2. Based on diagram A (above), showing the ocular micrometer (top) and stage micrometer (bottom, calibrated for 0.1 mm and 0.01 mm ) aligned together, what is the distance, in microns ( μm ), of one ocular micrometer unit (calibration factor) using the 4X objective lens? Show your calculation and state the measurement of the calibration factor in microns ( μm). Calculation: A

The average velocity represents the displacement per unit time, which is a vector quantity. In this case, the average velocity of 7.03 m/s indicates that the car is traveling at a constant speed of 7.03 m/s in the positive direction.

To find the distance traveled by the car in 5.00 seconds, we can use the formula:

Distance = Average Velocity × Time

Given that the average velocity of the car is 7.03 m/s and the time is 5.00 seconds, we can substitute these values into the formula:

Distance = 7.03 m/s × 5.00 s

Distance = 35.15 m

Therefore, the car travels a distance of 35.15 meters in 5.00 seconds.

By multiplying the average velocity by the time, we find the distance traveled. Since the car is moving at a constant speed, the distance traveled is equal to the displacement. Displacement refers to the change in position of an object and is also a vector quantity. In this case, the car's displacement is 35.15 meters in the positive direction.

It's important to note that the term "average" implies that the car's velocity might have varied during the 5.00 seconds, but when averaged over that period, it gives a value of 7.03 m/s.

The downward force of the rails on the car when it is upside down at the top of the loop is equal to the car's weight, or 15,000 N.

The car's velocity at the top of the loop must be at least equal to the velocity needed to keep it from falling off the track. This velocity is called the "escape velocity" and is calculated using the following formula:

v_e = sqrt(2 * g * R)

where:

v_e is the escape velocity

g is the acceleration due to gravity (9.8 m/s^2)

R is the radius of the loop (7.5 m)

Plugging in these values, we get the following:

v_e = sqrt(2 * 9.8 m/s^2 * 7.5 m) = 12.1 m/s

This means that the car's velocity at the top of the loop must be at least 12.1 m/s. If the velocity is less than this, the car will fall off the track.

The force of the rails on the car is equal to the car's weight. This is because the car is accelerating towards the center of the loop, and the force of the rails is what is causing this acceleration.

The force of gravity is also acting on the car, but it is pointing down, so it does not contribute to the car's acceleration towards the center of the loop.

The car's weight is equal to its mass times the acceleration due to gravity. The car's mass is 1500 kg and the acceleration due to gravity is 9.8 m/s^2, so the car's weight is 15,000 N.

Therefore, the downward force of the rails on the car when it is upside down at the top of the loop is 15,000 N.

The radius of the path that the particle describes in the magnetic field is 0.683 mm.

When a charged particle moves through a magnetic field, it experiences a force perpendicular to both its velocity and the direction of the magnetic field. This force is called the Lorentz force.

The Lorentz force causes the particle to move in a circular path. The radius of the circular path is given by the equation r = m v / q B, where m is the mass of the particle, v is its velocity, q is its charge, and B is the strength of the magnetic field.

In this problem, we are given the following information:

Mass of the particle: 3.2 × 10^-26 kg

Charge of the particle: 1.602 × 10^-19 C

Strength of the magnetic field: 0.5 T

We are also given that the particle is accelerated due to a potential difference of 937 V. This means that the particle has a velocity of v = √2 × 937 V / 3.2 × 10^-26 kg = 1.3 × 10^7 m/s.

Substituting these values into the equation r = m v / q B, we get r = 3.2 × 10^-26 kg × 1.3 × 10^7 m/s / 1.602 × 10^-19 C × 0.5 T = 0.683 mm.

Therefore, the radius of the path that the particle describes in the magnetic field is 0.683 mm.

Laplace's equation and the Gaussian differential form are two closely related mathematical concepts. Laplace's equation can be derived from the Gaussian differential form by using certain mathematical manipulations. Here's how it's done: start with the Gaussian differential form: ∇ · (ε ∇V) = 0.

This is a vector equation that relates the divergence of the gradient of V to the permittivity ε. Next, we use the vector identity ∇ · (f∇g) = f∇²g + ∇f · ∇g to simplify the equation. This identity is known as the product rule for divergence and is a common tool in vector calculus.

Applying it to the Gaussian differential form, we get:ε∇²V + (∇ε) · (∇V) = 0.This equation relates the Laplacian of V to the gradient of ε. It is also known as the Poisson equation.

Next, we make the assumption that the permittivity ε is constant throughout the region of interest. This means that ∇ε = 0, and the equation simplifies to:ε∇²V = 0.

This is known as Laplace's equation. It states that the Laplacian of V is equal to zero, meaning that V is a harmonic function.

In summary, Laplace's equation can be derived from the Gaussian differential form by using the product rule for divergence and assuming that the permittivity is constant.

a) Using Faraday's law, E = Bo/√2 sin ωt âz ; b) Obtained value of the magnetic field B is the same as the original magnetic field B, which is B = Boz cos (ωt) ây ; c) There is no change in the magnetic field due to the electric field, and it is unchanged.

Using Ampere's law, the magnetic field created by an electric current or changing electric field can be calculated.

The formula for Ampere's Law is: ∮B.dl = µ₀I + µ₀ϵ₀d(ΦE) / dt

In this equation, B is the magnetic field, dl is a short segment of the loop's path, I is the current flowing through the path, ϵ₀ is the permittivity of free space, and µ₀ is the permeability of free space.

Solution:(a) We need to find the electric field E from the given magnetic field B.

Using Faraday's law, emf = - dΦ / dt

= - (d/dt)(B.A cos 0°)

= - (d/dt)(Boz cos(ωt) A cos 0°)

= - Boz (d/dt)(cos ωt) A cos 0°

=- Boz (-ωsin ωt) A cos 0°

= ωBoz sin ωt A cos 0°

The direction of the induced electric field E will be perpendicular to the magnetic field B and the area vector A.

Therefore, E = ωBoz A sin ωt âz

= Bo/√2 sin ωt âz

(b) We need to calculate the magnetic field B from the electric field E obtained above.

Using Ampere's law,∮B.dl = µ₀ϵ₀d(ΦE) / dt

We know, B.dl = B.A

= B dy dx ây

The path of integration is the rectangular loop, and its width is 'dx,' and its length is 'dy'.

Therefore,∮B.dl = B dy dx ây

= BdA ây

= B cos 90°

dA âz= B cos 90° dx dy âz

= BdV âz

Therefore, the equation becomes, B dx = µ₀ϵ₀(d/dt)(B cos 0° A cos 0°) dydx∫Bdx

= µ₀ϵ₀ ∫ (d/dt)(B cos 0° A cos 0°) dydx∫Bo cos 0° dx

= µ₀ϵ₀ ∫ (d/dt)(Boz cos ωt A cos 0°) dy∫Bo cos 0° dx

= µ₀ϵ₀ (Boz sin ωt A) ∫ dy∫Bo cos 0° dx

= µ₀ϵ₀ (Boz sin ωt A) (dL) Where dL is the length of the loop.

The obtained value of the magnetic field B is the same as the original magnetic field B, which is B = Boz cos (ωt) ây. Therefore, the obtained result matches with the original expression of the magnetic field.

(c) The obtained magnetic field B is the same as the original magnetic field B. Since the electric field E is perpendicular to the magnetic field B, the two fields are independent of each other. The magnetic field is the result of the current or the changing electric field, while the electric field is the result of the changing magnetic field. Therefore, there is no change in the magnetic field due to the electric field, and it is unchanged.

The speed/time graph for both projectiles will have a similar shape. The speed will decrease as the projectiles move upward against gravity, reaching zero at the maximum height, and then increase as they come back down. The time axis will be the same for both projectiles.

On the speed/time graph, the time at which each projectile reaches the maximum height can be identified as the point where the speed is zero. The time taken by each projectile to return to the point of launch can be determined by finding the time when the speed becomes equal to the initial velocity.

To calculate the maximum height using the graph, you can use the equation for vertical motion:

h = (v^2 - u^2) / (2g)

where h is the maximum height, v is the final velocity (which is zero at the maximum height), u is the initial velocity, and g is the acceleration due to gravity.

By analyzing the speed/time graph, you can determine the time at which the speed becomes zero, which corresponds to the time taken to reach the maximum height. Then, you can use this time value along with the initial velocity in the above equation to calculate the maximum height.

Given a four-vector in frame with the spacetime coordinate r = (5,1,3,0) meter, velocity vector v = (0.6,0.5,0) c, and four- momentum vector p = (12,6,8,0) GeV/c. Assuming frame o' moves with a speed of 0.8c in the -- direction with respect to frame O.

Using Lorentz transformation, obtain these four vectors (i.e., spacetime coordinate, velocity vector, and four-momentum) in frame O'.The four-vector transformation follows from the Lorentz transformation. For each vector, apply the standard transformation equations to obtain its values in the transformed frame O'.Transformation of spacetime coordinate r = (5,1,3,0) meter.

The transformed coordinate, r', can be found by using the following formula:

r'= γ(r-vt)Here,γ= 1/(sqrt(1-v²/c²)) ; and t=0, because the coordinate is at rest in the O' frame.

Putting values in the formula,γ= 1/(sqrt(1-v²/c²)) = 1/(sqrt(1-0.8²)) = 5/3.

Substituting r and t=0,r' = γ(r-vt) = (5/3)[(5,1,3,0)-(0.6,0.5,0)*0] = (25/3, 5/3, 15/3, 0) = (8.333, 1.667, 5, 0) meter.

Transformation of velocity vector v = (0.6,0.5,0) c.

The transformed velocity, v', can be found using the following formula:

v'= (v-u)/(1-v.u/c²)Here, v = (0.6,0.5,0) c; u = 0.8c (since frame O' is moving with a speed of 0.8c in the -- direction with respect to frame O); and c = 1.

Putting values in the formula,v'= (v-u)/(1-v.u/c²)= [(0.6,0.5,0) - 0.8(1,0,0)]/[1-(0.6)(0.8)-(0.5)(0)] = (0.185, -0.480, 0) c.

Thus, the velocity vector in frame O' is v' = (0.185, -0.480, 0) c.

Transformation of four-momentum vector p = (12,6,8,0) GeV/cThe transformed four-momentum, p', can be found using the following formula:

p' = γ(E/cp-uv/c²)Here, γ = 5/3, as before; E = c|p| = 10 GeV; cp = (12,6,8) GeV/c; and u = 0.8c, as before.

Putting values in the formula,p' = γ(E/cp-uv/c²) = (5/3)[(10/c)(12,6,8)-(0.8c)(1,0,0)] = (16.667, 5, 1.667, 0) GeV/c.

Thus, the four-momentum vector in frame O' is p' = (16.667, 5, 1.667, 0) GeV/c.

Given a four-vector in frame with the spacetime coordinate r = (5,1,3,0) meter, velocity vector v = (0.6,0.5,0) c, and four- momentum vector p = (12,6,8,0) GeV/c. Assuming frame o' moves with a speed of 0.8c in the -- direction with respect to frame O. Using Lorentz transformation, obtain these four vectors (i.e., spacetime coordinate, velocity vector, and four-momentum) in frame O'.

The Lorentz transformation, as described by the special theory of relativity, can be used to transform vectors and tensors between frames of reference that are moving relative to one another at constant velocities. The four-vector transformation follows from the Lorentz transformation.

For each vector, apply the standard transformation equations to obtain its values in the transformed frame O'.The first vector to transform is the spacetime coordinate r = (5,1,3,0) meter.

To solve this problem, we can apply the principles of conservation of momentum and conservation of kinetic energy.

(a) Find the speed of each asteroid after the collision:

1. Conservation of momentum:

Before the collision, the total momentum of the system is zero since asteroid B is initially at rest. After the collision, the total momentum of the system is still zero.

Let's assume the mass of each asteroid is m.

Before the collision:

Momentum of asteroid A = mass of asteroid A × velocity of asteroid A = m × 40.0 m/s

After the collision:

Momentum of asteroid A = mass of asteroid A × velocity of asteroid A (final)

Momentum of asteroid B = mass of asteroid B × velocity of asteroid B

Since the total momentum is conserved:

(m × 40.0 m/s) + (m × 0) = (m × velocity of asteroid A (final)) + (m × velocity of asteroid B)

Simplifying the equation:

40.0 = velocity of asteroid A (final) + velocity of asteroid B

2. Conservation of kinetic energy:

The initial kinetic energy of the system is given by:

Initial kinetic energy = (1/2) × mass of asteroid A × (velocity of asteroid A)^2

The final kinetic energy of the system is given by:

Final kinetic energy = (1/2) × mass of asteroid A × (velocity of asteroid A (final))^2 + (1/2) × mass of asteroid B × (velocity of asteroid B)^2

Since the collision is not perfectly elastic, some of the initial kinetic energy is lost. Therefore, the final kinetic energy will be less than the initial kinetic energy.

(b) What fraction of the original kinetic energy of asteroid A dissipates during this collision:

The fraction of the original kinetic energy dissipated is given by:

Fraction dissipated = (Initial kinetic energy - Final kinetic energy) / Initial kinetic energy

Now, let's calculate the values:

(a) To find the speed of each asteroid after the collision:

From the conservation of momentum:

40.0 = velocity of asteroid A (final) + velocity of asteroid B

From the given angles, we can use trigonometry to relate the velocities of the asteroids:

velocity of asteroid A (final) = velocity of asteroid A × cos(30°)

velocity of asteroid B = velocity of asteroid A × sin(30°) / sin(45°)

Substituting the trigonometric expressions into the momentum equation:

40.0 = velocity of asteroid A × cos(30°) + velocity of asteroid A × sin(30°) / sin(45°)

Now, we solve this equation to find the values of velocity of asteroid A (final) and velocity of asteroid B.

(b) To find the fraction of the original kinetic energy dissipated:

Calculate the initial kinetic energy using:

Initial kinetic energy = (1/2) × mass of asteroid A × (velocity of asteroid A)^2

Calculate the final kinetic energy using:

Final kinetic energy = (1/2) × mass of asteroid A × (velocity of asteroid A (final))^2 + (1/2) × mass of asteroid B × (velocity of asteroid B)^2

Finally, use the formula:

Fraction dissipated = (Initial kinetic energy - Final kinetic energy) / Initial kinetic energy

Performing these calculations will give you the specific values for the speeds of the asteroids after the collision and the fraction of the original kinetic energy dissipated.

The highest altitude reached by the projectile, measured from the surface, is 0.087 times the radius of Earth (Option A).

When a projectile is fired straight upward from Earth's surface, it experiences the force of gravity acting against its upward motion. The escape speed is the minimum speed required for an object to escape the gravitational pull of Earth and move into space. In this case, the projectile is fired with a speed that is 0.4 times the escape speed.

To determine the highest altitude reached by the projectile, we need to consider the energy conservation principle. At the highest point of its trajectory, the kinetic energy of the projectile will be zero. The initial kinetic energy of the projectile is given by (1/2)mv^2, where m is the mass of the projectile and v is its initial velocity. The potential energy of the projectile at its highest point is given by mgh, where h is the height from the surface of the Earth.

Since the projectile is fired straight upward, its final velocity at the highest point is zero. By equating the initial kinetic energy to the potential energy at the highest point, we can solve for the height h. The initial kinetic energy is (1/2)m(0.4v_esc)^2 and the potential energy is mgh. Setting these two equal, we have (1/2)m(0.4v_esc)^2 = mgh.

Canceling out the mass term and solving for h, we find h = (0.4v_esc)^2/(2g), where g is the acceleration due to gravity. The escape speed v_esc is given by √(2gR), where R is the radius of Earth.

Substituting the value of v_esc into the equation for h, we have h = (0.4√(2gR))^2/(2g). Simplifying this expression, we get h = 0.08R. Therefore, the highest altitude reached by the projectile, measured from the Earth's surface, is 0.08 times the radius of Earth (0.08 R).

(b) Find the sound intensity created by one such machine.

Since we have already found $I_{indv}$ in part a, we just have to substitute it into the formula:$$intensityIndv = 1.12 \times 10^{-3} W/m^2$$Thus, the sound intensity created by one such machine is $1.12 \times 10^{-3} W/m^2$.

(c) To find the sound decibel level when five such machines are running, we use the formula:$$I_1 = I_2 + I_3 + ... + I_n$$where $I_1$ is the intensity of the 5 machines running together, and $I_2$, $I_3$, and $I_n$ are intensities of the individual machines. Since we know the intensity of one machine, we can find the total intensity of five machines by multiplying by 5:$$I_1 = 5 \times 1.12 \times 10^{-3} = 5.6 \times 10^{-3} W/m^2$$To find the sound decibel level of this intensity, we use the formula for decibels in terms of intensity:$$dB = 10\log_{10}\frac{I}{I_0}$$where $I$ is the intensity in watts per square meter and $I_0$ is the threshold of hearing $10^{-12}$ W/m². Substituting $I = 5.6 \times 10^{-3} W/m^2$ and $I_0 = 10^{-12} W/m^2$ gives:$$dB = 10\log_{10}\frac{5.6 \times 10^{-3}}{10^{-12}} \approx 101.8$$Thus, the sound decibel level when five such machines are running is approximately $101.8$ dB.

The maximum magnitude permitted for the concentrated load P is 12000 lb.

To calculate the maximum magnitude of the concentrated load P that can be permitted on the cantilever beam, we need to consider the bending stress and the shearing stress.

Bending Stress:

The bending stress can be calculated using the formula:

σ_b = (M * c) / I

where:

σ_b is the bending stress

M is the moment applied to the beam

c is the distance from the neutral axis to the outermost fiber

I is the moment of inertia of the cross-section

Since we are dealing with a rectangular cross-section, the moment of inertia can be calculated as:

I = (w * d^3) / 12

where:

w is the width of the cross-section

d is the depth of the cross-section

Given:

w = B = 6 in

d = 20 in

I = 5333 in^4

Substituting the values, we have:

I = (6 * 20^3) / 12

5333 = 8000

Now, the distance c for a rectangular cross-section is equal to half the depth, so:

c = d / 2

c = 20 / 2

c = 10 in

Assuming the load P is applied at the end of the beam, the maximum bending moment is at the fixed end and its magnitude is PL. Therefore:

σ_b = (M * c) / I

σ_b = (P * L * c) / I

Shearing Stress:

The shearing stress can be calculated using the formula:

τ = V / A

where:

τ is the shearing stress

V is the shear force

A is the cross-sectional area

For a rectangular cross-section, the cross-sectional area is given by:

A = w * d

Given the allowable shearing stress is 100 psi, we can set up the equation:

τ = V / A

100 psi = P / (w * d)

Now, we can solve the equations simultaneously to find the maximum magnitude of the load P.

Let's substitute the values we know:

100 psi = P / (6 in * 20 in)

P = 100 psi * (6 in * 20 in)

P = 100 psi * 120 in^2

P = 12000 psi

Therefore, the maximum magnitude permitted for the concentrated load P is 12000 lb.

The acceleration the Earth experiences as a result of your jump is quite little in comparison to its enormous mass, even though the Earth pulls on you with an equal and opposite force. The Earth's consequent motion is minimal and invisible to our senses.

Due to the disparity in masses between you and the Earth, it appears as though the Earth is not moving when you jump into the air. For every action, there is an equal and opposite response, states Newton's third rule of motion. According to Newton's third law, when you jump up, you apply a force to the Earth, which then applies an equal and opposite force to you.

The mass of the Earth, however, is far more than your own. You accelerate in the opposite direction due to the force the Earth applies to you, which causes you to rise. The acceleration the Earth undergoes in reaction to your push, however, is small due to its enormous mass, making the Earth's motion undetectable.

The expression for the aerodynamic drag force FD acting on a turbine blade in terms of blade tip velocity u, air density p, and blade cross-sectional area A is: FD = k × u² × p × A

To derive an expression for the aerodynamic drag force FD acting on a turbine blade using dimensional analysis, we start by considering the variables involved and their dimensions.

Variables: FD: Aerodynamic drag force

u: Velocity of the blade tip

p: Density of air

A: Cross-sectional area of the blade

Dimensions:

[p]: Mass density (M × L⁻³)

Using dimensional analysis, we can express the relationship between these variables as:

FD = k × uᵃ × pᵇ × [tex]A^{c}[/tex]

where k is a dimensionless constant and a, b, c are exponents to be determined. Analyzing the dimensions of both sides of the equation, we have:

[M × L × T⁻²] = [L × T⁻¹]ᵃ × [M × L⁻³]ᵇ × [tex]L^{2c}[/tex]

Equating the dimensions on both sides, we get:

M¹ * L¹ × T⁻² = Lᵃ × T⁻ᵃ × Mᵇ × L⁻³ᵇ × [tex]L^{2c}[/tex]

Matching the dimensions of mass, length, and time separately, we have:

M: 1 = b

L: 1 = a - 3b + 2c

T: -2 = -a

From the equation -2 = -a, we find that a = 2.

Substituting a = 2 into the equation for L, we have:

1 = 2 - 3b + 2c

Simplifying further, we get:

-1 = -3b + 2c

Rearranging terms, we find:

3b - 2c = 1

Now we have a system of two equations:

b = 1

3b - 2c = 1

Solving this system, we find b = 1 and c = 1.

Therefore, the expression for the aerodynamic drag force FD acting on a turbine blade in terms of blade tip velocity u, air density p, and blade cross-sectional area A is:

FD = k × u² × p × A

where k is a dimensionless constant.

When a positive gauge pressure is doubled, the absolute pressure will be increased but not necessarily doubled.The pressure in a system is measured using a gauge which is relative to the surrounding environment's pressure.

The difference between the gauge pressure and the atmospheric pressure is referred to as gauge pressure. Gauge pressure is generally positive, indicating that it is higher than atmospheric pressure.What is absolute pressure?The sum of atmospheric and gauge pressure is referred to as absolute pressure. Absolute pressure is usually positive and larger than gauge pressure. When calculating the pressure of a vacuum, absolute pressure is negative because it is lower than atmospheric pressure.

The gauge pressure of a system varies depending on atmospheric conditions such as elevation. A gauge pressure of 0 is equivalent to atmospheric pressure, whereas an absolute pressure of 0 is a perfect vacuum. The atmospheric pressure in Denver, Colorado, which is roughly 1609 m above sea level, is lower than the atmospheric pressure in New York City, which is at sea level because of the difference in elevation.When a positive gauge pressure is doubled, the absolute pressure will be increased but not necessarily doubled.

For instance, if the gauge pressure of a system is 5 psi, the absolute pressure is 19.7 psi since atmospheric pressure is roughly 14.7 psi. If the gauge pressure is doubled from 5 psi to 10 psi, the absolute pressure would rise to 24.7 psi, which is an increase of 5 psi, but not a doubling of the absolute pressure. Therefore, the correct answer is option (c).

- The first part of the question is that y(0.5) ≈ -0.1925, which is obtained by applying Euler's method to the given differential equation y' = -2x - y with the initial condition y(0) = -1 and a step size of h = 0.1.

- For the second part of the question, the approximate value of sin(0.15) is found using Lagrange interpolation with the given data points sin(0.1) = 0.09983 and sin(0.2) = 0.19867. The Lagrange polynomial is constructed using these data points, and by substituting x = 0.15 into the polynomial, we find that sin(0.15) ≈ 0.149504.

To solve the first part of the question using Euler's method, we have the differential equation y' = -2x - y, an initial condition y(0) = -1, and a step size h = 0.1. We want to find the value of y at x = 0.5.

Using Euler's method, we can approximate the value of y at x = 0.5 by iterating the following steps:

⇒ Initialize the variables:

x = 0 (initial value)

y = -1 (initial condition)

h = 0.1 (step size)

target_x = 0.5 (the value of x at which we want to find y)

⇒ Iterate the following steps until x reaches the target_x:

a. Calculate the slope at the current point: y' = -2x - y

b. Update the values of x and y using the Euler's method:

  x = x + h

  y = y + h * y'

⇒ Once x reaches the target_x, we have the approximate value of y. Therefore, y(0.5) ≈ y.

Performing the above steps, we get:

x = 0.5

y = -0.1925

Therefore, y(0.5) ≈ -0.1925.

Now, let's move on to the second part of the question, which involves finding an approximate value of sin(0.15) using Lagrange interpolation with the given data points sin(0.1) = 0.09983 and sin(0.2) = 0.19867.

Lagrange interpolation is a method used to approximate a function value at a point within a given set of data points. Given two data points (x₁, y₁) and (x₂, y₂), the Lagrange polynomial can be constructed as follows:

P(x) = (x - x₂) / (x₁ - x₂) * y₁ + (x - x₁) / (x₂ - x₁) * y₂

Using the given data points, we can construct the Lagrange polynomial for sin(x):

P(x) = (x - 0.2) / (0.1 - 0.2) * sin(0.1) + (x - 0.1) / (0.2 - 0.1) * sin(0.2)

Substituting x = 0.15 into the polynomial, we can approximate sin(0.15):

P(0.15) = (0.15 - 0.2) / (0.1 - 0.2) * sin(0.1) + (0.15 - 0.1) / (0.2 - 0.1) * sin(0.2)

Calculating the above expression, we find:

P(0.15) ≈ 0.149504

Therefore, sin(0.15) ≈ 0.149504.

The magnitude of the short free span is approximately 0.00875 meters.

Given:

Factored load = 8 kPa

Alpha coefficient (α) = 250

Factored moment = 17.5 kNm/m

The short free span of a slab refers to the distance between supports where the moments and deflections are relatively small.

To find the short free span, we can use the formula:

Short free span (L) = (Factored moment / (Alpha coefficient * Factored load))

Substituting the given values:

L = (17.5 kNm/m) / (250 * 8 kPa)

First, we need to convert kNm to kN·m:
