The magnetic force on a straight wire 0.30 m long is 2.6 x 10^-3 N. The current in the wire is 15.0 A. What is the magnitude of the magnetic field that is perpendicular to the wire?

The Magnetic Force On A Straight Wire 0.30 M Long Is 2.6 X 10^-3 N. The Current In The Wire Is 15.0 A.

Answers

Answer 1

Answer:  the magnitude of the magnetic field perpendicular to the wire is approximately 1.93 x 10^-3 T.

Explanation:

The magnetic force on a straight wire carrying current is given by the formula:

F = B * I * L * sin(theta),

where F is the magnetic force, B is the magnetic field, I is the current, L is the length of the wire, and theta is the angle between the magnetic field and the wire (which is 90 degrees in this case since the field is perpendicular to the wire).

Given:

Length of the wire (L) = 0.30 m

Current (I) = 15.0 A

Magnetic force (F) = 2.6 x 10^-3 N

Theta (angle) = 90 degrees

We can rearrange the formula to solve for the magnetic field (B):

B = F / (I * L * sin(theta))

Plugging in the given values:

B = (2.6 x 10^-3 N) / (15.0 A * 0.30 m * sin(90 degrees))

Since sin(90 degrees) equals 1:

B = (2.6 x 10^-3 N) / (15.0 A * 0.30 m * 1)

B = 2.6 x 10^-3 N / (4.5 A * 0.30 m)

B = 2.6 x 10^-3 N / 1.35 A*m

B ≈ 1.93 x 10^-3 T (Tesla)

Answer the following - show your work! (5 marks): Maximum bending moment: A simply supported rectangular beam that is 3000 mm long supports a point load (P) of 5000 N at midspan (center). Assume that the dimensions of the beams are as follows: b= 127 mm and h = 254 mm, d=254mm. What is the maximum bending moment developed in the beam? What is the overall stress? f = Mmax (h/2)/bd3/12 Mmax = PL/4

Answers

The maximum bending moment developed in the beam is 3750000 N-mm. The overall stress is 4.84 MPa.

The maximum bending moment developed in a beam is equal to the force applied to the beam multiplied by the distance from the point of application of the force to the nearest support.

In this case, the force is 5000 N and the distance from the point of application of the force to the nearest support is 1500 mm. Therefore, the maximum bending moment is:

Mmax = PL/4 = 5000 N * 1500 mm / 4 = 3750000 N-mm

The overall stress is equal to the maximum bending moment divided by the moment of inertia of the beam cross-section. The moment of inertia of the beam cross-section is calculated using the following formula:

I = b * h^3 / 12

where:

b is the width of the beam in mm

h is the height of the beam in mm

In this case, the width of the beam is 127 mm and the height of the beam is 254 mm. Therefore, the moment of inertia is:

I = 127 mm * 254 mm^3 / 12 = 4562517 mm^4

Plugging in the known values, we get the following overall stress:

f = Mmax (h/2) / I = 3750000 N-mm * (254 mm / 2) / 4562517 mm^4 = 4.84 MPa

A laser beam is normally incident on a single slit with width 0.630 mm. A diffraction pattern forms on a screen a distance 1.20 m beyond the slit. The width of the central maximum is 2.38 mm. Calculate the wavelength of the light (in nm).

Answers

"The wavelength of the light is approximately 1.254 nm." The wavelength of light refers to the distance between successive peaks or troughs of a light wave. It is a fundamental property of light and determines its color or frequency. Wavelength is typically denoted by the symbol λ (lambda) and is measured in meters (m).

To calculate the wavelength of the light, we can use the formula for the width of the central maximum in a single slit diffraction pattern:

w = (λ * L) / w

Where:

w is the width of the central maximum (2.38 mm = 0.00238 m)

λ is the wavelength of the light (to be determined)

L is the distance between the slit and the screen (1.20 m)

w is the width of the slit (0.630 mm = 0.000630 m)

Rearranging the formula, we can solve for the wavelength:

λ = (w * w) / L

Substituting the given values:

λ = (0.000630 m * 0.00238 m) / 1.20 m

Calculating this expression:

λ ≈ 1.254e-6 m

To convert this value to nanometers, we multiply by 10^9:

λ ≈ 1.254 nm

Therefore, the wavelength of the light is approximately 1.254 nm.

Answers

The kinetic energy at one-third of the maximum velocity is KE = (1/9)(6 J) = 0.67 J, rounded to the hundredth place.

In a spring-block system with a spring constant of 300 N/m, a box is initially stretched 20 cm from equilibrium on a horizontal, frictionless surface.

The box is released at t = 0 s. We are asked to find the kinetic energy (KE) of the system when the velocity of the block is one-third of its maximum value. The answer will be provided in joules (J) rounded to the hundredth place.

The potential energy stored in a spring-block system is given by the equation PE = (1/2)kx², where k is the spring constant and x is the displacement from equilibrium. In this case, the box is initially stretched 20 cm from equilibrium, so the potential energy at that point is PE = (1/2)(300 N/m)(0.20 m)² = 6 J.

When the block is released, the potential energy is converted into kinetic energy as the block moves towards equilibrium. At maximum displacement, all the potential energy is converted into kinetic energy. Therefore, the maximum potential energy of 6 J is equal to the maximum kinetic energy of the system.

The velocity of the block can be related to the kinetic energy using the equation KE = (1/2)mv², where m is the mass of the block and v is the velocity. Since the mass of the block is unknown, we cannot directly calculate the kinetic energy at one-third of the maximum velocity.

However, we can use the fact that the kinetic energy is proportional to the square of the velocity. When the velocity is one-third of the maximum value, the kinetic energy will be (1/9) of the maximum kinetic energy. Therefore, the kinetic energy at one-third of the maximum velocity is KE = (1/9)(6 J) = 0.67 J, rounded to the hundredth place.

When one person shouts at a football game, the sound intensity level at the center of the field is 60.8 dB. When all the people shout together, the intensity level increases to 88.1 dB. Assuming that each person generates the same sound intensity at the center of the field, how many people are at the game?

Answers

Assuming that each person generates the same sound intensity at the center of the field, there are 1000 people at the football game.

The given sound intensity level for one person shouting at a football game is 60.8 dB and for all the people shouting together, the intensity level is 88.1 dB.

Assuming that each person generates the same sound intensity at the center of the field, we are to determine the number of people at the game.

I = P/A, where I is sound intensity, P is power and A is area of sound waves.

From the definition of sound intensity level, we know that

β = 10log(I/I₀), where β is the sound intensity level and I₀ is the threshold of hearing or 1 × 10^(-12) W/m².

Rewriting the above equation for I, we get,

I = I₀ 10^(β/10)

Here, sound intensity level when one person is shouting (β₁) is given as 60.8 dB.

Therefore, sound intensity (I₁) of one person shouting can be calculated as:

I₁ = I₀ 10^(β₁/10)I₁ = 1 × 10^(-12) × 10^(60.8/10)I₁ = 10^(-6) W/m²

Now, sound intensity level when all the people are shouting (β₂) is given as 88.1 dB.

Therefore, sound intensity (I₂) when all the people shout together can be calculated as:

I₂ = I₀ 10^(β₂/10)I₂ = 1 × 10^(-12) × 10^(88.1/10)I₂ = 10^(-3) W/m²

Let's assume that there are 'n' number of people at the game.

Therefore, sound intensity (I) when 'n' people are shouting can be calculated as:

I = n × I₁

Here, we have sound intensity when all the people are shouting,

I₂ = n × I₁n = I₂/I₁n = (10^(-3))/(10^(-6))n = 1000

Hence, there are 1000 people at the football game.

V =

Answers

The electric potential at a point halfway between the 35.0 nC charge at the origin and the 57.0 nC charge on the +x-axis is 1.83 kV.

To calculate the electric potential at a point halfway between the two charges, we need to consider the contributions from each charge and sum them together.

Given:

Charge q1 = 35.0 nC at the origin (0, 0).

Charge q2 = 57.0 nC on the +x-axis, 2.20 cm from the origin.

The electric potential due to a point charge at a distance r is given by the formula:

V = k * (q / r),

where V is the electric potential, k is the electrostatic constant (k = 8.99 x 10^9 N m^2/C^2), q is the charge, and r is the distance.

Let's calculate the electric potential due to each charge:

For q1 at the origin (0, 0):

V1 = k * (q1 / r1),

where r1 is the distance from the point halfway between the charges to the origin (0, 0).

For q2 on the +x-axis, 2.20 cm from the origin:

V2 = k * (q2 / r2),

where r2 is the distance from the point halfway between the charges to the charge q2.

Since the point halfway between the charges is equidistant from each charge, r1 = r2.

Now, let's calculate the distances:

r1 = r2 = 2.20 cm / 2 = 1.10 cm = 0.0110 m.

Substituting the values into the formula:

V1 = k * (35.0 x 10^(-9) C) / (0.0110 m),

V2 = k * (57.0 x 10^(-9) C) / (0.0110 m).

Calculating the electric potentials:

V1 ≈ 2863.64 V,

V2 ≈ 4660.18 V.

To find the electric potential at the point halfway between the charges, we need to sum the contributions from each charge:

V = V1 + V2.

Substituting the calculated values:

V ≈ 2863.64 V + 4660.18 V.

Calculating the sum:

V ≈ 7523.82 V.

Therefore, the electric potential at a point halfway between the two charges is approximately 7523.82 volts.

An RLC series circuit has a 1.00 kΩ resistor, a 130 mH inductor, and a 25.0 nF capacitor.(a)The circuit's impedance at 490 Hz is approximately 1013.53 Ω.(b)The circuit's impedance at 7.50 kHz is approximately 6137.02 Ω.

(a) To find the circuit's impedance at 490 Hz, we can use the formula:

Z = √(R^2 + (XL - XC)^2)

where Z is the impedance, R is the resistance, XL is the inductive reactance, and XC is the capacitive reactance.

Given:

R = 1.00 kΩ = 1000 Ω

L = 130 mH = 0.130 H

C = 25.0 nF = 25.0 × 10^(-9) F

f = 490 Hz

First, we need to calculate the inductive reactance (XL) and capacitive reactance (XC):

XL = 2πfL

= 2π × 490 × 0.130

≈ 402.12 Ω

XC = 1 / (2πfC)

= 1 / (2π × 490 × 25.0 × 10^(-9))

≈ 129.01 Ω

Now we can calculate the impedance:

Z = √(R^2 + (XL - XC)^2)

= √((1000)^2 + (402.12 - 129.01)^2)

≈ √(1000000 + 27325.92)

≈ √1027325.92

≈ 1013.53 Ω

Therefore, the circuit's impedance at 490 Hz is approximately 1013.53 Ω.

(b) To find the circuit's impedance at 7.50 kHz, we can use the same formula as before:

Z = √(R^2 + (XL - XC)^2)

Given:

f = 7.50 kHz = 7500 Hz

First, we need to calculate the inductive reactance (XL) and capacitive reactance (XC) at this frequency:

XL = 2πfL

= 2π × 7500 × 0.130

≈ 6069.08 Ω

XC = 1 / (2πfC)

= 1 / (2π × 7500 × 25.0 × 10^(-9))

≈ 212.13 Ω

Now we can calculate the impedance:

Z = √(R^2 + (XL - XC)^2)

= √((1000)^2 + (6069.08 - 212.13)^2)

≈ √(1000000 + 36622867.96)

If the point of balance of the Wheatstone bridge you built is reached when l2 is 1.8 cm , calculate the experimental value for Rx. Give your answer in units of Ohms with 1 decimal.

Answers

In the circuit given in Figure 3-2 of your lab instructions with slide wire of total length 7.7cm, we need to experimentally determine the value of the unknown resistance Rx where Rc is 7.3.

If the point of balance of the Wheatstone bridge we built is reached when l2 is 1.8 cm, we have to calculate the experimental value for Rx.

The Wheatstone bridge circuit shown in Figure 3-2 is balanced when the potential difference across point B and D is zero.

This happens when R1/R2 = Rx/R3. Thus, the resistance Rx can be determined as:

Rx = (R1/R2) * R3, where R1, R2, and R3 are the resistances of the resistor in the circuit.

To find R2, we use the slide wire of total length 7.7 cm. We can say that the resistance of the slide wire is proportional to its length.

Thus, the resistance of wire of length l1 would be (R1 / 7.7) l1, and the resistance of wire of length l2 would be (R2 / 7.7) l2.

Using these formulas, the value of R2 can be calculated:

R1 / R2 = (l1 - l2) / l2 => R2

= R1 * l2 / (l1 - l2)

= 3.3 * 1.8 / (7.7 - 1.8)

= 0.905 Ω.

Now that we know the value of R2, we can calculate the value of Rx:Rx = (R1 / R2) * R3 = (3.3 / 0.905) * 7.3 = 26.68 Ω

Therefore, the experimental value for Rx is 26.7 Ω.

Diamagnets have the property that they "dampen" the effects of an external magnetic field by creating an opposing magnetic field. The diamagnet thus has an induced dipole moment that is anti-aligned, such that the induced north pole is closer to the north pole creating the external field. An application of this is that diamagnets can be levitated (Links to an external site.).
Now, the mathematics of generally describing a force by a non-uniform field on a dipole is a little beyond the scope of this course, but we can still work through an approximation based on energy. Essentially, whenever the theoretical loss of gravitational potential energy from "falling" no longer can "pay the cost" of increasing the magnetic potential energy, the object no longer wants to fall.
Suppose a diamagnetic object floats above the levitator where the magnitude of the magnetic field is 18 T, which is inducing* a magnetic dipole moment of 3.2 μA⋅m2 in the object. The magnetic field 2.0 mm below the object is stronger with a magnitude of 33 T. What is the approximate mass of the floating object?
Give your answer in units of g (i.e., x10-3 kg), and use g = 9.81 m/s2. You may assume the object's size is negligible.

Answers

The approximate mass of the floating object is approximately 37.99 grams.

To solve this problem, we can use the concept of potential energy. When the diamagnetic object floats above the levitator, the gravitational potential energy is balanced by the increase in magnetic potential energy.

The gravitational potential energy is by the formula:

[tex]PE_gravity = m * g * h[/tex]

where m is the mass of the object, g is the acceleration due to gravity, and h is the height from the reference point (levitator) to the object.

The magnetic potential energy is by the formula:

[tex]PE_magnetic = -μ • B[/tex]

where μ is the magnetic dipole moment and B is the magnetic field.

In equilibrium, the gravitational potential energy is equal to the magnetic potential energy:

[tex]m * g * h = -μ • B[/tex]

We can rearrange the equation to solve for the mass of the object:

[tex]m = (-μ • B) / (g • h)[/tex]

Magnetic dipole moment [tex](μ) = 3.2 μA⋅m² = 3.2 x 10^(-6) A⋅m²[/tex]

Magnetic field above the object (B1) = 18 T

Magnetic field below the object (B2) = 33 T

Height (h) =[tex]2.0 mm = 2.0 x 10^(-3) m[/tex]

Acceleration due to gravity (g) = 9.81 m/s²

Using the values provided, we can calculate the mass of the floating object:

[tex]m = [(-3.2 x 10^(-6) A⋅m²) • (18 T)] / [(9.81 m/s²) • (2.0 x 10^(-3) m)][/tex]

m = -0.03799 kg

To convert the mass to grams, we multiply by 1000:

[tex]m = -0.03799 kg * 1000 = -37.99 g[/tex]

Since mass cannot be negative, we take the absolute value:

m ≈ 37.99 g

Therefore, the approximate mass of the floating object is approximately 37.99 grams.

a. Wavefunction: The wave function for the n=5 state of the Simple Harmonic Oscillator (SHO) can be represented by a Gaussian-shaped curve centered at the equilibrium position. The amplitude of the curve decreases as you move away from the equilibrium position. The sketch should show a symmetric curve with a maximum at the equilibrium position and decreasing amplitudes as you move towards the extremes.

b. Probabilities: The probability of finding the state as a function of interatomic separation for the n=5 state of the SHO can be depicted as a plot with the probability density on the y-axis and the interatomic separation on the x-axis. The sketch should show a peak at the equilibrium position and decreasing probabilities as you move away from the equilibrium. The important feature to highlight is that the probability distribution extends beyond the equilibrium position, indicating the possibility of finding the molecule at larger interatomic separations.

c. Classical turning points: In the classical description of the Simple Harmonic Oscillator, the turning points occur when the total energy of the system equals the potential energy. For the n=1 state, the probability of the interatomic distance being outside the classically allowed region is negligible. The classical turning points are close to the equilibrium position, and the probability of finding the molecule significantly drops as you move away from the equilibrium.

The thicker the PZT element, the ______ the frequency.

Answers

The statement, "The thicker the PZT element, the lower the frequency," is the appropriate answer. We know that a PZT element is a piezoelectric element that functions as a sensor or actuator.

The thickness of the PZT element can influence its properties.PZT, or lead zirconate titanate, is a piezoelectric ceramic that has a wide variety of applications, including inkjet printers and loudspeakers. PZT is composed of lead, zirconium, and titanium oxide and is a crystalline solid.

The piezoelectric effect causes PZT to produce a voltage proportional to the mechanical strain that is placed on it. It also generates mechanical strain when an electric field is applied to it. The thickness of the PZT element has a big impact on its properties. PZT's frequency is affected by its thickness, among other things. The thicker the PZT element, the lower the frequency.

Co connot be founds
D• is the change in momentur over the time interval.

Answers

In the case of a time-varying force (ie. not constant), is the change in momentum over the time interval. The correct option is D.

The assertion that "A is the area under the force vs. time curve" is false. The impulse, not the work, is represented by the area under the force vs. time curve.

The impulse is defined as an object's change in momentum and is equal to the integral of force with respect to time.

The statement "B is the average force during the time interval" is false. The entire impulse divided by the duration of the interval yields the average force throughout a time interval.

The assertion "C cannot be found" is false. Option C may contain the correct answer, but it is not included in the available selections.

Thus, the correct option is D.

for a particle inside 4 2. plot the wave function and energy infinite Square well.

Answers

The procedures below may be used to draw the wave function and energy infinite square well for a particle inside 4 2.To plot the wave function and energy infinite square well for a particle inside 4 2, follow these steps:

Step 1: Determine the dimensions of the well .The infinite square well has an infinitely high potential barrier at the edges and a finite width. The dimensions of the well must be known to solve the Schrödinger equation.

In this problem, the well is from x = 0 to x = L.

Let's define the boundaries of the well: L = 4.2.

Step 2: Solve the time-independent Schrödinger equation .The next step is to solve the time-independent Schrödinger equation, which is given as:

Hψ(x) = Eψ(x)

where ,

H is the Hamiltonian operator,

ψ(x) is the wave function,

E is the total energy of the particle

x is the position of the particle inside the well.

The Hamiltonian operator for a particle inside an infinite square well is given as:

H = -h²/8π²m d²/dx²

where,

h is Planck's constant,

m is the mass of the particle

d²/dx² is the second derivative with respect to x.

To solve the Schrödinger equation, we assume a wave function, ψ(x), of the form:

ψ(x) = Asin(kx) .

The wave function must be normalized, so:

∫|ψ(x)|²dx = 1

where,

A is a normalization constant.

The energy of the particle is given by:

E = h²k²/8π²m

Substituting the wave function and the Hamiltonian operator into the Schrödinger equation,

we get: -

h²/8π²m d²/dx² Asin(kx) = h²k²/8π²m Asin(kx)

Rearranging and simplifying,

we get:

d²/dx² Asin(kx) + k²Asin(kx) = 0

Dividing by Asin(kx),

we get:

d²/dx² + k² = 0

Solving this differential equation gives:

ψ(x) = Asin(nπx/L)

E = (n²h²π²)/(2mL²)

where n is a positive integer.

The normalization constant, A, is given by:

A = √(2/L)

Step 3: Plot the wave function . The wave function for the particle inside an infinite square well can be plotted using the formula:

ψ(x) = Asin(nπx/L)

The first three wave functions are shown below:

ψ₁(x) = √(2/L)sin(πx/L)ψ₂(x)

= √(2/L)sin(2πx/L)ψ₃(x)

= √(2/L)sin(3πx/L)

Step 4: Plot the energy levels .The energy levels for a particle inside an infinite square well are given by:

E = (n²h²π²)/(2mL²)

The energy levels are quantized and can only take on certain values.

The first three energy levels are shown below:

E₁ = (h²π²)/(8mL²)

E₂ = (4h²π²)/(8mL²)

E₃ = (9h²π²)/(8mL²)

A diatomic ideal gas occupies 4.0 L and pressure of 100kPa. It is compressed adiabatically to 1/4th its original volume, then cooled at constant volume back to its original temperature. Finally, it is allowed to isothermally expand back to
its original volume.
A. Draw a PV diagram B. Find the Heat, Work, and Change in Energy for each process (Fill in Table). Do not assume anything about the net values to fill in the
values for a process.
C. What is net heat and work done?

Answers

A)Draw a PV diagram

PV diagram is drawn by considering its constituent processes i.e. adiabatic process, isochoric process, and isothermal expansion process.

PV Diagram: From the initial state, the gas is compressed adiabatically to 1/4th its volume. This is a curve process and occurs without heat exchange. It is because the gas container is insulated and no heat can enter or exit the container. The second process is cooling at a constant volume. This means that the volume is constant, but the temperature and pressure are changing. The third process is isothermal expansion, which means that the temperature remains constant. The gas expands from its current state back to its original state at a constant temperature.

B) Find the Heat, Work, and Change in Energy for each process

Heat for Adiabatic Compression, Cooling at constant volume, Isothermal Expansion  will be 0, -9600J, 9600J respectively. work will be -7200J, 0J, 7200J respectively. Change in Energy will be -7200J, -9600J, 2400J.

The Heat, Work and Change in Energy are shown in the table below:

Process                                       Heat      Work         Change in Energy

Adiabatic Compression                0         -7200 J          -7200 J

Cooling at constant volume     -9600 J      0                 -9600 J

Isothermal Expansion               9600 J    7200 J           2400 J

Net Work Done = Work Done in Adiabatic Compression + Work Done in Isothermal Expansion= 7200 J + (-7200 J) = 0

Net Heat = Heat Absorbed during Cooling at Constant Volume + Heat Released during Isothermal Expansion= -9600 J + 9600 J = 0

C) What is net heat and work done?

The net heat and work done are both zero.

Net Work Done = Work Done in Adiabatic Compression + Work Done in Isothermal Expansion = 0

Net Heat = Heat Absorbed during Cooling at Constant Volume + Heat Released during Isothermal Expansion = 0

Therefore, the net heat and work done are both zero.

Determine the Schwartzschild radius of a black hole equal to the mass of the entire Milky Way galaxy (1.1 X 1011 times the mass of the Sun).

Answers

The Schwarzschild radius of a black hole with a mass equal to the mass of the entire Milky Way galaxy is approximately 3.22 × 10^19 meters.

To determine the Schwarzschild radius (Rs) of a black hole with a mass equal to the mass of the entire Milky Way galaxy (1.1 × 10^11 times the mass of the Sun), we can use the formula:

Rs = (2 * G * M) / c^2,

where:

Rs is the Schwarzschild radius,G is the gravitational constant (6.67 × 10^-11 N m^2/kg^2),M is the mass of the black hole, andc is the speed of light (3.00 × 10^8 m/s).

Let's calculate the Schwarzschild radius using the given mass:

M = 1.1 × 10^11 times the mass of the Sun = 1.1 × 10^11 * (1.99 × 10^30 kg).

Rs = (2 * 6.67 × 10^-11 N m^2/kg^2 * 1.1 × 10^11 * (1.99 × 10^30 kg)) / (3.00 × 10^8 m/s)^2.

Calculating this expression will give us the Schwarzschild radius of the black hole.

Rs ≈ 3.22 × 10^19 meters.

Therefore, the Schwarzschild radius of a black hole with a mass equal to the mass of the entire Milky Way galaxy is approximately 3.22 × 10^19 meters.

Diamagnets have the property that they "dampen" the effects of an external magnetic field by creating an opposing magnetic field. The diamagnet thus has an induced dipole moment that is anti-aligned, such that the induced north pole is closer to the north pole creating the external field. An application of this is that diamagnets can be levitated (Links to an external site.).Now, the mathematics of generally describing a force by a non-uniform field on a dipole is a little beyond the scope of this course, but we can still work through an approximation based on energy.

Can threats to people's social (i.e. group) identity lead to deviant attitudes and behaviors? Belmi et al. (2015) sought to answer this question. They had 188 self-identified Black American college students and 123 self-identified White American college students complete three sets of self-reported measures. The first set asked whether the student worried about being seen negatively in school because of their ethnicity. The second set asked whether the student felt and expected to be disrespected at school. The final set asked whether the student engaged in delinquent behaviors at school in the past year (e.g. cheating on a test, copying someone else's work, picking a fight, using drugs, etc.). As predicted, the authors found that the more students worried about being seen negatively in school because of their ethnicity, the more likely they were to engage in social deviance, though this relationship occurred only for Black American students.
