The investigation provides a useful method for determining the composition of a wedding ring, but caution should be taken in interpreting the results due to potential sources of error.

a) To investigate whether the wedding ring is made of pure gold or a mixture of gold and silver, we can use the density of the ring as a clue. Firstly, we need to weigh the ring using a scale with high precision. Then, we can calculate the volume of the ring by measuring its dimensions and using the formula for the volume of a cylinder (V=πr²h). Once we have the weight and volume of the ring, we can calculate its density by dividing the weight by the volume. If the density of the ring is close to the density of pure gold (19.3g/cm³), then the ring is likely to be made of pure gold. However, if the density of the ring is lower than that of pure gold, it may indicate that the ring is made of a mixture of gold and silver.

b) The most significant source of error in our investigation is that the ring may contain other metals or impurities that affect its density. Additionally, the precision of the scale and measurements of the ring's dimensions can also affect the accuracy of our calculations. Therefore, we need to use high-precision instruments and repeat our measurements several times to ensure the accuracy of our results.

The EMF of a cell represents its maximum potential difference, while the potential difference across the cell when passing a current through an external resistance is reduced due to the internal resistance of the cell.

The electromotive force (EMF) of a cell refers to the maximum potential difference that the cell can provide when it is not connected to any external circuit. It is essentially the voltage produced by the chemical reactions occurring within the cell. On the other hand, the potential difference across the cell when it is passing a current through an external resistance is often lower than the EMF.

This difference in values can be attributed to the internal resistance of the cell. When a current is drawn from the cell, it encounters resistance within the cell itself due to factors such as the resistance of the electrolyte and the internal structure of the cell. This internal resistance causes a voltage drop within the cell, reducing the potential difference across the external circuit.

According to Ohm's Law (V = I * R), when current flows through a resistance (R), a voltage drop (V) occurs. In this case, the internal resistance of the cell causes a voltage drop within the cell itself. Hence, the potential difference across the external resistance is slightly lower than the EMF of the cell.

The torque, often denoted as τ, can be calculated by multiplying the force (in newtons, N) applied at 90 degrees to the lever arm (in meters, m) from the pivot point (point of rotation). The compound SI unit for torque is newton-meter (N⋅m).

Torque is a measure of the rotational force or moment that tends to cause an object to rotate around an axis or pivot point. It depends not only on the magnitude of the force but also on the distance between the force application point and the pivot point.

In the context of a lever, the torque can be calculated as τ = F * r * sin(θ), where F is the force applied perpendicular to the lever arm, r is the distance from the pivot point to the force application point, and θ is the angle between the force vector and the lever arm.

Understanding and calculating torque is crucial in various fields, such as physics, engineering, and mechanics, as it helps determine the rotational behavior and equilibrium of objects subjected to forces.

The radius of the cylinder is approximately 2.19 m, and the cylinder is experiencing a deceleration of approximately 1.86 m/s². Since the cylinder is decelerating and the force applied is less than the friction force, it is not slipping.

From the given information:

Mass of the cylinder, m = 5 kg

Moment of inertia of the cylinder, I = 12 kg·m²

Diameter of the cylinder, D = 0.5 m

Force applied, F = 25 N

Coefficient of friction, μ = 0.7

Radius of the cylinder, r = ?

To determine the radius (r) of the cylinder, we can use the relationship between moment of inertia (I) and mass (m) for a solid cylinder:

I = (1/2) * m * r²

Given I = 12 kg·m² and m = 5 kg, we can solve for r:

12 = (1/2) * 5 * r²

r² = 12 / (1/2) * 5

r² = 12 / 2.5

r² = 4.8

r ≈ √4.8

r ≈ 2.19 m

So, the radius of the cylinder is approximately 2.19 m.

Now, let's determine the acceleration of the cylinder. The force applied is given as F = 25 N. The friction force can be calculated using the equation:

Friction force = μ * Normal force

Since the cylinder is being pulled by the string, the normal force is equal to the weight of the cylinder, which is given by:

Weight = mass * acceleration due to gravity

Weight = m * g

Assuming a standard acceleration due to gravity of 9.8 m/s²:

Weight = 5 kg * 9.8 m/s² = 49 N

Friction force = μ * Normal force = μ * Weight = 0.7 * 49 N = 34.3 N

Now, we can calculate the net force acting on the cylinder:

Net force = Force applied - Friction force

Net force = 25 N - 34.3 N

Net force = -9.3 N

Since the net force is negative, indicating that the force applied is less than the friction force, the cylinder will experience a deceleration rather than acceleration. The magnitude of the deceleration can be calculated using Newton's second law:

Net force = mass * acceleration

-9.3 N = 5 kg * acceleration

acceleration = -9.3 N / 5 kg

acceleration = -1.86 m/s²

The negative sign indicates that the deceleration is in the opposite direction to the force applied, which means the cylinder is moving in the direction opposite to the applied force.

Hence, the radius of the cylinder is approximately 2.19 m, and the cylinder is experiencing a deceleration of approximately 1.86 m/s². Since the cylinder is decelerating and the force applied is less than the friction force, it is not slipping.

v = ?

As we know,

⇒  \(K.E=\frac{1}{2} (mass\times speed^2)\)

On substituting the values, we get

⇒  \(90=\frac{1}{2} (30\times v^2)\)

⇒  \(90=15\times v^2\)

⇒  \(v^2=\frac{90}{15}\)

⇒  \(v^2=6\)

⇒  \(v=\sqrt{6}\)

⇒  \(v=2.44 \ m/s\)

A change in speed leads to an acceleration. When an object is rotating and its velocity is changing, we say it is accelerating angularly. Angular acceleration is also called rotational acceleration. It quantitatively expresses the change in angular velocity per unit time. Angular acceleration is a pseudo scalar. The sign of angular acceleration is considered positive if the angular velocity increases counterclockwise and negative if the angular velocity increases clockwise. Angular acceleration is used to study the motion of rotating objects such as wheels, fans, and the earth.

For the given problem:

α = 2θ/t²

Where, α = angular acceleration

θ = angle of rotation (25 rad)

t = time (5 sec)

α = 2×25/5²

α = 50/25

α = 2 rad/s²

ω = Δθ/Δt

Where, ω = average angular velocity

θ = angle of rotation (25 rad)

t = time (5 sec)

ω = 25/5

ω = 5 rad/s

ωₓ = α × t

Where, ωₓ = instantaneous angular velocity

α = angular acceleration (2 rad/s²)

t = time (5 sec)

ωₓ = 2 × 5

ωₓ = 10 rad/s

θ = ω₀t + ¹/₂αt²

Where, θ = angle of rotation

ω₀ = initial angular velocity (0 rad/s)

t = time (10 sec)

α = angular acceleration (2 rad/s²)

Since, ω₀ = 0

θ = ¹/₂αt²

θ = ¹/₂ × 2 × 10²

The angular velocity of the moon is approximately \(2.7 \times 10^{-6\) rad/s, which is the answer (d).

To calculate the angular velocity of the moon, we first need to understand what angular velocity is. Angular velocity is defined as the rate of change of angular displacement with respect to time. In simpler terms, it is the speed at which an object is rotating or moving in a circular path.

In this case, the moon is moving in a circular path around the Earth, so we can use the formula for angular velocity:

ω = θ / t

where ω is the angular velocity, θ is the angular displacement, and t is the time taken for one complete revolution.

We know that the time taken for one complete revolution of the moon around the Earth is 27.3 days. To convert this into seconds, we multiply by 24 hours in a day, 60 minutes in an hour, and 60 seconds in a minute:

t = 27.3 x 24 x 60 x 60 = 2,360,320 seconds

Now we need to find the angular displacement of the moon in one complete revolution. Since the moon moves in a circular path, its angular displacement is equal to the angle subtended by its path at the center of the earth. This angle is equal to 2π radians since the circumference of a circle is 2π times its radius (in this case, the distance from the moon to the center of the earth).

θ = 2π radians

Now we can substitute these values into the formula for angular velocity:

\(\omega = \frac{\theta}{t} = \frac{2\pi}{2{,}360{,}320} \approx 2.7\times 10^{-6}\ \mathrm{rad/s}\)
