To calculate the gravitational force on the satellite while in orbit, we can use Newton's law of universal gravitation. The formula is as follows:

F = (G * m1 * m2) / r^2

Where:

F is the gravitational force

G is the gravitational constant (approximately 6.67430 × 10^-11 N m^2 / kg^2)

m1 and m2 are the masses of the two objects (in this case, the satellite and Earth)

r is the distance between the centers of the two objects (the radius of the orbit)

In this scenario, the satellite is in a circular orbit around the Earth, so the gravitational force provides the necessary centripetal force to keep the satellite in its orbit. Therefore, the gravitational force is equal to the centripetal force.

The centripetal force can be calculated using the formula:

Fc = (m * v^2) / r

Where:

Fc is the centripetal force

m is the mass of the satellite

v is the velocity of the satellite in the orbit

r is the radius of the orbit

Since the satellite is in a stable circular orbit, the centripetal force is provided by the gravitational force. Therefore, we can equate the two equations:

(G * m1 * m2) / r^2 = (m * v^2) / r

We can solve this equation for the gravitational force F:

F = (G * m1 * m2) / r

Now let's plug in the values given in the problem:

m1 = mass of the satellite = 648.9 kg

m2 = mass of the Earth = 5.972 × 10^24 kg (approximate)

r = radius of the orbit = 7RE = 7 * 6.400 x 10^6 m

Calculating:

F = (6.67430 × 10^-11 N m^2 / kg^2 * 648.9 kg * 5.972 × 10^24 kg) / (7 * 6.400 x 10^6 m)^2

F ≈ 2.686 × 10^9 N

Therefore, the gravitational force on the satellite while in orbit is approximately 2.686 × 10^9 Newtons.

Kinetic Energy this is correct answer.

For a situation when mechanical energy is conserved, when an object loses potential energy, that energy is converted into kinetic energy. According to the principle of conservation of mechanical energy, the total mechanical energy (the sum of potential energy and kinetic energy) remains constant in the absence of external forces such as friction or air resistance.

When an object loses potential energy, it gains an equal amount of kinetic energy. The potential energy is transformed into the energy of motion, causing the object to increase its speed or velocity. This conversion allows for the conservation of mechanical energy, where the total energy of the system remains the same.

The magnetic field B is approximately -1.32 x 10^-3 Tesla in the ar direction.

To calculate the magnetic field B, we can use the formula for the magnetic force experienced by a charged particle:

F = qvB

where F is the magnetic force, q is the charge of the particle, v is its velocity, and B is the magnetic field.

In this case, the force experienced by the electron is given as F = (421 ar + 8°) N.

We know that the charge of an electron is q = -1.6 x 10^-19 C (negative because it's an electron).

The velocity of the electron is given as v = (40.0 km/s)i + (33.0 km/s)j = (40.0 x 10^3 m/s)i + (33.0 x 10^3 m/s)j.

Comparing the components of the force equation, we have:

421 = qvB  (in the ar direction)

0 = qvB     (in the θ direction)

For the ar component:

421 = (-1.6 x 10^-19 C)(40.0 x 10^3 m/s)B

Solving for B:

B = 421 / [(-1.6 x 10^-19 C)(40.0 x 10^3 m/s)]

Similarly, for the θ component:

0 = (-1.6 x 10^-19 C)(33.0 x 10^3 m/s)B

However, since the θ component is zero, we don't need to solve for B in this direction.

Calculating B for the ar component:

B = 421 / [(-1.6 x 10^-19 C)(40.0 x 10^3 m/s)]

B ≈ -1.32 x 10^-3 T

So, the magnetic field B is approximately -1.32 x 10^-3 Tesla in the ar direction.

(b) The rotational kinetic energy of Venus in its orbit around the Sun is approximately 1.13 × 10^33 joules.

To calculate the rotational kinetic energy of Venus on its axis, we need to use the formula:

Rotational Kinetic Energy (K_rot) = (1/2) * I * ω^2

where:

I is the moment of inertia of Venus

ω is the angular velocity of Venus

The moment of inertia of a uniform solid sphere is given by the formula:

I = (2/5) * M * R^2

where:

M is the mass of Venus

R is the radius of Venus

(a) Rotational kinetic energy of Venus on its axis:

Given data:

Mass of Venus (M) = 4.87 * 10^24 kg

Radius of Venus (R) = 6.05 * 10^6 m

Angular velocity (ω) = (2π) / (time taken for one rotation)

Time taken for one rotation = 5.83 * 10^3 hours

Convert hours to seconds:

Time taken for one rotation = 5.83 * 10^3 hours * 3600 seconds/hour = 2.098 * 10^7 seconds

ω = (2π) / (2.098 * 10^7 seconds)

Calculating the moment of inertia:

I = (2/5) * M * R^2

Substituting the given values:

I = (2/5) * (4.87 * 10^24 kg) * (6.05 * 10^6 m)^2

Calculating the rotational kinetic energy:

K_rot = (1/2) * I * ω^2

Substituting the values of I and ω:

Approximately 3.867 ohms is the resistance of a 12m long wire of 12 gauge copper at room temperature.

To calculate the resistance of the copper wire, we can use the formula for resistance:

Resistance (R) = (ρ * length) / cross-sectional area

The resistivity of copper (ρ) at room temperature is 1.72 x 10^(-8) Ωm and the length of the wire (length) is 12 meters, we need to determine the cross-sectional area.

The gauge of the wire is given as 12 gauge, and the diameter (d) of a 12 gauge copper wire is 2.64 mm. To calculate the cross-sectional area, we can use the formula:

Cross-sectional area = π * (diameter/2)^2

Converting the diameter to meters, we have d = 2.64 x 10^(-3) m. By halving the diameter to obtain the radius (r), we find r = 1.32 x 10^(-3) m.

Now, we can calculate the cross-sectional area using the radius:

Cross-sectional area = π * (1.32 x 10^(-3))^2 ≈ 5.456 x 10^(-6) m^2

Finally, substituting the values into the resistance formula, we get:

Resistance (R) = (1.72 x 10^(-8) Ωm * 12 m) / (5.456 x 10^(-6) m^2)

≈ 3.867 Ω

Yes, there is a temperature at which the Kelvin and Celsius scales agree.  the temperature at which the Kelvin and Celsius scales agree is at -273.15°C, which corresponds to 0 Kelvin.

The Kelvin scale is an absolute temperature scale, where 0 Kelvin (0 K) represents absolute zero, the point at which all molecular motion ceases. On the other hand, the Celsius scale is based on the properties of water, with 0 degrees Celsius (0°C) representing the freezing point of water and 100 degrees Celsius representing the boiling point of water at standard atmospheric pressure.

To find the temperature at which the Kelvin and Celsius scales agree, we need to find the temperature at which the Celsius value is numerically equal to the Kelvin value. This occurs when the temperature on the Celsius scale is -273.15°C.

The relationship between the Kelvin (K) and Celsius (°C) scales can be expressed as:

K = °C + 273.15

At -273.15°C, the Celsius value is numerically equal to the Kelvin value:

-273.15°C = -273.15 + 273.15 = 0 K

Therefore, at a temperature of -273.15°C, which is known as absolute zero, the Kelvin and Celsius scales agree.

At temperatures below absolute zero, the Kelvin scale continues to decrease, while the Celsius scale remains positive. This is because the Kelvin scale represents the absolute measure of temperature, while the Celsius scale is based on the properties of water. As such, the Kelvin scale is used in scientific and technical applications where absolute temperature is important, while the Celsius scale is commonly used for everyday temperature measurements.

In summary, This temperature, known as absolute zero, represents the point of complete absence of molecular motion.

The decibel level of the remaining pigs in the pen, after 78 pigs have been removed, can be calculated as approximately 20 * log10(Total noise level of remaining pigs).

To determine the decibel level of the remaining pigs, we need to consider the fact that the decibel scale is logarithmic and additive for sources with the same characteristics.

Given that the noise level coming from a pig pen with 131 pigs is 60.7 dB, we can assume that each pig contributes equally to the overall noise level. Therefore, the noise level from each pig can be calculated as:

Noise level per pig = Total noise level / Number of pigs

= 60.7 dB / 131

Now, we need to consider the scenario where 78 pigs have been removed from the pen. Since each remaining pig squeals at their original level, the total noise level of the remaining pigs can be calculated as:

Total noise level of remaining pigs = Noise level per pig * Number of remaining pigs

= (60.7 dB / 131) * (131 - 78)

Simplifying the expression:

Total noise level of remaining pigs = (60.7 dB / 131) * 53

Finally, we have the total noise level of the remaining pigs. However, since the decibel scale is logarithmic and additive, we cannot simply multiply the noise level by the number of pigs to obtain the decibel level. Instead, we need to use the logarithmic property of the decibel scale.

The decibel level is calculated using the formula:

Decibel level = 10 * log10(power ratio)

Since the power ratio is proportional to the square of the sound pressure, we can express the formula as:

Decibel level = 20 * log10(sound pressure ratio)

Applying this formula to find the decibel level of the remaining pigs:

Decibel level of remaining pigs = 20 * log10(Total noise level of remaining pigs / Reference noise level)

The reference noise level is a standard value typically set at the threshold of human hearing, which is approximately 10^(-12) W/m^2. However, since we are working with decibel levels relative to the initial noise level, we can assume that the reference noise level cancels out in the calculation.

Hence, we can directly calculate the decibel level of the remaining pigs as:

Decibel level of remaining pigs = 20 * log10(Total noise level of remaining pigs)

Substituting the calculated value of the total noise level of the remaining pigs, we can evaluate the expression to find the decibel level.

The induced emf will be 9.0 V when the total enclosed area has tripled.

According to Faraday's law of electromagnetic induction, the induced emf (ε) in a circuit is proportional to the rate of change of magnetic flux through the circuit. The magnetic flux (Φ) is given by the product of the magnetic field (B) and the area (A) enclosed by the circuit.

In this scenario, the initially induced emf (ε1) is 3.0 V, and the initial area (A1) is known. When the total enclosed area becomes A2 = 3A1, it means the area has tripled. Since the speed of the rod is constant, the rate of change of area is also constant.

Therefore, the ratio of the final area (A2) to the initial area (A1) is equal to the ratio of the final induced emf (ε2) to the initial induced emf (ε1).

Mathematically, we can express this relationship as:

A2/A1 = ε2/ε1

Substituting the known values, A2 = 3A1 and ε1 = 3.0 V, we can solve for ε2:

3A1/A1 = ε2/3.0 V

3 = ε2/3.0 V

Cross-multiplying, we find:

a) To find the pressure in the bottle just before the cork is popped, we can use the ideal gas law, which states:

PV = nRT,

where P is the pressure, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature.

Since the volume of the bottle remains constant, we can write:

P₁/T₁ = P₂/T₂,

where P₁ and T₁ are the initial pressure and temperature, and P₂ and T₂ are the final pressure and temperature.

P₁ = 1 atm,

T₁ = 25°C = 298 K,

T₂ = 86°C = 359 K.

Substituting the values into the equation, we can solve for P₂:

(1 atm) / (298 K) = P₂ / (359 K).

P₂ = (1 atm) * (359 K) / (298 K) = 1.204 atm.

b) The magnitude of the friction force holding the cork in place can be determined by using the equation:

Given data, Velocity of proton, v = 4.9 × 10⁻¹⁰ m/s

Strength of magnetic field, B = 9.6 × 10⁻¹⁰ T

We know that the magnetic force is given by the equation:

F = qvBsinθ

where, q = charge of particle, v = velocity of particle, B = magnetic field strength, and θ = angle between the velocity and magnetic field vectors.

Now, the direction of the magnetic force can be determined using Fleming's left-hand rule. According to this rule, if we point the thumb of our left hand in the direction of the velocity vector, and the fingers in the direction of the magnetic field vector, then the direction in which the palm faces is the direction of the magnetic force.

Therefore, using Fleming's left-hand rule, the direction of the magnetic force is towards the west (perpendicular to the velocity and magnetic field vectors).

Now, substituting the given values, we have:

[tex]F = (1.6 * 10^{-19} C)(4.9 * 10^{-10} m/s)(9.6 *10^{-10} T)sin 90°F = 7.7 * 10^{-28} N[/tex]

Thus, the direction of the magnetic force is towards the west, and its strength is [tex]7.7 * 10^{-28}[/tex] N.

In this system, two particles of mass m are suspended by strings of length 1 from a common point. One particle has a charge of 2q, while the other has a charge of 3q. By analyzing the net torque on the system, it can be denoted as θ1 and θ2, are equal.

(a) In equilibrium, the net torque about the attachment point of the strings must be zero. The gravitational force acting on each particle can be decomposed into a component along the string and a component perpendicular to it.

Similarly, the electrostatic force acting on each particle can be decomposed into components parallel and perpendicular to the string. By considering the torques due to these forces, it can be shown that the net torque is proportional to sin(θ1) - sin(θ2).

Since the net torque must be zero, sin(θ1) = sin(θ2). As the angles are small, sin(θ1) ≈ θ1 and sin(θ2) ≈ θ2. Therefore, θ1 = θ2 = θ.

(b) When the angles are equal, the system reaches equilibrium. Drawing separate free-body diagrams for each particle, the forces along the x and y directions can be analyzed.

The sum of the forces in the x-direction is zero since the strings provide the necessary tension to balance the electrostatic forces. In the y-direction, the sum of the forces is equal to the weight of each particle. By using trigonometry, the tension in the string can be related to the angles and the weight of the particles.

(c) By analyzing the free-body diagrams, the sum of the forces in the x and y directions can be written. Using these equations and trigonometric relationships, an expression relating tan(θ) to the mass (m), string length (1), charge (q), and constants (g and E₀) can be derived.

(d) If θ is small, the expression from (a) can be approximated using small angle approximations. Applying this approximation and simplifying the expression, we find that θ ≈ (8.760mg/17)^(1/3).

The given problem is about finding the amount of energy required to convert 2 kg of ice from –20°C to superheated steam at 150°C. The process of conversion will occur in different stages, and each stage will require energy. The first step is to convert ice at –20°C to 0°C. The energy required for this stage is given as:

Q1 = mass x Lf x 0°C

Energy required = 2000 g x 333 J/g x 20°C = 13,320,000 J

(a) 0.952 m away from the image of the cyclist. (b) the image height of the cyclist is approximately 1.428 m. The image height can be determined using the magnification equation.

(a) The distance between you and the image of the cyclist can be determined using the mirror equation, which states that 1/f = 1/[tex]d_{i}[/tex] + 1/[tex]d_{o}[/tex], where f is the focal length of the mirror, [tex]d_{i}[/tex] is the distance of the image from the mirror, and [tex]d_{o}[/tex] is the distance of the object from the mirror. Given that the focal length of the mirror is -80 cm (negative due to it being a diverging mirror), and the distance between you and the mirror ([tex]d_{o}[/tex]) is 1.0 m, we can substitute these values into the equation to find the distance of the image ([tex]d_{i}[/tex]). Solving for [tex]d_{i}[/tex], we get 1/f - 1/[tex]d_{o}[/tex] = 1/[tex]d_{i}[/tex], or 1/-80 - 1/1 = 1/[tex]d_{i}[/tex]. Simplifying, we find that [tex]d_{i}[/tex] = -0.952 m. Therefore, you are approximately 0.952 m away from the image of the cyclist.

(b) The image height can be determined using the magnification equation, which states that magnification (m) = -[tex]d_{i}[/tex]/[tex]d_{o}[/tex], where [tex]d_{i}[/tex] is the distance of the image from the mirror and [tex]d_{o}[/tex] is the distance of the object from the mirror. Since we have already found [tex]d_{i}[/tex] to be -0.952 m, and the distance between you and the mirror ([tex]d_{o}[/tex]) is 1.0 m, we can substitute these values into the equation to calculate the magnification. Thus, m = -(-0.952)/1.0 = 0.952. The magnification is positive, indicating an upright image. To find the image height ([tex]h_{i}[/tex]), we multiply the magnification by the object height ([tex]h_{o}[/tex]). Given that the height of the cyclist ([tex]h_{o}[/tex]) is 1.5 m, we can calculate [tex]h_{i}[/tex] as [tex]h_{i}[/tex] = m * [tex]h_{o}[/tex] = 0.952 * 1.5 = 1.428 m. Therefore, the image height of the cyclist is approximately 1.428 m.

The expression for the wave function when y(x=12.5 cm, t) = 0;

y(x,t) = 3.75 sin (6.98x - 31.4t + π)

(a)The general expression for a sinusoidal wave is represented as;

where;

A is the amplitude;

k is the wave number (k = 2π/λ);

λ is the wavelength;

andx and t are the position and time variables, respectively.Now, given;

A = 3.75 cm (Amplitude)

f = 5.00 Hz (Frequency)y(0,t) = 0 when t = 0.;

This is the required expression for the wave function in Si unit, travelling along the negative direction of x-axis.

(b)From part (a), the required expression for the wave function is;

y(x,t) = 3.75 sin (6.98x - 31.4t) ----- (1)

Let the wave function be 0 when x = 12.5 cm.

Hence, substituting the values in equation (1), we have;

0 = 3.75 sin (6.98 × 12.5 - 31.4t);

⇒ sin (87.25 - 6.98x) = 0;

The type of force that exists between nucleons is the strong force. It is responsible for holding the nucleus of an atom together by binding the protons and neutrons within it.

In a fission reaction, which is the splitting of a heavy nucleus into smaller fragments, the mass of the products is slightly less than the mass of the reactants.

This phenomenon is known as mass defect. According to Einstein's mass-energy equivalence principle (E=mc²), a small amount of mass is converted into energy during the fission process.

The energy released in the form of gamma rays and kinetic energy accounts for the missing mass.

Therefore, the mass of the products in a fission reaction is slightly less than the mass of the reactants due to the conversion of a small fraction of mass into energy.

B. To find the velocity of the carts after the collision, we can use the principle of conservation of momentum. The total momentum before the collision is equal to the total momentum after the collision.

Before collision:

Momentum of A = mass of A * velocity of A = 2.0 kg * 50 m/s = 100 kg·m/s (to the right)

Momentum of B = mass of B * velocity of B = 4.0 kg * (-25 m/s) = -100 kg·m/s (to the left)

Total momentum before collision = Momentum of A + Momentum of B = 100 kg·m/s - 100 kg·m/s = 0 kg·m/s

After collision:

Let the final velocity of both carts be V (since they stick together).

Total momentum after collision = (Mass of A + Mass of B) * V

According to the conservation of momentum,

Total momentum before collision = Total momentum after collision

0 kg·m/s = (2.0 kg + 4.0 kg) * V

0 = 6.0 kg * V

V = 0 m/s

C. To find the kinetic energy lost during the collision, we can calculate the total initial kinetic energy and the total final kinetic energy.

Total initial kinetic energy = Kinetic energy of A + Kinetic energy of B

                          = (1/2) * mass of A * (velocity of A)^2 + (1/2) * mass of B * (velocity of B)^2

                          = (1/2) * 2.0 kg * (50 m/s)^2 + (1/2) * 4.0 kg * (-25 m/s)^2

                          = 2500 J + 1250 J

                          = 3750 J

Total final kinetic energy = (1/2) * (Mass of A + Mass of B) * (Final velocity)^2

                         = (1/2) * 6.0 kg * (0 m/s)^2

                         = 0 J

Kinetic energy lost during the collision = Total initial kinetic energy - Total final kinetic energy

                                       = 3750 J - 0 J

                                       = 3750 J

Final Speed: The final speed of the combined lump in an inelastic collision cannot be determined using the given information.

It requires additional data, such as the nature of the collision and the relative velocities of the lumps. Without this information, it is not possible to calculate the final speed as a fraction of the speed of light (e).

Final Mass: The final mass of the combined lump can be calculated by adding the individual masses together.

Since both lumps have a mass of 1,500 kg, the combined mass of the lump immediately after the collision would be 3,000 kg. There is no indication of a factor or value (2.45 m) that affects the calculation of the final mass, so it remains at 3,000 kg.

The hammer thrower can swing the 4.0 kg hammer around herself at a maximum speed of approximately 42.99 m/s without losing her grip, given her maximum force of 1550 N.

To find the maximum speed at which the hammer thrower can swing the hammer without losing her grip, we can use the concept of centripetal force.

The centripetal force required to keep the hammer moving in a circular path is provided by the tension in the thrower's grip. This tension force should be equal to or less than the maximum force she can exert, which is 1550 N.

The centripetal force is given by the equation:

F = (m * v²) / r

Where:

F is the centripetal force

m is the mass of the hammer (4.0 kg)

v is the linear velocity of the hammer

r is the radius of the circular path (1.9 m)

We can rearrange the equation to solve for the velocity:

v = √((F * r) / m)

Substituting the values:

v = √((1550 N * 1.9 m) / 4.0 kg)

v = √(7395 Nm / 4.0 kg)

v = √(1848.75 (Nm) / kg)

v ≈ 42.99 m/s

Therefore, the hammer thrower can swing the 4.0 kg hammer around herself at a maximum speed of approximately 42.99 m/s without losing her grip, given her maximum force of 1550 N.

The net electrostatic force on the charge in the top right corner of the square is 8.91 x 10⁶ N at an angle of 14.0° above the horizontal.

The expression for the electrostatic force between two charged spheres is:

F=k(q₁q₂/r²)

Where, k is the Coulomb constant, q₁ and q₂ are the charges of the spheres and r is the distance between their centers.

The magnitude of each force is:

F=k(q₁q₂/r²)

F=k(2.30C x 2.30C/(0.60m)²)

F=8.64 x 10⁶ N3. If F₁, F₂, and F₃ are the magnitudes of the forces acting along the horizontal and vertical directions respectively, then the net force along the horizontal direction is:

Fnet=F₁ - F₂

Since the charges in the top and bottom spheres are equidistant from the charge in the top right corner, their forces along the horizontal direction will be equal in magnitude and opposite in direction, so:

F/k(2.30C x 2.30C/(0.60m)²)

= 8.64 x 10⁶ N4.

The net force along the vertical direction is: F

=F₃

= F/k(2.30C x 2.30C/(1.20m)²)

= 2.16 x 10⁶ N5.

Fnet=√(F₁² + F₃²)

= √((8.64 x 10⁶)² + (2.16 x 10⁶)²)

= 8.91 x 10⁶ N6.

The direction of the net force can be obtained by using the tangent function: Ftan=F₃/F₁= 2.16 x 10⁶ N/8.64 x 10⁶ N= 0.25tan⁻¹ (0.25) = 14.0° above the horizontal

Two identical sinusoidal waves with wave lengths of 3.00 m travel in the same direction at a speed of 2.00 m/s. The second wave originates from the same point as the first, but at a later time. The minimum possible time interval between the starting moments of the two waves is approximately 0.2387 seconds.

To determine the minimum possible time interval between the starting moments of the two waves, we need to consider their phase difference and the condition for constructive interference.

Let's analyze the problem step by step:

Given:

   Wavelength of the waves: λ = 3.00 m

   Wave speed: v = 2.00 m/s

   Amplitude of the resultant wave: A_res = A (same as the amplitude of each initial wave)

First, we can calculate the frequency of the waves using the formula v = λf, where v is the wave speed and λ is the wavelength:

f = v / λ = 2.00 m/s / 3.00 m = 2/3 Hz

The time period (T) of each wave can be determined using the formula T = 1/f:

T = 1 / (2/3 Hz) = 3/2 s = 1.5 s

Now, let's assume that the second wave starts at a time interval Δt after the first wave.

The phase difference (Δφ) between the two waves can be calculated using the formula Δφ = 2πΔt / T, where T is the time period:

Δφ = 2πΔt / (1.5 s)

According to the condition for constructive interference, the phase difference should be an integer multiple of 2π (i.e., Δφ = 2πn, where n is an integer) for the resultant amplitude to be the same as the initial wave amplitude.

So, we can write:

2πΔt / (1.5 s) = 2πn

Simplifying the equation:

Δt = (1.5 s / 2π) × n

To find the minimum time interval Δt, we need to find the smallest integer n that satisfies the condition.

Since Δt represents the time interval, it should be a positive quantity. Therefore,the smallest positive integer value for n would be 1.

Substituting n = 1:

Δt = (1.5 s / 2π) × 1

Δt = 0.2387 s (approximately)

Therefore, the minimum possible time interval between the starting moments of the two waves is approximately 0.2387 seconds.

In the angular momentum conservation experiment, the data collected from the aluminum disk and steel ring were analyzed to determine if angular momentum is conserved.

The % difference between L₁ω₁ and L₂ω₂ was calculated to evaluate the conservation.

To determine if angular momentum is conserved, we need to compare the initial angular momentum (L₁ω₁) with the final angular momentum (L₂ω₂). The initial angular momentum is given by the product of the moment of inertia (l) and the angular velocity (ω) of the system.

For the aluminum disk, the moment of inertia (l) is calculated as 1/2 * mass * radius². Substituting the given values, we find l = 1/2 * 0.106 kg * (0.0445 m)².

For the steel ring, the moment of inertia (In) is calculated as 1/2 * mass * (r₁² + r₂²). Substituting the given values, we find In = 1/2 * 0.267 kg * (0.0143 m)² + (0.0445 m)².

Next, we calculate the angular momentum (L) using the formula L = l * ω. The initial angular momentum (L1) is determined using the initial moment of inertia (l) of the aluminum disk and the angular velocity (ω₁) of the system. The final angular momentum (L₂) is determined using the final moment of inertia (In) of the steel ring and the angular velocity (ω₂) of the system.

To obtain the % difference between L₁ω₁ and L₂ω₂, we calculate (L₂ω₂ - L₁ω₁) / [(L₁ω₁ + L₂ω₂) / 2] * 100.

By comparing the calculated % difference with a tolerance threshold, we can determine if angular momentum is conserved in the experiment. If the % difference is within an acceptable range, it indicates that angular momentum is conserved; otherwise, it suggests a violation of conservation.
