The force experienced by the electron is given by:

F = Eq

where E is the electric field strength and q is the charge of the electron.

The charge of the electron is -1.6 × 10^-19 C.

Substituting the values, we get:

3.0 × 10^-6 N = E(-1.6 × 10^-19 C)

Solving for E, we get:

E = (3.0 × 10^-6 N) / (-1.6 × 10^-19 C)

E = -1.875 × 10^13 N/C

The magnitude of the electric field strength between the deflection plates is 1.875 × 10^13 N/C.

Therefore, the electric field (magnitude only) at a distance of 8.0 cm from the wire is approximately 3.24 x 10^4 N/C.

The electric field of a long, thin wire can be determined by Coulomb's law. Coulomb's Law states that the electric force between two charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

For a long, thin wire, the electric field is given by;

E = λ/2πε₀r

Where;

λ = linear charge density = 91 µC/m,

ε₀ = permittivity of free space = 8.85 x 10^-12 C^2/Nm^2

r = distance from the wire = 8.0 cm = 0.08 m.

Substitute the given values into the formula to find the electric field;

E = (91 x 10^-6)/(2 x π x 8.85 x 10^-12 x 0.08)

E≈ 32433.8 N/C

E≈ 3.24 x 10^4 N/C.

Electric field refers to the force per unit charge that one object exerts on another object due to the electric charge present in the objects. It is a vector quantity and is measured in newtons per coulomb (N/C).

A photon's energy does not increase four times when its momentum doubles because a photon's kinetic energy is inversely correlated with its frequency.

A photon is a quantum of the electromagnetic field and an elementary particle. It is also referred to as light particle or electromagnetic wave. As a result of its dual nature, the photon behaves as both a particle and a wave. It travels at the speed of light, and it has momentum and energy. Photons are the basic units of light and other types of electromagnetic radiation.The momentum of a photon is given by p = hf/c, where h is Planck's constant, the photon's frequency is f, and the speed of light is c.

As a result, a photon's frequency and wavelength also double when its momentum does. Nevertheless, rather than its momentum, its kinetic energy is related to its frequency. Hence, a photon's energy increases by two, not four, times, when its momentum doubles. E = hf, where h is Planck's constant and f is the photon's frequency, calculates the energy of a photon.

Hence, instead of doubling in size when the photon's frequency doubles, its energy increases by a factor of four instead.

Since the momentum remains same before and after push-off, therefore Tracey's speed will be 0.492 m/s.

Momentum is a product of mass and the velocity of a body.

The initial momentum is always equal to the final momentum during collisions between two bodies.

Therefore; M₁U₁ +M₂U₂ = M₁V₁+ M₂V₂,

where M₁ is the mass of Tracey

M₂ is the mass of Jonas,

U is the initial velocity

V is the final velocity.

(32 ×0)+ (45×0) = (32 × V₁) + (45 × 0.35)

0 = 32V₁ + 15.75

Acceleration is defined as the rate of change of velocity, so it is the change in velocity divided by the time taken.

To calculate the acceleration of the car from the speed time graph, we need to determine the change in speed over a specific time interval.
If the speed time graph shows a straight line, we can use the slope of the line to calculate the acceleration. The slope of a straight line is given by the change in y divided by the change in x. In this case, the change in y is the change in speed and the change in x is the change in time.
If the speed time graph shows a curve, we can use the tangent to the curve at a specific point to calculate the acceleration. The tangent represents the instantaneous velocity at that point, and the slope of the tangent gives the instantaneous acceleration.
Once we have calculated the acceleration, we can interpret it in terms of how quickly the car is changing its speed. If the acceleration is positive, the car is speeding up. If the acceleration is negative, the car is slowing down. The magnitude of the acceleration gives us an idea of how quickly the car is changing its speed.
In summary, to calculate the acceleration of a car from a speed time graph, we need to determine the change in speed over a specific time interval.

A measurement of an object's inertia is made via its mass.

Inertia is the property of an object that resists changes in its motion, and mass is a measure of the amount of matter in an object. The greater an object's mass, the greater its inertia, and the more force is required to change its motion. Therefore, the mass of an object is a crucial factor in determining its inertia.

Mass is a fundamental property of matter that measures the amount of matter in an object. It is a scalar quantity that is expressed in units of kilograms (kg) in the International System of Units (SI). The more massive an object is, the greater its inertia, meaning that it is more resistant to changes in its motion.

The inertia of an object is related to the amount of force required to accelerate it. Newton's second law of motion states that the force required to accelerate an object is directly proportional to its mass and the rate of acceleration. That is, F = ma, where F is the force applied, m is the mass of the object, and a is the acceleration of the object.
