The work done by friction until the rock climber lands on the shelf is approximately 105468.8 Joules.

To find the work done by friction on the rock climber, we need to calculate the change in the gravitational potential energy of the climber as she slides down.

The change in gravitational potential energy is given by the formula:

ΔPE = m * g * Δh

where:

ΔPE is the change in gravitational potential energy,

m is the mass of the rock climber (58 kg),

g is the acceleration due to gravity (approximately 9.8 m/s²), and

Δh is the change in height (186 m).

Substituting the values into the formula, we have:

ΔPE = 58 kg * 9.8 m/s² * (-186 m)

The negative sign indicates that the gravitational potential energy decreases as the climber descends.

Calculating the value, we find:

ΔPE = -105468.8 J

The magnitude of the electric field at a point midway between a -6.2 μC and a +5.8 μC charge, 10 cm apart, is approximately 1.0 × [tex]10^{4}[/tex] N/C.

To determine the electric field at the midpoint, we can consider the two charges as point charges and apply the principle of superposition. The electric field due to each charge will be calculated separately and then added vectorially.

The electric field due to a point charge can be calculated using the formula:

E = k * (Q / [tex]r^2[/tex])

Where E is the electric field, k is the electrostatic constant (8.99 × [tex]10^9 N m^2/C^2[/tex]), Q is the charge, and r is the distance from the charge.

For the -6.2 μC charge, the distance to the midpoint is 5 cm (half the separation distance of 10 cm). Substituting these values into the formula, we get:

E1 = (8.99 × [tex]10^9 N m^2/C^2[/tex]) * (-6.2 × [tex]10^{-6}[/tex] C) / [tex](0.05 m)^2[/tex]

Calculating this, we find E1 ≈ -1.785 × [tex]10^{4}[/tex] N/C.

For the +5.8 μC charge, the distance to the midpoint is also 5 cm. Substituting these values, we get:

E2 = (8.99 × [tex]10^9 N m^2/C^2[/tex]) * (5.8 × [tex]10^{-6}[/tex] C) / [tex](0.05 m)^2[/tex]

Calculating this, we find E2 ≈ 1.682 × [tex]10^{4}[/tex] N/C.

To find the net electric field at the midpoint, we add the magnitudes of E1 and E2 since they have opposite signs. The magnitude of the electric field is given by:

|E| = |E1| + |E2|

|E| ≈ |-1.785 × [tex]10^{4}[/tex] N/C| + |1.682 × [tex]10^{4}[/tex] N/C|

While oscillating, it is found to have a speed of 2.21 m/s as it passes through its equilibrium position.The amplitude of oscillation is approximately 0.555 m.The oscillator's total mechanical energy as it passes through a position that is 0.675 of the amplitude away from the equilibrium position is approximately 0.910 J.

To find the amplitude A of oscillation, we can use the formula for the kinetic energy of a spring oscillator:

Kinetic Energy = (1/2) × m × v^2

where m is the mass of the oscillator and v is its speed.

Using the values given, we have:

(1/2) × (1.55 kg) × (2.21 m/s)^2 = (1/2) × k × A^2

Simplifying the equation:

1.55 kg ×(2.21 m/s)^2 = 22.2 N/m × A^2

A^2 = (1.55 kg × (2.21 m/s)^2) / (22.2 N/m)

A^2 ≈ 0.3083 m^2

Taking the square root of both sides

A ≈ 0.555 m

The amplitude of oscillation is approximately 0.555 m.

Next, to calculate the oscillator's total mechanical energy Eot, we can use the formula:

Eot = Potential Energy + Kinetic Energy

At the position that is 0.675 of the amplitude away from the equilibrium position, the potential energy is equal to the total mechanical energy.

The locus of possible positions for the third charge Q2, given Q1 = 21 C and Q2 = -2.2 C, is represented by two separate curves on a graph, determined by the equation r2 = sqrt((2.2 * r1^2) / 21).

Given two point charges of magnitude Q at specific positions, the task is to determine the locus (possible positions) of a third charge Q2, such that the total electric field at a specific point is zero.

This locus represents the positions where the net electric field due to the two charges cancels out. The specific scenario is when the original charges are 21 and -2,2.

To find the locus of the possible positions of the third charge, we need to consider the electric field due to the two original charges. The electric field at any point due to a point charge is given by Coulomb's Law: E = k * (Q / r^2), where E is the electric field, k is the electrostatic constant, Q is the charge, and r is the distance from the charge.

For the total electric field to be zero at the point (0,1,0), the electric field vectors due to the two charges must have equal magnitudes but opposite directions. By setting up the equations for the electric fields due to each charge and considering their magnitudes and directions, we can determine the locus of possible positions for the third charge Q2.

Specifically, if the original charges are 21 and -2,2, the locus of possible positions for the third charge Q2 can be found by solving the equations derived from Coulomb's Law with the given charge magnitudes and positions. By solving these equations, we can determine the specific coordinates that satisfy the condition of zero net electric field at the point (0,1,0).

the height of the resultant wave formed by the interference of the two waves at the position z = 1.0 m and time t = 3.0 s is approximately 0.584 m.

To find the height of the resultant wave formed by the interference of the two waves at the position z = 1.0 m and time t = 3.0 s, we need to add the individual wave functions at that position and time.

Given:

y₁(x, t) = (0.25 m) sin[(4 m⁻¹)x + (3.5 s⁻¹)t + ϕ₁]

y₂(x, t) = (0.55 m) sin[(12 m⁻¹)(3 s⁻¹)t + ϕ₂]

Position: x = 1.0 m

Time: t = 3.0 s

Substituting the given values into the wave equations, we have:

y₁(1.0 m, 3.0 s) = (0.25 m) sin[(4 m⁻¹)(1.0 m) + (3.5 s⁻¹)(3.0 s) + ϕ₁]

y₂(1.0 m, 3.0 s) = (0.55 m) sin[(12 m⁻¹)(3 s⁻¹)(3.0 s) + ϕ₂]

To find the resultant wave height, we add the two wave heights:

y(x = 1.0 m, t = 3.0 s) = y₁(1.0 m, 3.0 s) + y₂(1.0 m, 3.0 s)

Now, substitute the values and evaluate:

y(x = 1.0 m, t = 3.0 s) = (0.25 m) sin[(4 m⁻¹)(1.0 m) + (3.5 s⁻¹)(3.0 s) + ϕ₁] + (0.55 m) sin[(12 m⁻¹)(3 s⁻¹)(3.0 s) + ϕ₂]

Calculate the values inside the sine functions:

(4 m⁻¹)(1.0 m) + (3.5 s⁻¹)(3.0 s) = 4 m⁻¹ + 10.5 m⁻¹ = 14.5 m⁻¹

(12 m⁻¹)(3 s⁻¹)(3.0 s) = 108 m⁻¹

The phase angles ϕ₁ and ϕ₂ are not given, so we cannot evaluate them. We'll assume they are zero for simplicity.

Substituting the calculated values and simplifying:

y(x = 1.0 m, t = 3.0 s) = (0.25 m) sin[14.5 m⁻¹] + (0.55 m) sin[108 m⁻¹]

Now, calculate the sine values:

sin[14.5 m⁻¹] ≈ 0.303

sin[108 m⁻¹] ≈ 0.924

Substituting the sine values and evaluating:

y(x = 1.0 m, t = 3.0 s) ≈ (0.25 m)(0.303) + (0.55 m)(0.924)

                      ≈ 0.07575 m + 0.5082 m

                      ≈ 0.58395 m

The constant torque required to bring the flywheel up to an angular speed of 400 rev/min in 8.00 s, starting from rest, is 995.688 N⋅m.

Step 1:

We need to determine the final angular velocity of the flywheel before we can determine the torque required. We can use the formula ωf = ωi + αt, where ωi is the initial angular velocity and α is the angular acceleration. In this case, ωi = 0 because the flywheel is starting from rest. We convert 400 rev/min to radians/s using the conversion factor 2π radians/1 rev.

ωf = (400 rev/min) (2π radians/1 rev) / (60 s/1 min) = 41.89 rad/s

We now know that the final angular velocity of the flywheel is 41.89 rad/s.

Step 2:

We can use the formula τ = Iα to determine the torque required. Rearranging the formula gives us α = τ/I. We can then use the formula ωf = ωi + αt to determine α, which we can then use to determine τ.

α = (ωf - ωi) / t

α = (41.89 rad/s - 0) / 8 s

α = 5.23625 rad/s²

τ = Iα

τ = (190 kg⋅m²) (5.23625 rad/s²)

τ = 995.688 N⋅m

The continuity equation states that the flow rate of an incompressible fluid through a tube is constant, so: Flow rate of blood in the artery = Flow rate of blood in the vein26 × 10⁻⁶ m³/s = 1.2 × 10⁻⁶ m³/s.

The velocity of blood in the vein is less than that in the artery.

Velocity of blood in the artery = Flow rate of blood in the artery / Area of artery.

Velocity of blood in the vein = Flow rate of blood in the vein / Area of vein

Pressure difference between the artery and vein = (1/2) × Density of blood × (Velocity of blood in the artery)² × (1/Area of artery² - 1/Area of vein²)

Pressure difference between the artery and vein = 120 - Pressure of vein.

The pressure difference between the artery and vein is equal to the change in potential energy.

However, we are ignoring the effects of potential energy, so the pressure difference between the artery and vein can be calculated as follows:

120 = (1/2) × 1,060 × (26 × 10⁻⁶ / [(π/4) × (1.66 × 10⁻³ m)²])² × (1/[(π/4) × (1.66 × 10⁻³ m)²] - 1/[(π/4) × (600 × 10⁻⁶ m)²])

120 = (1/2) × 1,060 × 12,580.72 × 10¹² × (1/1.726 × 10⁻⁶ m² - 1/1.1317 × 10⁻⁷ m²)120 = 16,017,300 Pa.

Therefore, the venous blood pressure is:

Pressure of vein = 120 - Pressure difference between the artery and vein

Pressure of vein = 120 - 16,017,300Pa

Pressure of vein = -16,017,180 Pa.

The magnitude of the resulting magnetic field at the point (0, 1.6 m, 0) is approximately 3.58 × 10⁻⁶ T (Tesla).

To calculate the magnetic field at the given point, we can use the Biot-Savart law. The Biot-Savart law states that the magnetic field created by a current-carrying wire is directly proportional to the current and inversely proportional to the distance from the wire.

Considering the first wire along the x-axis, the magnetic field it produces at the given point will have only the y-component. Using the Biot-Savart law, we find that the magnetic field magnitude is given by,

B1 = (μ₀I₁)/(2πr₁)

For the second wire perpendicular to the xy plane, the magnetic field it produces at the given point will have only the x-component. Using the Biot-Savart law again, we find that the magnetic field magnitude is given by,

B2 = (μ₀ * I₂) / (2π * r₂)

To find the resulting magnetic field, we use vector addition,

B = √(B₁² + B₂²)

Substituting the given values,

B = √(((4π × 10⁻⁷)60) / (2π1.6))² + ((4π × 10⁻⁷)69)/(2π * 6.6 m))²)

When light with a frequency of 5.4×10^14 Hz enters a liquid with a refractive index of 2.0, its frequency will remain the same.

The frequency of light refers to the number of complete oscillations or cycles it undergoes per unit of time. The index of refraction, denoted by "n," is a property of a medium that describes how light propagates through it.

It is defined as the ratio of the speed of light in a vacuum to the speed of light in the medium. In this case, the light enters a liquid with a refractive index of 2.0.

When light passes from one medium to another, its speed and wavelength change, while the frequency remains constant. The frequency of light is determined by the source and remains constant regardless of the medium it traverses.

Therefore, the frequency of light with a value of 5.4×10^14 Hz will remain the same when it enters the liquid with a refractive index of 2.0.In summary, the frequency of light with a vacuum frequency of 5.4×10^14 Hz will not change when it enters a liquid with a refractive index of 2.0.

The index of refraction only affects the speed and wavelength of light, while the frequency remains constant throughout different media.

The correct answer is option a) "The proton density in space is very low so close encounters are rare."

The lack of X-ray production by the electron can be attributed to the low density of protons in space, making close encounters between the electron and protons rare. X-rays are typically generated when high-energy electrons interact with matter, causing the electrons to decelerate rapidly and emit photons in the X-ray range. In this scenario, however, the scarcity of protons in the volume through which the electron is passing inhibits significant interactions.

Option b, suggesting that physics works differently in other parts of the universe, is not a plausible explanation in this context. The fundamental laws of physics, including the behavior of electrons and photons, remain consistent throughout the universe. Therefore, it is not a valid reason for the absence of X-ray production in this particular situation.

Option c proposes that the X-ray is shifted to a longer wavelength. However, this is not applicable because the absence of X-ray production cannot be attributed to a change in the wavelength of the emitted X-rays. Rather, it is primarily due to the low proton density.

Therefore, the correct answer is option a, as it accurately explains the lack of X-ray production by the electron passing through the volume with protons. The rare encounters between the electron and the low-density protons in space hinder the generation of X-rays.

When we flip the pages slowly, one page at a time, we can see the images moving. This is known as an optical illusion caused by the persistence of vision, which refers to the way our brain processes visual information. An image stays in our retina for approximately 1/16th of a second. When a new image appears before the previous one disappears, the brain blends the two images together, creating the illusion of motion.

Optical illusions can occur when our brain tries to make sense of the information it receives from our eyes. The image on the previous page continues to linger in our mind, and our brain automatically fills in the blanks. It is important to note that this effect is limited by the frame rate of our eyes and the speed at which we flip the pages. When we flip the pages too fast, the brain is unable to process the information and we are left with a blurry image.

Optical illusions are often used in animation and movies to create the illusion of motion. When images are shown in quick succession, it tricks the brain into thinking that the objects are moving. This is the same principle behind flipbooks and zoetropes, where a series of images are displayed in quick succession to create the illusion of motion.

The entire bottle of coke has a greater density than a glass of coke.

The density of the substance is determined by dividing the mass of the substance by its volume. When comparing the entire bottle of Coke to a glass of Coke, we can see that the bottle contains more mass and occupies a larger volume than the glass. The bottle is typically larger and can hold more liquid than a glass. Therefore, the mass of the Coke in the bottle is greater than the mass of the Coke in the glass, and the volume occupied by the Coke in the bottle is larger than the volume occupied by the Coke in the glass. Since the density is calculated by dividing mass by volume, and the mass of the Coke in the bottle is greater while the volume is also greater, the density of the entire bottle of Coke is higher compared to the density of the glass of Coke. Therefore, the entire bottle of coke has a greater density than a glass of coke.

The rate at which water flows out of the hole in the tank is approximately 1.51×[tex]10^{-3}[/tex] cubic meters per second.

To determine the rate at which water flows out of the hole in the tank, we can apply Bernoulli's equation, which relates the pressure, velocity, and height of a fluid in a flowing system.

First, let's find the velocity of the water flowing out of the hole.

The gauge pressure at the surface of the water is given as 5.00×10^3 Pa.

We can assume atmospheric pressure at the hole, so the total pressure at the hole is the sum of the gauge pressure and atmospheric pressure, which is 5.00×[tex]10^3[/tex] Pa + 1.01×[tex]10^5[/tex] Pa = 1.06×[tex]10^5[/tex] Pa.

According to Bernoulli's equation, the total pressure at the hole is equal to the pressure due to the water column plus the dynamic pressure of the flowing water:

P_total = P_water + (1/2)ρ[tex]v^2[/tex] + P_atm,

where P_total is the total pressure, P_water is the pressure due to the water column, ρ is the density of water, v is the velocity of the water flowing out of the hole, and P_atm is atmospheric pressure.

Since the tank is vertically oriented and the hole is at the bottom, the pressure due to the water column is ρgh, where h is the height of the water column above the hole. In this case, h = 0.900 m.

We can rewrite Bernoulli's equation as:

P_total = ρgh + (1/2)ρ[tex]v^2[/tex] + P_atm.

Now we can solve for v. Rearranging the equation, we get:

(1/2)ρ[tex]v^2[/tex] = P_total - ρgh - P_atm,

[tex]v^2[/tex] = 2(P_total - ρgh - P_atm)/ρ,

v = [tex]\sqrt[/tex](2(P_total - ρgh - P_atm)/ρ).

Now we can plug in the known values:

P_total = 1.06×[tex]10^5[/tex] Pa,

ρ = 1000 kg/[tex]m^3[/tex] (density of water),

g = 9.81 m/[tex]s^2[/tex] (acceleration due to gravity),

h = 0.900 m,

P_atm = 1.01×[tex]10^5[/tex] Pa (atmospheric pressure).

Substituting these values into the equation, we can calculate the velocity v of the water flowing out of the hole.

After finding the velocity, we can then calculate the rate at which water flows out of the hole using the equation for the volume flow rate:

Q = Av,

where Q is the volume flow rate, A is the cross-sectional area of the hole (π[tex]r^2[/tex], where r is the radius of the hole), and v is the velocity of the water.

Let's substitute the known values into the equations to calculate the velocity and volume flow rate.

First, let's calculate the velocity:

v =[tex]\sqrt[/tex](2(P_total - ρgh - P_atm)/ρ)

= [tex]\sqrt[/tex](2((1.06×10^5 Pa) - (1000 kg/m^3)(9.81 m/s^2)(0.900 m) - (1.01×10^5 Pa))/(1000 kg/m^3))

Simplifying the equation:

v ≈ 5.32 m/s

Next, let's calculate the cross-sectional area of the hole:

A = πr^2

= π(0.0190 m/2)^2

Simplifying the equation:

A ≈ 2.84×[tex]10^{-4}[/tex] [tex]m^2[/tex]

Finally, let's calculate the volume flow rate:

Q = Av

= (2.84×[tex]10^{-4}[/tex] [tex]m^2[/tex])(5.32 m/s)

Simplifying the equation:

Q ≈ 1.51×[tex]10^{-3}[/tex] [tex]m^3[/tex]/s

Therefore, the rate at which water flows out of the hole in the tank is approximately 1.51×[tex]10^{-3}[/tex] cubic meters per second.

At the escape velocity from the surface of the Earth, it would take approximately 14 minutes to drive from St. Petersburg to Los Angeles.

To determine the time it would take to travel from St. Petersburg to Los Angeles at the escape velocity from the surface of the Earth, we need to consider several factors.

First, we need to determine the distance between St. Petersburg and Los Angeles.

The approximate distance by road is around 5,827 miles or 9,375 kilometers.

Next, we need to calculate the escape velocity of Earth. The escape velocity is the minimum velocity an object needs to overcome Earth's gravitational pull and escape into space.

The escape velocity from the surface of Earth is approximately 11.2 kilometers per second or 6.95 miles per second.

Assuming we can maintain the escape velocity throughout the entire journey, we can calculate the time it would take to travel the distance using the formula:

Time = Distance / Velocity

Converting the distance to kilometers and the velocity to kilometers per hour, we can calculate the time:

Time = 9,375 km / (11.2 km/s * 3600 s/h) ≈ 0.23 hours or approximately 14 minutes.

Therefore, at the escape velocity from the surface of the Earth, it would take approximately 14 minutes to drive from St. Petersburg to Los Angeles.

It's important to note that this calculation assumes a straight path and a constant velocity, which may not be practically achievable.

The steady-state response of the system, given the specified input (magnitude 10) and transfer functions, is determined to be 7.75.

Given the transfer function for the given system:

G₁(s) = 1/(s+4)

G₂(s) = 1/(s+8)

The transfer function for the block diagram can be calculated as:

G(s) = C(s)/R(s) = G₁(s) / (1 + G₁(s) * G₂(s))

Considering the given values:

G(s) = C(s)/R(s) = (1/(s+4)) / (1 + ((1/(s+4)) * (1/(s+8))))

Putting the values in the above equation,

G(s) = 1/(s² + 12s + 32)

On taking the inverse Laplace transform of G(s), we get the time domain response of the system.

C(s) = G(s) * R(s) * (1 - E(s))

C(s) = (10/s) * (1 - (1/s)) * (1/s) * (1/(s² + 12s + 32))

The expression for C(s) can be written as:

C(s) = (10/s²) - (10/(s² * (s+4))) + (1/(s² + 12s + 32))

The above expression can be split into partial fractions. Let's say:

A/(s²) + B/s + C/(s+4) + D/(s+8) = (10/s²) - (10/(s² * (s+4))) + (1/(s² + 12s + 32))

On solving the above equation,

A = 10

B = 0.75

C = -2.5

D = 2.75

Therefore:

C(s) = (10/s²) + (0.75/s) - (2.5/(s+4)) + (2.75/(s+8))

Taking the inverse Laplace transform of C(s),

The response of the system when the unit step is applied is given by:

C(s) = 10(t - 1)e^(-4t) - 0.75e^(-2t) + 2.5e^(-4t) - 2.75e^(-8t)

Finally, the steady-state response of the given system is given by the final value of the response.

The final value theorem is given by:

lim s->0 sC(s) = lim s->0 s(10/s²) + lim s->0 s(0.75/s) - lim s->(-4) (2.5/(s+4)) + lim s->(-8) (2.75/(s+8))

Putting the values in the above equation,

lim s->0 sC(s) = 7.75

4. The power released by each resistance R1, R2, and R can be calculated using the formula, P = I^2R.

For R1, P = I^2R = 0.25^2 x 10 = 0.625 W.
For R2, P = I^2R = 0.25^2 x 20 = 1.25 W.
For R, P = I^2R = 0.25^2 x 40 = 2.5 W.

5. The total power released by resistors R1, R2, and R is 4.375 W (0.625 + 1.25 + 2.5 = 4.375 W), which is less than the power provided by the battery to the system (1.25 W). This indicates that some power is being lost in the circuit, possibly due to factors like internal resistance of the battery and resistance of wires and connections.

Part A:Given data: Diameter of the hole, d = 1.34 cm, Radius, r = d/2 = 0.67 cm

The formula to calculate the cross-sectional area of the hole is,

A = πr²

Where, π = 3.1416 and r is the radius of the hole.

Substitute the given values of π and r to get the answer.

A = 3.1416 × (0.67 cm)²= 1.4138 cm²

Cross-sectional area of the hole is 1.4138 cm².

Part B: Coefficient of linear expansion for steel, α = 1.2 × 10⁻⁵ (°C)⁻¹Change in temperature of the plate, ΔT = 170°C - 27°C = 143°C

From the coefficient of linear expansion, we know that, For a temperature change of 1°C, the length of a steel rod increases by 1.2 × 10⁻⁵ times its original length.

So, for a temperature change of ΔT = 143°C, the length of the steel rod increases by,ΔL = αL₀ΔTWhere, L₀ is the original length of the rod.

Since the rod is a steel plate with a hole, the cross-sectional area of the hole will also increase due to temperature change.

So, we can use the formula of volumetric expansion to find the change in volume of the hole.

Then, we can divide this change in volume by the original length of the plate to find the change in the cross-sectional area of the hole.

Volumetric expansion of the hole is given by,ΔV = V₀ α ΔTWhere, V₀ is the original volume of the hole.

Change in the cross-sectional area of the hole is given by,ΔA = ΔV/L₀

From Part A, we know that the original cross-sectional area of the hole is 1.4138 cm².

So, the original volume of the hole is,V₀ = A₀ L₀ = 1.4138 cm² × L₀Now, we can substitute the given values of α, ΔT, L₀, and A₀ to calculate the change in cross-sectional area.

ΔV = V₀ α ΔT= (1.4138 cm² × L₀) × (1.2 × 10⁻⁵ (°C)⁻¹) × (143°C)ΔA = ΔV/L₀= [(1.4138 cm² × L₀) × (1.2 × 10⁻⁵ (°C)⁻¹) × (143°C)] / L₀= 0.2402 cm²Increase in cross-sectional area of the hole is 0.2402 cm².

Hence, the cross-sectional area of the hole when the temperature of the plate is increased to 170°C is 1.4138 cm² + 0.2402 cm² = 1.6540 cm² (approx).

The moment of inertia of the blades of a wind turbine, the work done by the wind, and the angular speed of the blades are to be determined.

1. The moment of inertia of the blades of a wind turbine:

The moment of inertia of the three equally spaced rods rotating about their ends is given by:

I = 3 × I₀

where I₀ is the moment of inertia of one rod. The moment of inertia of one rod is given by:

I₀ = (1/12)ML²

where M = 926 lbs and L = 115 ft = 1380 in.

Substituting the values, we have:

I₀ = (1/12)(926)(1380)² in⁴

Hence,

I = 3I₀ = 3(1/12)(926)(1380)² = 4.4 × 10⁹ in⁴

The moment of inertia of the blades of the wind turbine is 4.4 × 10⁹ in⁴.

W = (1/2)Iω²

where ω is the angular velocity and I is the moment of inertia. The initial angular velocity is 0, and the final angular velocity is 25 rpm, which is equal to (25/60) × 2π rad/s = 26.18 rad/s.

Substituting I and ω, we get:

W = (1/2)Iω² = (1/2)(4.4 × 10⁹)(26.18)² = 3.13 × 10¹² in²/s²

The work done by the wind is 3.13 × 10¹² in²/s².

3. The angular speed of the blades:

The moment of inertia of the blades is given by:

I = (1/12)ML²

where M = 926 lbs and L = 30 m = 1181.10 in.

Angular speed ω is given by:

ω = √(2W/I)

where W is the work done calculated above.

Substituting the values, we get:

ω = √[(2 × 3.13 × 10¹²)/(1/12)(926)(1181.10)²] = 54.1 rpm
