When two charged plates are separated by a distance, the potential difference between the plates is 54 Volts.

The electric field intensity which does not increase or decrease with time or remain constant is called the uniform electric field.

Given is the plates separated by distance d = 15 cm =0.15 m, electric field E= 360 N/C.

The relation between the electric field and voltage is

E=V/d

Substitute the values into the expression to get the potential difference V,

V = 360 x 0.15

V = 54 Volts

Thus, the potential difference between the plates is 54 Volts.

The time taken by the train will be 13.84 sec. Time taken is the ratio of the distance and speed.

Distance is a numerical representation of the distance between two objects or locations.

Distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.

Distance is found as the product of the speed and velocity.

Distance = speed × time

time = Distance/speed

time= 1275 (m)/92.1( m/sec)

time(t) =13.84 sec

Hence, the time taken by the train will be 13.84 sec

Student 2 is correct. The Benz is not traveling at constant velocity. At the end of two seconds the speed would have increased by 4.4 m/s.

The final velocity of the benz is determined by using first kinematic equation;

v = u + at

where;

v = 2.2 + (2.2 x 2)

v = 6.6 m/s

Δv = 6.6 m/s - 2.2 m/s = 4.4 m/s

Thus, student 2 is correct. The Benz is not traveling at constant velocity. At the end of two seconds the speed would have increased by 4.4 m/s.

The depth of the crack along the aeroplane wing is determined as 1.5 m.

The depth of the crack in the wing from which the echo is heard is calculated as follows;

d = (vt)/2

From the image;

d1 = (5000 x 0.4 x 10⁻³)/2

d1 = 1 m

d2 = (5000 x 0.8 x 10⁻³)/(2)

d2 = 2 m

Average depth

d = (d1 + d2)/2

d = (1 + 2)/2

d = 1.5 m

Thus, the depth of the crack along the aeroplane wing is determined as 1.5 m.

When you are riding in a coaster car that is traveling at a constant speed, you only feel the downward force of gravity. But as the car speeds up or slows down, you feel pressed against your seat or the restraining bar. You feel this force because your inertia is separate from that of the coaster car.

1 Conditions that result in the emission of electrons from a conductor:

Heating the conductor to a suitable temperature

Exposing the conductor to a strong light

Subjecting the conductor to a very high applied voltage

Subjecting the conductor to high-speed electrons from another source

2 Both diodes and triodes influence current flow and contain electrodes. Diodes involve only two active pieces; triodes contain three electrodes within a tube. Current can flow through a diode in only one direction. Diodes tend to act as rectifiers. In a triode, the third electrode is a grid located between the cathode and the anode. A small difference of potential between the grid and the cathode controls the number of electrons that reach the anode. Adjusting the charge on the grid affects the number of electrons that can reach the anode. Triodes tend to act as amplifiers.

There are four main ways in which electrons are emitted from the conductor including Thermionic emission, Electric field electron emission,  Photoelectric emission, and Secondary emission.

A conductor is a substance or material which allows electricity to flow through it. In a conductor, the electrical charge carriers, usually electrons or ions or charged particles, move easily from one atom to another atom when the voltage is applied.

Thermionic emission involves large amount of external energy in the form of heat is supplied to release free electrons from the metal.

In the electric field electron emission, electrons are emitted from the metal surface when the metals are placed in a very strong electric field.

During photoelectric emission, light is absorbed by the metals and this provides energy to the valence electrons in the conductor which break their bond with the parent atom and which are then released from the atom.

Valence electrons have kinetic energy, however they don't have enough energy to escape from the atom. During secondary emission, a high-speed electron from the conductor is bombarded with an atom, which provides energy for the valence electrons to break their bonds with their parent atom which are then released from the atom.

Answer:

The impulse experienced by the object equals the change in momentum of the object. In equation form, F • t = m • Δ v. In a collision, objects experience an impulse; the impulse causes and is equal to the change in momentum.

Explanation:

When A 0.025 kg piece of clay is thrown into a wall and has a speed of 9 m/s before it strikes the wall then change in momentum 22.5 kg.m/s² is and impulse is 0.225 Ns.

Momentum is defined as product of mass and velocity of the body. It is denoted by letter p and it is expressed in kg.m/s.

Mathematically p = mv.

it discuss the moment of the body. body having zero mass or velocity has zero momentum.

The dimensions of the momentum is [M¹ L¹ T⁻¹].

Given,

mass of the clay = 0.025 Kg

Speed of the clay = 9m/s

The momentum of clay is P = mv = 0.025×9 =0.225 kg.m/s

In this problem a piece of clay having mass 0.025 Kg, velocity of clay is 9m/s.

By using formula,

change in momentum of the clay = dp/dt

We must know about change in time in order to calculate change in momentum with respect to time.

Consider that the change in momentum is 0.01s.

dp/dt = p₂-p₁/t₂-t₁ = 0- 0.225/0.01 = 22.5 kg.m/s²

Impulse = dp/dt×Δt = 22.5×0.01 = 0.225 Ns

The motorcycle's average velocity will be 20 m/sec. The ratio of the overall distance traveled to the total time taken by the body is the average velocity.

The average velocity is the ratio of the total distance traveled to the total time taken by the body. Its unit is m/sec.

V= 72km/hr =20 m/sec

Total distance travelled by the  motorcycle;

D= v ×t

D=(20 m/sec)×20 sec

D=400 m

The average velocity is:

[tex]\rm v_{avg}=\frac{d_{total}}{t_{total}} \\\\ \rm v_{avg}=\frac{400}{20} \\\\ v_{avg}=20 m/sec[/tex]

Hence,the motorcycle’s average velocity will be 20 m/sec.

The thin atmosphere of Mars is thought to be due to the planet's lack of a magnetic field, which has allowed the Solar wind to blow away much of the gas the planet once had. Venus, despite still having a thick atmosphere of CO2, surprisingly has a similar problem

The electrostatic force between these electrons will be 2.3×10⁻²⁰ N.

The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Charges that are similar repel each other, whereas charges that are diametrically opposed attract each other.

They will repel, moving in opposite directions at the same speed. Because the magnitude and nature of the charge are same.

The electrostatic force between these electrons is;

[tex]\rm F= \frac{Kq_1q_2}{r^2} \\\\ F=\frac{9 \times 10^9 \times -1.6 \times 10^{-19} \times- 1.6 \times 10^{-19} }{(0.10 \times 10^-3)^2} \\\\F= 2.3 \times 10^{-20} \ N[/tex]
