The position of the mass as a function of time is x(t) = 5 * sin(4t).

To find the position of the mass as a function of time, we can use Newton's second law of motion, which states that the sum of the forces acting on an object is equal to the mass of the object multiplied by its acceleration.

The equation of motion for a mass-spring system is given by:

m * d^2x/dt^2 + k * x = F(t)

Where:

m is the mass connected to the spring,

x is the position of the mass,

t is time,

k is the spring constant,

F(t) is the applied force as a function of time.

In this case, the mass m is 2 kg, the spring constant k is 32 N/m, and the applied force is given by F(t) = 128sin(4t).

Plugging these values into the equation of motion, we get:

2 * d^2x/dt^2 + 32 * x = 128sin(4t)

Rearranging the equation, we have:

d^2x/dt^2 + 16 * x = 64sin(4t)

This is a second-order linear ordinary differential equation with constant coefficients. To solve this equation, we can assume a solution of the form x(t) = A * sin(ωt + φ), where A is the amplitude, ω is the angular frequency, and φ is the phase angle.

Differentiating x(t) twice with respect to time, we have:

dx/dt = A * ω * cos(ωt + φ)

d^2x/dt^2 = -A * ω^2 * sin(ωt + φ)

Substituting these derivatives into the equation of motion, we get:

-A * ω^2 * sin(ωt + φ) + 16 * A * sin(ωt + φ) = 64sin(4t)

Equating the terms with sin(ωt + φ) on both sides, we have:

-A * ω^2 + 16 * A = 64

Simplifying the equation, we get:

16A - Aω^2 = 64

We know that the angular frequency ω is related to the spring constant k and the mass m as ω = √(k/m). Substituting the given values, we have:

ω = √(32 N/m / 2 kg) = √(16) = 4

Plugging ω = 4 into the equation, we get:

16A - 16 = 64

Solving for A, we have:

16A = 80

A = 5

Therefore, the amplitude A is 5.

Now, we can write the position function as:

x(t) = 5 * sin(4t + φ)

To find the phase angle φ, we can use the initial conditions. At t = 0, the spring is initially at rest and hanging at its equilibrium position, which means x(0) = 0.

Plugging this into the position function, we have:

0 = 5 * sin(0 + φ)

Since sin(0) = 0, we get:

0 = 0 + φ

φ = 0

Therefore, the phase angle φ is 0.

Finally, the position of the mass as a function of time is:

x(t) = 5 * sin(4t)

The speed of Vc at the instant bead collide is 1.38 m/s and the instant speed of Vd at the instant bead collide is 0.106 m/s.

The force of attraction on the beads are due to both gravitational force and electrostatic force

As gravitational force is very weak force as compared to electrostatic force the net force will be due to electrostatic force only.

Net Force = Electrostatic force

Net Force = K q1 q2 / r²

Net Force = (9 × 10⁹) (2.5 × 10⁻⁹) (1 × 10⁻⁹) / (14 × 10⁻³) (as distance between there centre of mass is 14 mm)

Net Force = (9 × 2.5 × 10⁻⁶) / 14

Net Force = 1.6 × 10⁻⁶

For bead c

Force = Mc × Ac = 1.6 × 10⁻⁶

(1 × 10⁻³) × Ac = 1.6 × 10⁻⁶

Ac = 1.6 × 10⁻³

Acceleration of bead C is 1.6 × 10⁻³ m/s²

For bead d

Force = Md × Ad = 1.6 × 10⁻⁶

(1.7 × 10⁻³) × Ad = 1.6 × 10⁻⁶

Ad = 0.94 × 10⁻³

Acceleration of bead D is 0.94 × 10⁻³ m/s²

Let us suppose bead C travels y distance before collision

So bead D should travel 12-y distance before collision

So speed of both the beads before the collision can be find out by using newton third law of motion

For bead C

Vc² - Uc² = 2 Ac s

Vc² = 2 × 1.6 × 10⁻³ × y

Vc² = 3.2 × 10⁻³ × y

Vc = √(3.2 × 10⁻³ × y)

For bead D

Vd² - Ud² = 2 Ad s

Vd² = 2 × 0.94 × 10⁻³ × (12-y)

Vd² = 1.88 × 10⁻³ × (12-y)

Vd = √(1.88 × 10⁻³ × (12-y))

Applying energy conservation

initial = final

0 + 0 = (1/2)McVc² - (1/2)MdVd²

(1/2)McVc² = (1/2)MdVd²

McVc² = MdVd²

1 × 10⁻³ × 3.2 × 10⁻³ × y = 1.7 × 10⁻³ × 1.88 × 10⁻³ × (12-y)

3.2 × y = 3.2 × (12-y)

y = 12-y

2y = 12

y = 6

Putting the value of y in Vc and Vd

Vc = √(3.2 × 10⁻³ × y)

Vc = √(3.2 × 10⁻³ × 6)

Vc = √(19.2 × 10⁻³)

Vc = √0.0192

Vc = 1.38 m/s   (approximately)

Vd = √(1.88 × 10⁻³ × (12-y))

Vd = √(1.88 × 10⁻³ × (12-6))

Vd = √(1.88 × 10⁻³ × 6)

Vd = √(11.28 × 10⁻³)

Vd = √0.01128

Vd = 0.106 m/s   (approximately)

So the speed of Vc at the instant beads collide will be approximately 1.38 m/s and Vd at the instant speed the beads collide will be approximately 0.106 m/s.

Electron shielding reduces the effective nuclear charge.

Electron shielding refers to the phenomenon where inner electron shells in an atom partially block the attractive force of the positively charged nucleus on the outer electrons. This shielding effect arises from the repulsion between negatively charged electrons. As a result, the outer electrons experience a reduced effective nuclear charge, which is the positive charge felt by an electron due to the nucleus.

The shielding effect can be explained by considering the electron distribution in an atom. Inner electrons occupy regions closer to the nucleus, creating a barrier that diminishes the electrostatic attraction between the outer electrons and the nucleus.

(i)Therefore, it takes approximately 9.27 hours to reach its full power output.(ii)It is necessary to have quick-start power sources, this helps maintain a stable and reliable electricity supply even when wind speeds fluctuate.(c)The Bremsstrahlung effect needs to be considered to ensure proper radiation protection.(d) The near-field region is characterized by strong electric and magnetic fields while the far-field region represents the radiation zone.

(i) To calculate the time it takes for the power station to reach its full power output, we can use the formula:

Energy = Power × Time

Given that the power station generates 6120 MWh of energy over a 10-hour period and the rated power at full capacity is 660 MW, we can rearrange the formula to solve for time:

Time = Energy ÷ Power

Converting the energy to watt-hours (Wh):

Energy = 6120 MWh × 1,000,000 Wh/MWh = 6,120,000,000 Wh

Converting the power to watt-hours (Wh):

Power = 660 MW × 1,000,000 Wh/MW = 660,000,000 Wh

Now we can calculate the time:

Time = 6,120,000,000 Wh ÷ 660,000,000 Wh ≈ 9.27 hours

Therefore, it takes approximately 9.27 hours (or 9 hours and 16 minutes) for the power station to reach its full power output.

(ii) The type of power station that can be started up fastest is a gas-fired power station. Gas-fired power stations can reach full power output relatively quickly because they use natural gas combustion to produce energy.

In contrast, other types of power stations, such as coal-fired or nuclear power stations, have longer start-up times. Coal-fired power stations require time to heat up the boiler and generate steam, while nuclear power stations need to go through a complex series of procedures to ensure safe and controlled nuclear reactions.

This is relevant to optimizing the usage of windfarms because wind power is intermittent and dependent on the availability of wind. This helps maintain a stable and reliable electricity supply even when wind speeds fluctuate.

(c) The Bremsstrahlung effect is a phenomenon that occurs when charged particles, such as electrons, are decelerated or deflected by the electric fields of atomic nuclei or other charged particles. As a result, they emit electromagnetic radiation in the form of X-rays or gamma rays.

In shielding design, the Bremsstrahlung effect needs to be considered to ensure proper radiation protection. These materials effectively absorb and attenuate the emitted X-rays and gamma rays, reducing the exposure of individuals to harmful radiation.

(d) The electromagnetic field output from an antenna can be represented by two main regions:

Near-field region: This region is closest to the antenna and is also known as the reactive near-field. It extends from the antenna's surface up to a distance typically equal to one wavelength. In the near-field region, the electromagnetic field is characterized by strong electric and magnetic field components.

Far-field region: Also known as the radiating or the Fraunhofer region, this region extends beyond the near-field region.The electric and magnetic fields are perpendicular to each other and to the direction of propagation.  The far-field region is further divided into the "Fresnel region," which is closer to the antenna and has some characteristics of the near field, and the "Fraunhofer region," which is farther away and exhibits the properties of the far-field.

The transition between the near-field and the far-field regions is gradual and depends on the antenna's size and operating frequency. The size of the antenna and the distance from it determine the boundary between these regions.

In summary, the near-field region is characterized by strong electric and magnetic fields, while the far-field region represents the radiation zone where the energy is radiated away as electromagnetic waves.

When a pulse traveling along a light spring reaches the boundary with a heavier spring, some of the pulse energy will be reflected back into the light spring, and some will be transmitted into the heavier spring. The amount of energy reflected and transmitted depends on the properties of the two springs and the angle of incidence of the pulse.

In general, if the two springs have different spring constants, the pulse will experience a change in velocity and amplitude at the boundary. The pulse will slow down when it enters the heavier spring, because the heavier spring will offer more resistance to deformation than the lighter spring. As a result, the wavelength of the pulse will decrease, and its amplitude will increase.

Whether the pulse is inverted or not at the boundary depends on the relative phase of the reflected and transmitted waves. If the boundary conditions are such that the reflected wave is in phase with the incident wave, the pulse will be inverted. If the reflected wave is out of phase with the incident wave, the pulse will not be inverted.

The exact behavior of the pulse at the boundary between the two springs depends on the specific properties of the springs, such as their spring constants and densities.

However, in general, the pulse will undergo a change in velocity, wavelength, and amplitude at the boundary, and may or may not be inverted depending on the relative phase of the reflected and transmitted waves.
