The things that get in the way of electrical flow is called insulator.

An insulator is a material (body or substance) that resists electrical flow through it. Therefore, it can be said that the insulator gets in the way of electricity flow. Electrical insulators usually have electrons that are tightly bounded to each other, making them not able to move freely.

Electrical insulators are usually used to support and separate electrical conductors in various electrical equipment. The purpose is to hold the conductors in position without allowing electrical current through itself.

The maximum height that the ball reaches is 8.79 m and  the range of the ball is  12.29 m

To find the maximum height that the ball reaches, you will need to use the equation for the vertical displacement (y) of the ball:

y = Vy * t - (1/2) * g * t^2

Where Vy is the vertical component of the initial velocity, t is the time elapsed, and g is the acceleration due to gravity.

To find the time at which the ball reaches its maximum height, set the vertical displacement (y) to zero and solve for t:

0 = Vy * t - (1/2) * g * t^2

This equation can be rearranged to:

t = √(2Vy/g)

Then, substitute the given values for the initial velocity (Vy) and the acceleration due to gravity (g), and solve for t:

t = √(2 * 15 m/s * sin(50) / 9.8 m/s^2)

t = 1.16 s

y = Vy * t - (1/2) * g * t^2

y = 15 m/s * sin(50) * 1.16 s - (1/2) * 9.8 m/s^2 * (1.16 s)^2

y = 8.79 m

To find the range of the ball, you will need to use the equation for the horizontal displacement (x) of the ball:

x = Vx * t

Where Vx is the horizontal component of the initial velocity and t is the time elapsed.

To find the time elapsed (t), use the equation for the time at which the ball reaches its maximum height:

t = √(2Vy/g)

Substitute the given values for the initial velocity (Vy) and the acceleration due to gravity (g), and solve for t:

t = √(2 * 15 m/s * sin(50) / 9.8 m/s^2)

t = 1.16 s

To find the horizontal component of the initial velocity (Vx), use the equation:

Vx = V0 * cos(θ)

Where V0 is the initial velocity of the ball and theta is the angle of launch. Substitute the given values for the initial velocity (V0) and the angle of launch (theta), and solve for Vx:

Vx = 15 m/s * cos(50)

Vx = 10.6 m/s

To find the range of the ball, substitute the values for the horizontal component of the initial velocity (Vx) and the time elapsed (t) into the equation for the horizontal displacement (x):

x = Vx * t

x = 10.6 m/s * 1.16 s

The disk will continue to spin if the ring strikes it off-center, but the moment of inertia will be affected.

The disk will be out of balance due to the ring's off-center placement, which will result in a lower moment of inertia than it would have if the ring were centered. The disk will therefore not spin as quickly or for as long as it would if the ring were in the middle.

This implies that the ring's rotational energy will not be dispersed uniformly, leading to an uneven, or skewed, rotation. The off-center ring's inability to accurately reflect the moment of inertia will result in an erroneous measurement of it.

There is an air dielectric breakdown (10 mT). This happens when air (a dielectric) breaks down and charges are transferred from the sky to the earth.

In an electromagnetic wave, the connection between the strength of the electric and magnetic fields is E=cB.

The speed of light is c.

B is the magnetic field's strength.

E=3.106V/m is the electric field, and c=3.108m/s is the speed of light in this equation.

When we solve for B, we get B=E/c=3.106 V/m/3.108 m/s=0.01T=10mT.

When the electrical voltage across a material is greater than the substance's dielectric strength, dielectric breakdown occurs, leading to partial ionization. When a gas breakdowns, the ionization dramatically diminishes the gas' electrical insulating qualities, producing a spark or an arc.

A transmission Grid is called a network of transformers and transmission cables that transfer electrical power from power stations to consumers

Electrical transmission is the process of providing highly efficiently generated electricity to a district or over larger and longer distances. The main point of the grid is to give people access to electricity 24 hours without interruption and without any trouble in populated areas. Transformers play a crucial role in this. Transformer help in increasing the voltage of the grid to make it more powerful and effective. It helps in the feasible transmission of the grid.

The electrical transmission system is combined with power plants in cities, distribution systems for easier access to electricity, and sub-stations for backup and other purposes which is to form what is known as the electrical grid.

Condensed water droplets collect other water droplets to form the collector drop until they fall from the clouds as rain. In this way rain is formed in the tropics where the air is warmer.

A significant volume of water evaporates and is released into the atmosphere when water bodies are heated during the day. Evaporation is the term for this. Water vapour is carried upward by the hot air as it rises. The air cools and expands as it rises. Condensation is the term for this occurrence. Clouds are created as a result of water vapour condensation. With the assistance of the wind, these clouds are transported away, and when they become heavy, they drop to the ground as rain.

(a) The highest possible rate of kinetic energy is -2.2 eV and the highest possible rate of speed is 2.3 × 10⁶ m/s.

(b) The length of the radiation's wave is 86 nm.

(c) The lowest frequency of visible light is 3.5 x 10¹⁴ Hz.

To solve this problem, we can use the following equations:

- The maximum kinetic energy of the electrons emitted from the sodium surface is given by:

KEmax = Work function - Potential difference

- The maximum speed of the electrons is given by:

vmax = sqrt (2 × KEmax ÷ m)

where m is the mass of the electron.

- The incident radiation wavelength can be calculated using the Planck-Einstein equation:

E = h × f

where E is the energy of the incident radiation, h is the Planck constant, and f is the frequency of the radiation.

- The minimum frequency required for photoemission can be calculated using the work function of the sodium surface:

fmin = Work function ÷ h

- Using these equations, we can calculate the following:

(a) The maximum kinetic energy of the electrons is given by:

KEmax = 2.3 eV - 4.5 V = -2.2 eV

Hence,  the maximum kinetic energy is -2.2 eV.

- The maximum speed of the electrons is given by:

vmax = sqrt(2 × (-2.2 eV) ÷ (9.1 × 10⁻³¹ kg)) = 2.3 × 10⁶ m/s

Hence the maximum speed is 2.3 × 10⁶ m/s.

(b) The incident radiation wavelength can be calculated using the Planck-Einstein equation:

E = h × f

f = E ÷ h

f = 2.3 eV / (6.6 × 10⁻³⁴ J × s) = 3.5 × 10¹⁴ Hz

lambda = c ÷ f

lambda = (3.0 x 10⁸ m/s) ÷ (3.5 x 10¹⁴ Hz) = 8.6 x 10⁻⁷ m = 86 nm.

Hence, the wavelength of the radiation is 86 nm.

(c) The minimum frequency required for photoemission can be calculated using the work function of the sodium surface:

fmin = 2.3 eV ÷ (6.6 × 10⁻³⁴ J × s) = 3.5 × 10¹⁴ Hz

Hence, the minimum frequency of light is 3.5 × 10¹⁴ Hz.
