, even in cases when the charge is negative, it turns positive due to the mod. Thus, Electric Field similarly changes to a positive state. Consequently, the electric field is always positive. The experiment is related to the orientation of the electric field line from the positive end to the negative.

A non-conservative force is a force acting on an object and the work done by the force on the object depends on the distance traveled. During the motion of a body due to non-conservative forces, mechanical energy is dissipated, so non-conservative forces can be called dissipative gradients. In most cases, lost energy cannot be recovered. Friction is a good example of a non-conservative force.

Position is measured in meters (m). Velocity is measured in meters per second (m/s). Acceleration is measured in meters per second squared (m/s^2).

Velocity:

Velocity is the directional velocity of a moving object as an indicator of the rate of change of position, observed from a certain frame of reference and measured at a certain time reference (eg 60 km/h northward). Velocity is a fundamental concept in kinematics, a branch of classical mechanics that describes the motion of bodies.

Acceleration:

Acceleration is the rate of change of an object's velocity with respect to time. Acceleration is a vector quantity (as long as it has magnitude and direction).

At the highest point, the speed is zero which is v = 0 and the acceleration is due to gravity which is in the opposite direction of the movement of the ball. Thus,
