Exercise 13.11. If V = C/r", obtain the functional dependence of the Born scattering amplitude on the scattering angle. Discuss the reasonableness of the result qualitatively. What values of n give a meaningful answer?

Answers

Answer 1

23)In exercise 13.11, we are given the potential V as a function of the distance r, specifically V = C/r. The task is to determine the functional dependence of the Born scattering amplitude on the scattering angle. Additionally, we need to discuss the reasonableness of the result qualitatively and identify the values of n that give a meaningful answer.

The Born scattering amplitude represents the scattering of particles due to a given potential. To obtain its functional dependence on the scattering angle, we need to analyze the behavior of the potential V = C/r. The scattering amplitude is typically expressed in terms of the differential cross-section, which relates the scattering angle to the amplitude.

Qualitatively, the result of the scattering amplitude for the given potential V = C/r can be reasoned as follows: Since the potential depends inversely on the distance, it implies that the scattering amplitude will have a dependence on the inverse of the scattering angle. This suggests that the amplitude will decrease as the scattering angle increases.

The values of n that give a meaningful answer depend on the specific scattering process and potential being considered. In general, meaningful values of n would be those that are physically meaningful and applicable to the system under study. It is important to consider the physical context and limitations of the problem to determine the appropriate values of n that provide meaningful insights into the scattering process.

A parallel-plate capacitor is made from two aluminum-foil sheets, each 7.7 cm wide and 5.3 m long. Between the sheets is a Teflon strip of the same width and length that is 4.4×10−2 mm thick.What is the capacitance of this capacitor? (The dielectric constant of Teflon is 2.1.)

Answers

The capacitance of this capacitor is approximately 3.092 x 10^(-11) F.

The capacitance of a parallel-plate capacitor can be calculated using the formula:

C = (ε₀ * εᵣ * A) / d

Where:

C is the capacitance,

ε₀ is the permittivity of free space (8.85 x 10^(-12) F/m),

εᵣ is the relative permittivity (dielectric constant) of the material,

A is the area of overlap between the plates,

d is the distance between the plates.

this case, the area of overlap between the plates (A) can be calculated as the product of the width (w) and length (l) of the aluminum-foil sheets:

A= w * l = 0.077 m * 5.3 m = 0.4071 m²

The distance between the plates (d) is given as 4.4 x 10^(-5) m.

Now, we can substitute the values into the formula to calculate the capacitance:

C = (8.85 x 10^(-12) F/m * 2.1 * 0.4071 m²) / (4.4 x 10^(-5) m)

C ≈ 3.092 x 10^(-11) F

Therefore, the capacitance of this capacitor is approximately 3.092 x 10^(-11) F.

A thin rod has a length of 0.268 m and rotates in a circle on a frictionless tabletop. The axis is perpendicular to the length of the rod at one of its ends. The rod has an angular velocity of 0.913rad/s and a moment of inertia of 1.26×10^−3 kg⋅m 2 . A bug standing on the axis decides to crawl out to the other end of the rod. When the bug (whose mass is 5×10^ −3 kg ) gets where it's going. what is the change in the angular velocity of the rod?

Answers

Given, the angular velocity of a thin rod with length 0.268 m and moment of inertia of 1.26 × 10⁻³  kg m² is 0.913 rad/s, the change in angular velocity of the rod is 174.79 rad/s.

Explanation;

The angular velocity of a thin rod with length 0.268 m and moment of inertia of 1.26 × 10⁻³  kg m² is 0.913 rad/s.

A bug with mass 5 × 10⁻³  kg crawls from the axis to the opposite end of the rod, causing the angular velocity to change.

We are to determine the change in angular velocity of the rod.

Let's begin by using the principle of conservation of angular momentum, which states that the total angular momentum of a system remains constant if no external torque acts on it. We have:

                 L1 = L2

where L1 = initial angular momentum of the rod with bug on the axis

           L2 = final angular momentum of the rod with the bug at the opposite end of the rod.

The initial angular momentum of the rod is:

           L1 = Iω1

where I = moment of inertia of the rod

         ω1 = initial angular velocity of the rod

Therefore,

            L1 = 1.26 × 10⁻³ kg m² × 0.913 rad/s

           L1 = 1.149 × 10⁻³  Nms.

Since the bug is on the axis, its moment of inertia is zero. Hence, it has zero initial angular momentum.

The final angular momentum of the system is:

          L2 = (I + m) ω2

   where m = mass of the bug

             ω2 = final angular velocity of the rod with the bug at the opposite end of the rod

Therefore,

           L2 = (1.26 × 10⁻³  kg m² + 5 × 10⁻³  kg) × ω2

           L2 = 6.5 × 10⁻⁶  ω2

The change in angular momentum of the rod is:

           ΔL = L2 - L1ΔL

                = 6.5 × 10⁻⁶  ω2 - 1.149 × 10⁻³  Nms

          ΔL = -1.149 × 10⁻³ Nms + 6.5 × 10⁻⁶  ω2

          ΔL = -1.1425 × 10⁻³  Nms + 6.5 × 10⁻⁶ ω2

Finally, we apply the principle of conservation of angular momentum as follows:

              ΔL = L2 - L1

                    = 0

Since there is no external torque acting on the system, the change in angular momentum is zero.

Thus,

           -1.1425 × 10⁻³  Nms + 6.5 × 10−6 ω2 = 0

                               ω2 = 175.7 rad/s

The change in angular velocity of the rod is:

               Δω = ω2 - ω1

               Δω = 175.7 rad/s - 0.913 rad/s

                Δω = 174.79 rad/s

Answer: The change in angular velocity of the rod is 174.79 rad/s.

When throwing a ball, your hand releases it at a height of 1.0 m above the ground with velocity 6.8 m/s in direction 61° above the horizontal.
A.) How high above the ground (not your hand) does the ball go?
B.) At the highest point, how far is the ball horizontally from the point of release?

Answers

The ball reaches a maximum height of approximately 1.122 meters above the ground.

At the highest point, the ball is approximately 2.496 meters horizontally away from the point of release.

We'll use the vertical component of the initial velocity to determine the maximum height reached by the ball.

Initial vertical velocity (Vy) = 6.8 m/s * sin(61°)

Acceleration due to gravity (g) = 9.8 m/s²

Using the kinematic equation:

Vy^2 = Uy^2 + 2 * g * Δy

Where:

Vy = final vertical velocity (0 m/s at the highest point)

Uy = initial vertical velocity

g = acceleration due to gravity

Δy = change in vertical position (height)

Rearranging the equation, we get:

0 = (6.8 m/s * sin(61°))^2 + 2 * 9.8 m/s² * Δy

Simplifying and solving for Δy:

Δy = (6.8 m/s * sin(61°))^2 / (2 * 9.8 m/s²)

Δy ≈ 1.122 m

Therefore, the ball reaches a maximum height of approximately 1.122 meters above the ground.

b) We'll use the horizontal component of the initial velocity to determine the horizontal distance traveled by the ball.

Initial horizontal velocity (Vx) = 6.8 m/s * cos(61°)

Time taken to reach the highest point (t) = ? (to be calculated)

Using the kinematic equation:

Δx = Vx * t

Where:

Δx = horizontal distance traveled

Vx = initial horizontal velocity

t = time taken to reach the highest point

The time taken to reach the highest point is determined solely by the vertical motion and can be calculated using the equation:

Vy = Uy - g * t

Where:

Vy = final vertical velocity (0 m/s at the highest point)

Uy = initial vertical velocity

g = acceleration due to gravity

Rearranging the equation, we get:

t = Uy / g

Substituting the given values:

t = (6.8 m/s * sin(61°)) / 9.8 m/s²

t ≈ 0.689 s

Now we can calculate the horizontal distance traveled using Δx = Vx * t:

Δx = (6.8 m/s * cos(61°)) * 0.689 s

Δx ≈ 2.496 m

Therefore, at the highest point, the ball is approximately 2.496 meters horizontally away from the point of release.

A CD can be modeled like a solid disk with a radius of 6.0 cm and a mass of 12g. If a CD is placed at the top of the slope and rolls down to the bottom without slipping or any rolling friction, what would the speed at the bottom be?

Answers

The speed at the bottom of the slope is 3.10m/s when a CD is placed at the top of the slope and rolls down to the bottom without slipping or any rolling friction.

Given that a CD can be modeled like a solid disk with a radius of 6.0 cm and a mass of 12 g. A 1.5 m long slope is set at an angle 25° above the horizontal. If a CD is placed at the top of the slope and rolls down to the bottom without slipping or any rolling friction, the speed at the bottom is calculated as follows:

Firstly, find the potential energy of the CD:

PE = mgh where m = 12g, h = 1.5 sin 25 = 0.6167m (height of the slope), and g = 9.8m/s²

PE = (12/1000) x 9.8 x 0.6167

PE = 0.0762J

The potential energy gets converted into kinetic energy at the bottom of the slope.

KE = 1/2 mv² where m = 12g and v = speed at the bottom

v = sqrt((2KE)/m)

The total energy is conserved, so

KE = PE

v = sqrt((2PE)/m)

Now, the speed at the bottom of the slope is:

v = sqrt((2 x 0.0762)/0.012)

v = 3.10m/s

Therefore, the speed at the bottom of the slope is 3.10m/s when a CD is placed at the top of the slope and rolls down to the bottom without slipping or any rolling friction.

Answers

A standing wave is set up on a string of length L, fixed at both ends. If 4-loops are observed when the wavelength is a = 1.5 m, the length of the string is 3 meters.

In a standing wave on a string fixed at both ends, the number of loops or antinodes (points of maximum amplitude) is related to the wavelength and the length of the string.

The relationship between the number of loops (n), the wavelength (λ), and the length of the string (L) is given by the equation:

n = 2L/λ

In this case, you mentioned that 4 loops are observed when the wavelength is 1.5 m. We can substitute these values into the equation and solve for the length of the string (L):

4 = 2L/1.5

To find L, we can rearrange the equation:

2L = 4 × 1.5

2L = 6

L = 6/2

L = 3 meters

when an apple of 0.2kg is placed on a scale in a store, the scale
starts to oscillate at 4.8Hz. what is the force constant of the
scale

Answers

To determine the force constant, we need additional information such as the displacement or the restoring force exerted by the scale. The force constant of the scale is approximately 9.56 N/m.

The force constant of the scale can be determined using Hooke's law, which states that the force exerted by a spring is proportional to the displacement from its equilibrium position. The equation for Hooke's law is: F = -k * x

Where F is the force applied, k is the force constant (also known as the spring constant), and x is the displacement from the equilibrium position.

In this case, when the apple is placed on the scale, it causes the scale to oscillate. The oscillation frequency (f) is given as 4.8 Hz.

The relationship between the force constant (k) and the oscillation frequency (f) of a simple harmonic oscillator is:

k = (2 * pi * f)^2 * m

Where m is the mass attached to the spring (in this case, the mass of the apple, which is 0.2 kg).

Substituting the values, we have:

k = (2 * pi * 4.8 Hz)^2 * 0.2 kg

k ≈ 9.56 N/m

Therefore, the force constant of the scale is approximately 9.56 N/m.

Answers

To analyze the time complexity of the given algorithm with the recurrence relation T(n) = 2T([n/2]) + n, we can prove its function form T(n) = Θ(n·lg(n)). Using induction, we establish that T(n) has the form T(2^k) = 2^k(T(1) + k).

By applying the Big O notation and using the multiplication rule and results from lecture materials, we can prove that T(n) = O(n·lg(n)). T(1) = O(1) suggests that the time complexity for a problem of size 1 is constant, regardless of the partitioning process involved.

(i) To prove the function form T(n) = T(2^k) = 2^k(T(1) + k) via induction:

Basis step (k = 1): When k = 1, n = 2^1 = 2, and T(n) = T(2) = 2T([2/2]) + 2 = 2T(1) + 2. Thus, the basis step holds.

Inductive hypothesis: Assume that for some k = m, the function form holds: T(2^m) = 2^m(T(1) + m).

Inductive step (k = m+1):We need to show that if the hypothesis holds for k = m, then it also holds for k = m+1.

When k = m+1, n = 2^(m+1) = 2*2^m = 2n', where n' = 2^m.

Using the given recurrence relation, we have:

T(n) = 2T([n/2]) + n

     = 2T([2n'/2]) + 2n'

     = 2T(n') + 2n'

     = 2(2^m(T(1) + m)) + 2n'   (by the inductive hypothesis)

     = 2^(m+1)(T(1) + m) + 2n'

     = 2^(m+1)(T(1) + (m+1))

Thus, the inductive step holds.

(ii) To prove that T(n) = O(n·lg(n)):

Using the function form T(n) = T(2^k) = 2^k(T(1) + k), we can substitute n = 2^k and T(1) = c (a constant) into the equation.

T(n) = 2^k(T(1) + k)

    = 2^k(c + k)

To analyze the time complexity, we can drop the smaller terms and consider the dominant term, which is 2^k*k.

Since n = 2^k, we have k = lg(n), so we can rewrite the equation as:

T(n) = 2^k*k

    = n*lg(n)

Therefore, T(n) = O(n·lg(n)).

(iii) If the algorithm involves a partitioning process and T(1) = O(1), it means that the time complexity for processing a problem of size 1 is constant. This suggests that the partitioning process has a relatively efficient and consistent time complexity, regardless of the problem size. In other words, the algorithm's performance does not significantly vary when dealing with small inputs, indicating a potentially well-designed partitioning scheme that efficiently handles the base case.

A hollow square steel tube has a height and width dimension of 5 in and a wall thickness of 0.4 in. and an original length of 8 in. The tube is loaded with 44000 lb. in compression and is shortened by 0.0017 in. as a result of the load. Determine the Modulus of Elasticity of the steel with 1-decimal place accuracy.E= _______ x10^6
(to 1 decimal place)

Answers

The Modulus of Elasticity of the steel with 1-decimal place accuracy is 0.0017 in / 8 in

To determine the modulus of elasticity (E) of the steel, we can use Hooke's law, which states that the stress (σ) is directly proportional to the strain (ε) within the elastic limit.

The stress (σ) can be calculated using the formula:

σ = F / A

Where:

F is the force applied (44000 lb in this case)

A is the cross-sectional area of the steel tube.

The strain (ε) can be calculated using the formula:

ε = ΔL / L0

Where:

ΔL is the change in length (0.0017 in)

L0 is the original length (8 in)

The modulus of elasticity (E) can be calculated using the formula:

E = σ / ε

Now, let's calculate the cross-sectional area (A) of the steel tube:

The outer dimensions of the tube can be calculated by adding twice the wall thickness to each side of the inner dimensions:

Outer height = 5 in + 2 × 0.4 in = 5.8 in

Outer width = 5 in + 2 × 0.4 in = 5.8 in

The cross-sectional area (A) is the product of the outer height and outer width:

A = Outer height × Outer width

Substituting the values:

A = 5.8 in × 5.8 in

A = 33.64 in²

Now, we can calculate the stress (σ):

σ = 44000 lb / 33.64 in²

Next, let's calculate the strain (ε):

ε = 0.0017 in / 8 in

Finally, we can calculate the modulus of elasticity (E):

E = σ / ε

The three finalists in a contest are brought to the centre of a large, flat field. Each is given a metre stick, a compass, a calculator, a shovel and the following three displacements: 72.4 m, 32.0° east of north;

Answers

The contestant calculates the resultant displacement by adding the three given displacements vectorially.

To determine the location of the buried keys, the contestant needs to calculate the resultant displacement by adding the three given displacements together. Here's how she can calculate it:

1. Start by converting the given displacements into their respective vector form. Each vector can be represented as a combination of horizontal (x) and vertical (y) components.

For the first displacement:

Magnitude: 72.4 m

Direction: 32.0° east of north

To find the horizontal and vertical components, we can use trigonometric functions. The eastward component can be found using cosine, and the northward component can be found using sine.

Horizontal component: 72.4 m * cos(32.0°)

Vertical component: 72.4 m * sin(32.0°)

For the second displacement:

Magnitude: 57.3 m

Direction: 36.0° south of west

To find the horizontal and vertical components, we use the same approach:

Horizontal component: 57.3 m * cos(180° - 36.0°)  [180° - 36.0° is used because it's south of west]

Vertical component: 57.3 m * sin(180° - 36.0°)

For the third displacement:

Magnitude: 17.8 m

Direction: Straight south

The horizontal component for this displacement is 0 since it's purely vertical, and the vertical component is simply -17.8 m (negative because it's south).

2. Add up the horizontal and vertical components separately for all three displacements:

Total horizontal component = Horizontal component of displacement 1 + Horizontal component of displacement 2 + Horizontal component of displacement 3

Total vertical component = Vertical component of displacement 1 + Vertical component of displacement 2 + Vertical component of displacement 3

3. Calculate the magnitude and direction of the resultant displacement using the total horizontal and vertical components:

Resultant magnitude = √(Total horizontal component^2 + Total vertical component^2)

Resultant direction = arctan(Total vertical component / Total horizontal component)

The contestant needs to calculate these values to determine the location where the keys to the new Porsche are buried.

The complete question should be:

The three finalists in a contest are brought to the center of a large, flat field. Each is given a meter stick, a compass, a calculator, a shovel, and (in a different order for each contestant) the following three displacements:

An electron has a total energy of 2.38 times its rest energy. What is the momentum of this electron? (in) Question 5 A proton has a speed of 48 km. What is the wavelength of this proton (in units of pm)? 8

Answers

(a) The momentum of the electron is 2.16 times its rest momentum.(b) The wavelength of the proton is 8246 picometers.

(a) The momentum of an electron with a total energy of 2.38 times its rest energy:

E² = (pc)² + (mc²)²

Given that the total energy is 2.38 times the rest energy, we have:

E = 2.38mc²

(2.38mc²)² = (pc)² + (mc²)²

5.6644m²c⁴ = p²c² + m²⁴

4.6644m²c⁴ = p²c²

4.6644m²c² = p²

Taking the square root of both sides:

pc = √(4.6644m²c²)

p = √(4.6644m²c²) / c

p = √4.6644m²

p = 2.16m

The momentum of the electron is 2.16 times its rest momentum.

(b)

To calculate the wavelength of a proton with a speed of 48 km/s:

λ = h / p

The momentum of the proton can be calculated using the formula:

p = mv

p = (1.6726219 × 10⁻²⁷) × (48,000)

p = 8.0333752 × 10⁻²³ kg·m/s

The wavelength using the de Broglie wavelength formula:

λ = h / p

λ = (6.62607015 × 10⁻³⁴) / (8.0333752 × 10⁻²³ )

λ ≈ 8.2462 × 10⁻¹²

λ ≈ 8246 pm

All three bulbs are identical and so are the two batteries. Comparing the brightness of the bulbs willkll be D. A less than B equals C

How to explain the information

If all three bulbs are identical and so are the two batteries, then all three bulbs will be equally bright. The brightness of a light bulb is determined by the amount of current flowing through it, and the current flowing through each bulb will be the same since they are all connected in parallel. Therefore, all three bulbs will be equally bright.

A baseball is batted at an angle into the air. Once airborne, and ignoring air drag, what is the ball’s acceleration vertically? horizontally?
At what part of its tragectory does the baseball have a minimum speed?

Answers

1. Assuming negligible air resistance, the horizontal component along the path of the projectile remains the same. The correct answer is option C.

2. When no air resistance acts on a fast-moving baseball, its acceleration is a combination of constant horizontal motion and accelerated downward motion. The correct answer is option B.

3. Neglecting air drag, a ball tossed at an angle of 30° with the horizontal will go as far downrange as one that is tossed at the same speed at an angle of 60 °. The correct answer is option B.

4. Once airborne, and ignoring air drag, the ball's acceleration vertically is downward and horizontally is zero

5. The baseball has a minimum speed at the highest point in its trajectory.

1) The horizontal component of the velocity of a projectile remains the same throughout its motion, assuming negligible air resistance.

This is because there is no horizontal force acting on the projectile to change its velocity. The only force acting in the horizontal direction is the initial velocity, which remains constant in the absence of external forces.

Therefore, the answer is C) remains the same.

2) In the absence of air resistance, the horizontal component of the velocity remains constant since there is no horizontal force acting on the projectile. This is known as the principle of inertia.

However, in the vertical direction, the force of gravity acts on the baseball, causing it to accelerate downward. The acceleration due to gravity is constant and equal to g (approximately 9.8 m/s² near the surface of the Earth).

As a result, baseball experiences a combination of constant horizontal motion (due to inertia) and accelerated downward motion (due to gravity). This is often referred to as projectile motion.

Therefore, the correct answer is B) a combination of constant horizontal motion and accelerated downward motion.

3) The range of a projectile depends on its initial velocity and launch angle. When neglecting air resistance, the maximum range is achieved when the projectile is launched at an angle of 45°.

However, for a given initial speed, the range is symmetric for launch angles of complementary angles. In other words, a launch angle of 30° and a launch angle of 60° will result in the same downrange distance.

Therefore, the correct answer is B) 60°.

4)Once airborne and neglecting air drag, the ball's acceleration is solely due to gravity in the vertical direction.

The acceleration vertically is equal to the acceleration due to gravity (approximately 9.8 m/s²) and is directed downward.

The ball experiences no horizontal acceleration as there is no horizontal force acting on it. Therefore, the vertical acceleration is g downward, and the horizontal acceleration is zero.

5) The baseball has its minimum speed at the highest point of its trajectory. At the highest point, the vertical component of the velocity becomes zero momentarily before changing direction and accelerating downward.

This is because the acceleration due to gravity continuously acts to decrease the vertical velocity until it reaches zero. Therefore, the minimum speed occurs at the highest point of the trajectory.

A diffraction grating has 2100 lines per centimeter. At what angle will the first-order maximum be for 560-nm-wavelength green light?

Answers

The first-order maximum for 560-nm-wavelength green light will occur at an angle of approximately 15.05 degrees.

The angle at which the first-order maximum occurs for green light with a wavelength of 560 nm and a diffraction grating with 2100 lines per centimeter can be calculated using the formula for diffraction. The first-order maximum is given by the equation sin(θ) = λ / (d * m), where θ is the angle, λ is the wavelength, d is the grating spacing, and m is the order of the maximum.

We can use the formula sin(θ) = λ / (d * m), where θ is the angle, λ is the wavelength, d is the grating spacing, and m is the order of the maximum. In this case, we have a diffraction grating with 2100 lines per centimeter, which means that the grating spacing is given by d = 1 / (2100 lines/cm) = 0.000476 cm. The wavelength of green light is 560 nm, or 0.00056 cm.

Plugging these values into the formula and setting m = 1 for the first-order maximum, we can solve for θ: sin(θ) = 0.00056 cm / (0.000476 cm * 1). Taking the inverse sine of both sides, we find that θ ≈ 15.05 degrees. Therefore, the first-order maximum for 560-nm-wavelength green light will occur at an angle of approximately 15.05 degrees.

where:

B is the magnetic field,

μ₀ is the permeability of free space (approximately 4π x 10^-7 T·m/A),

I is the current,

r is the distance between the wires.

I = 8.0 A

r = 3.0 mm = 3.0 x 10⁻³ m

Substituting the values into the formula:

B = (4π x 10⁻⁷ T·m/A × 8.0 A) / (2π × 3.0 x 10⁻³ m)

B = (4π x 10⁻⁷ × 8.0) / (2π × 3.0 x 10⁻³) T

B = 6.67 x 10⁻⁵ T

A levitating train is three cars long (150 m) and has a mass of 100 metric tons (1 metric ton = 1000 kg). The current in the superconducting wires is about 500 kA, and even though the traditional design calls for many small coils of wire, assume for this problem that there is a 150-m-long, straight wire carrying the current beneath the train. A perpendicular magnetic field on the track levitates the train. Find the magnitude of the magnetic field B needed to levitate the train.

Answers

The magnitude of the magnetic field needed to levitate the train is approximately 0.0131 N/(A·m). To find the magnitude of the magnetic field B needed to levitate the train, we can use the equation for the magnetic force on a current-carrying wire. which is given by F = BIL.

The force of attraction between a magnetic field and a current-carrying wire is given by the equation F = BIL, where F is the force, B is the magnetic field, I is the current, and L is the length of the wire. For the train to be levitated, this magnetic force must balance the force of gravity on the train.

The force of gravity on the train can be calculated using the equation F = mg, where m is the mass of the train and g is the acceleration due to gravity. Given that the mass of the train is 100 metric tons, which is equivalent to 100,000 kg, and the acceleration due to gravity is approximately 9.8 m/s², we can determine the force of gravity.

By setting the force of attraction equal to the force of gravity and rearranging the equation, we have BIL = mg. Plugging in the values for the train's length L (150 m), current I (500 kA = 500,000 A), and mass m (100,000 kg), we can solve for the magnetic field B. The magnitude of the magnetic field needed to levitate the train is approximately 0.0131 N/(A·m).

A mass is placed on a frictionless, horizontal table. A spring (k=110 N/m), which can be stretched or compressed, is placed on the table. A 3-kg mass is anchored to the wall. The equilibrium position is marked at zero. A student moves the mass out to x=7.0 cm and releases it from rest. The mass oscillates in simple harmonic motion. Find the position, velocity, and acceleration of the mass at time t=3.00 s.

Answers

Position of the mass after t=3.00 s = 0.0638 m ; Velocity of the mass after t=3.00 s= -0.436 m/s ; Acceleration of the mass after t=3.00 s = -2.98 m/s².

Step 1: Calculate the angular frequencyω = √(k/m), where k is the spring constant and m is the mass.ω = √(110/3)

= 6.83 rad/s

Step 2: Determine the amplitude of oscillation

the displacement equation x(t) = A cos(ωt + φ), where A is the amplitude of oscillation, and φ is the phase constant. x(0) = A cos(φ)

At equilibrium position, x(0) = 0, so A cos(φ) = 0, implying that A = 0 as cos(φ) cannot be zero.

Therefore, the mass does not oscillate at the equilibrium position.

Step 3: Calculate the phase constant φ = cos⁻¹(x(0) / A)

At time t = 0, the mass is at x = 7.0 cm,

sox(0) = 7.0 cm

= 0.07 m

Using x(t) = A cos(ωt + φ),0.07 m

= A cos(φ)cos(φ)

= 0.07/Aφ

= cos⁻¹(0.07/A)

For simplicity, assume that the mass is released from x = 7.0 cm at t = 0 and moves towards the equilibrium position x = 0. Since the phase constant is zero at the equilibrium position, the value of the phase constant is 0 for all subsequent instants.

Step 4: Calculate the position of the mass x(t) = A cos(ωt)

The position of the mass at t = 3.00 s is,

x(3.00 s) = A cos(ωt)

= 0.0638 m.

Step 5: Calculate the velocity of the mass v(t) = -Aω sin(ωt)

The velocity of the mass at t = 3.00 s is,

v(3.00 s) = -0.436 m/s.

Step 6: Calculate the acceleration of the mass

a(t) = -Aω2 cos(ωt)

The acceleration of the mass at t = 3.00 s is,

a(3.00 s) = -2.98 m/s²

Position of the mass after t=3.00 s: x(3.00 s)

= 0.0638 m

Velocity of the mass after t=3.00 s: v(3.00 s)

= -0.436 m/s

Angular frequency (ω) = 3.00 x 10^8 rad/s

Speed of light (c) = 3.00 x 10^8 m/s

The relationship between angular frequency and frequency is ω = 2πf, where f is the frequency.

Since the angular frequency is given, we can convert it to frequency using the formula:

ω = 2πf

f = ω / (2π)

Substituting the values:

f = ([tex]3.00 x 10^8[/tex] rad/s) / (2π)

Now we can calculate the wavelength using the formula:

wavelength = c / f

Substituting the values:

wavelength =[tex](3.00 x 10^8 m/s) / [(3.00 x 10^8[/tex] rad/s) / (2π)]

Simplifying the expression:

wavelength = (2π) / 1

Residents have been instructed to evacuate. Hundreds of thousands of individuals do evacuate, clogging the roadways. Several accidents happen on the evacuation route and many people run out of gas and become stranded. Hundreds of thousands of people decide not to evacuate. The storm hits with high winds and flooding are fierce. In some areas homes are flooded and trees and structures are pushed over by the wind. Many people require rescue, as they wait for days on the roofs of their homes. Others lose their lives. Despite the destruction in some areas, other areas initially expected to be hard hit by the hurricane are minimally impacted. After the storm, those that evacuated cannot return for several days because there is no gas on the return route. They have no idea what they will return to and have no means of protecting their homes from further damage or vandalism.Paragraph 1 = Identify the facts of the scenarioParagraph 2 = Make reasonable inferences given the factsParagraph 3 = Outline any judgements you have made about the scenario.
