The change in gravitational potential energy that the object undergoes if it is released from rest 17.0 m above the ground and ends up 1.30m above the ground is -28,869.5 J.
The change in gravitational potential energy is equal to the product of the object's mass, gravitational acceleration, and the difference in height or altitude (initial and final heights) of the object.
In other words, the formula for gravitational potential energy is given by : ΔPEg = m * g * Δh
where
ΔPEg is the change in gravitational potential energy.
m is the mass of the object.
g is the acceleration due to gravity
Δh is the change in height or altitude
Here, the object has a mass of 2050 kg and is initially at a height of 17.0 m above the ground and then falls to 1.30 m above the ground.
Thus, Δh = 17.0 m - 1.30 m = 15.7 m
ΔPEg = 2050 kg * 9.81 m/s² * 15.7 m
ΔPEg = 319,807.35 J
The object gained 319,807.35 J of gravitational potential energy.
However, the question is asking for the change in gravitational potential energy of the object.
Therefore, the final step is to subtract the final gravitational potential energy from the initial gravitational potential energy.
The final gravitational potential energy can be calculated using the final height of the object.
Final potential energy = m * g * hfinal= 2050 kg * 9.81 m/s² * 1.30 m = 26,618.5 J
Thus, ΔPEg = PEfinal - PEinitial
ΔPEg = 26,618.5 J - 346,487.0 J
ΔPEg = -28,869.5 J
Therefore, the change in gravitational potential energy that the object undergoes is -28,869.5 J.

Two balls, 1 and 2, of equal mass and radius, each rotate around their fixed central axis. If ball 1 rotates with an angular speed equal to three times the angular speed of ball 2, find the ratio KE:/KE,
According to the law of conservation of energy, the sum of kinetic energy and potential energy remains constant for a system. Therefore, any gain or loss in potential energy will lead to an equal and opposite change in kinetic energy. As a result, the total energy of the system is conserved.
Two balls, 1 and 2, of equal mass and radius, each rotate around their fixed central axis. If ball 1 rotates with an angular speed equal to three times the angular speed of ball 2, find the ratio KE:/KE. As given, both balls have the same mass and radius. Therefore, they have the same moment of inertia. The moment of inertia of a sphere rotating about its diameter is given by,I = (2/5) MR²Since both the balls have the same mass and radius, they will have the same moment of inertia.I₁ = I₂ = (2/5) MR².
Now, let the angular speed of ball 2 be ω rad/s. Therefore, the angular speed of ball 1 is 3ω rad/s. Both the balls have the same moment of inertia, so the rotational kinetic energy of each ball will be the same. It is given by,KER = (1/2) I ω²Therefore,KER₁ = KER₂ = (1/2) I ω² = (1/2) (2/5) MR² ω² = (1/5) MR² ω²Now, let's calculate the ratio KE₁ / KE₂.KE₁ / KE₂ = KER₁ / KER₂= [(1/5) MR² ω₁²] / [(1/5) MR² ω₂²]= ω₁² / ω₂²= (3ω₂)² / ω₂²= 9ω₂² / ω₂²= 9/1= 9:1Therefore, the required ratio KE₁ / KE₂ is 9:1.

X Suppose an object is launched from Earth with 0.70 times the escape speed. How many multiples of Earth's radius (Re = 6.37 x 106 m) in radial distance will the object reach before falling back toward Earth? The distances are measured relative to Earth's center, so a ratio of 1.00 would correspond to an object on Earth's surface. For this problem, neglect Earth's rotation and the effect of its atmosphere. For reference, Earth's mass is 5.972 x 1024 kg. Your answer is a ratio and thus unitless:
The object will reach a radial distance of approximately 3.88 times Earth's radius (Re) before falling back toward Earth.
To determine the radial distance the object will reach, we need to compare its kinetic energy (KE) to its gravitational potential energy (PE) at that distance. Given that the object is launched with 0.70 times the escape speed, we can calculate its kinetic energy relative to Earth's surface.
The escape speed (vₑ) can be found using the formula:
vₑ = √((2GM)/Re),
where G is the gravitational constant (approximately 6.674 × 10^(-11) m³/(kg·s²)) and M is Earth's mass (5.972 × 10²⁴ kg).
The object's kinetic energy relative to Earth's surface can be expressed as:
KE = (1/2)mv²,
where m is the object's mass and v is its velocity.
Since the object is launched with 0.70 times the escape speed, its velocity (v₀) can be calculated as:
v₀ = 0.70vₑ.
The kinetic energy of the object at the launch point is equal to its potential energy at a radial distance (r) from Earth's center. Thus, we have:
(1/2)mv₀² = GMm/r.
Simplifying and rearranging the equation gives:
r = (2GM)/(v₀²).
Substituting the value of v₀ in terms of vₑ, we get:
r = (2GM)/(0.70vₑ)².
Now, we can calculate the radial distance (r) in terms of Earth's radius (Re):
r/Re = [(2GM)/(0.70vₑ)²]/Re.
Plugging in the known values, we find:
r/Re ≈ 3.88.
Therefore, the object will reach a radial distance of approximately 3.88 times Earth's radius (Re) before falling back toward Earth.

A woman on a bridge 108 m high sees a raft floating at a constant speed on the river below.She drops a stone from rest in an attempt to hit the raft.The stone is released when the raft has 4.25 m more to travel before passing under the bridge.
The stone hits the water 1.58 m in front of the raft.A formula that can be used here is:
s = ut + 1/2at2
where,
s = distance,
u = initial velocity,
t = time,
a = acceleration.
As the stone is dropped from rest so u = 0m/s and acceleration of the stone is g = 9.8m/s²
We can use the above formula for the stone to find the time it will take to hit the water.
t = √2s/gt
= √(2×108/9.8)t
= √22t
= 4.69s
Now, the time taken by the raft to travel 4.25 m can be found as below:
4.25 = v × 4.69
⇒ v = 4.25/4.69
⇒ v = 0.906 m/s
So, the speed of the raft is 0.906 m/s.An alternative method can be using the following formula:
s = vt
where,
s is the distance travelled,
v is the velocity,
t is the time taken.
For the stone, distance travelled is 108m and the time taken is 4.69s. Thus,
s = vt
⇒ 108 = 4.69v
⇒ v = 108/4.69
⇒ v = 23.01 m/s
Speed of raft is distance travelled by raft/time taken by raft to cover this distance + distance travelled by stone/time taken by stone to cover this distance.The distance travelled by the stone is (108 + 1.58) m, time taken is 4.69s.The distance travelled by the raft is (4.25 + 1.58) m, time taken is 4.69s.
Thus, speed of raft = (4.25 + 1.58)/4.69 m/s
= 1.15 m/s (approx).
Hence, the speed of the raft is 1.15 m/s.

Write a brief explanation (paragraph length) of how changes in
gas pressure relates to your ability to breathe.
List your sources
Changes in gas pressure have a significant impact on breathing. Gas pressure in the lungs must be maintained at a stable level for proper breathing to occur. The muscles in the diaphragm and ribcage work together to change the volume of the chest cavity. When the chest cavity expands, it causes a decrease in pressure that allows air to be drawn into the lungs.
When the chest cavity shrinks, it causes an increase in pressure that forces air out of the lungs. The gas pressure of oxygen and carbon dioxide in the lungs is directly related to the gas pressure in the environment. When the atmospheric pressure is decreased, as occurs at higher altitudes, the pressure of oxygen in the lungs also decreases, making it more difficult to extract oxygen from the air. This makes breathing more difficult. Conversely, when the atmospheric pressure is increased, as occurs in deep sea diving, the pressure of nitrogen in the body increases. This can cause a condition known as decompression sickness or the bends. Nitrogen bubbles can form in the bloodstream, leading to severe pain, organ damage, and even death.

The reduction in intensity for a 1 MHz ultrasound beam traversing 10 cm of tissue with an attenuation coefficient of 0.15 cm^(-1) is 0.2231, or 22.31%.
To calculate the reduction in intensity for a 1 MHz ultrasound beam traversing a thickness (h) of tissue with an attenuation coefficient (α) of 0.15 cm^(-1),
We can use the formula for intensity attenuation in a medium:
I = I0 * e^(-αh)
Where:
I0 is the initial intensity of the ultrasound beam,
I is the final intensity after traversing the tissue,
α is the attenuation coefficient, and
h is the thickness of the tissue.
Given that α = 0.15 cm^(-1) and h = 10 cm, we can substitute these values into the equation:
I = I0 * e^(-0.15 * 10)
Simplifying this equation, we have:
I = I0 * e^(-1.5)
To find the reduction in intensity, we need to calculate the ratio of the final intensity to the initial intensity:
Reduction in intensity = I / I0 = e^(-1.5)
Calculating this value, we find:
Reduction in intensity = 0.2231

Suppose you have two identical particles that attract each other with a certain gravitational force. Now you move them so they are one quarter as far apart as they were originally, but the force between them stays the same. What is one way in which the masses might change so the force could remain constant?
One way to keep the force between two particles constant while reducing their separation by a quarter is by increasing the mass of one particle while decreasing the mass of the other particle in the same proportion.
This adjustment in mass maintains the balance of gravitational forces and allows the force between the particles to remain constant.
According to the law of universal gravitation, the gravitational force between two particles is directly proportional to the product of their masses and inversely proportional to the square of their separation distance. If the separation distance is reduced by a quarter, the force between the particles would increase by a factor of four, assuming the masses remain the same.
To keep the force between the particles constant, the masses can be adjusted accordingly. One way to achieve this is by increasing the mass of one particle by a certain factor while decreasing the mass of the other particle by the same factor.
This adjustment ensures that the product of the masses remains the same, balancing out the increase in force caused by the reduced separation distance.
By carefully adjusting the masses, it is possible to maintain a constant gravitational force between the particles even when the separation distance changes.

The article is located in either the third or fourth quadrant, and its position vector makes an angle of 13.8 degrees clockwise from the positive x-axis.
(a) To find the new position vector of the object, we can use the formula for the circular motion:
x = r cos(theta)
y = r sin(theta)
Given that the radius of the circle is 3.40 m and the object undergoes an angular displacement of 8.85 rad, we can substitute these values into the formulas:
x = (3.40) cos(8.85) ≈ -2.78 m
y = (3.40) sin(8.85) ≈ 0.67 m
Therefore, the new position vector of the object is approximately (-2.78, 0.67) m.
(b) To determine the quadrant in which the particle is located, we need to examine the signs of the x and y components of the position vector. Since the x-coordinate is negative (-2.78 m), the particle is located in either the third or the fourth quadrant.
To find the angle that the position vector makes with the positive x-axis, we can use the arctan function:
angle = arctan(y / x) = arctan(0.67 / -2.78)

A 12.0-watt light bulb uses 43,200 joules of energy per hour. To have that amount of kinetic energy, a 70.0 kg person would have to run at a speed of approximately 1.5 m/s.
Calculating energy usage of a light bulb: The power of the light bulb is given as 12.0 watts, and it is used for one hour. To find the energy used, we multiply the power by the time: Energy = Power x Time. Thus, 12.0 watts x 3600 seconds (1 hour = 3600 seconds) = 43,200 joules of energy.
Determining the required running speed: The kinetic energy of an object is given by the formula KE = (1/2)mv^2, where m is the mass of the object and v is its velocity. Rearranging the formula, we can solve for v: v = sqrt(2KE/m). Plugging in the values, v = sqrt(2 x 43,200 joules / 70.0 kg) ≈ 1.5 m/s. Therefore, a 70.0 kg person would need to run at approximately 1.5 m/s to have the same amount of kinetic energy as the energy used by the light bulb.

filter is the treble control on a stereo, which allows you to adjust the amount of high-frequency sound.As filters are changed, their output signals are altered. In general, as the cutoff frequency is decreased for low-pass filters, the output signal's amplitude is decreased.
The output signal's phase shift is typically more noticeable as the cutoff frequency is lowered in high-pass filters. At higher cutoff frequencies, the amplitude of the output signal for low-pass filters is greater.
As a result, high-pass filters may have a significant impact on high-frequency signals. The cutoff frequency determines the output signal's bandwidth, or the range of frequencies that are allowed to pass through the filter.

For constructive interference to occur, the path length difference between the reflected waves must be an integer multiple of the wavelength. In the case of a thin film, the path length difference is equal to twice the thickness of the film.
The condition for constructive interference in a thin film is given by:
2 * n * t = m * λ
Where:
n is the refractive index of the bubble
t is the thickness of the bubble
m is an integer representing the order of the interference
λ is the wavelength of light
In this case, the refractive index of the bubble is n = 1.34 and the wavelength of the red light is λ = 680 nm.
To find the possible bubble thickness, we need to determine the values of m that satisfy the constructive interference condition. We can start by considering the lowest order of interference, m = 1.
2 * 1.34 * t = 1 * 680 nm
Simplifying the equation, we have:
2.68 * t = 680 nm
t = 680 nm / 2.68
t ≈ 253.73 nm
So, a possible thickness for the bubble to appear reddish is approximately 253.73 nm.
Other possible thicknesses can be found by considering higher orders of interference (m > 1). For example, for m = 2:
2 * 1.34 * t = 2 * 680 nm
Simplifying, we have:
2.68 * t = 1360 nm
t = 1360 nm / 2.68
t ≈ 507.46 nm
Therefore, another possible thickness for the bubble to appear reddish is approximately 507.46 nm.

"A standing wave on a string is described by the wave function
y(x,t) = (3 mm) sin(4πx)cos(30πt). The wave functions of the two
waves that interfere to produce this standing wave pattern are:
The two waves that interfere to produce the standing wave pattern are: y1(x,t) = 1.5 sin(4πx) cos(30πt) and y2(x,t) = 1.5 sin(−4πx) cos(30πt)
Given the wave function of a standing wave on a stringy(x,t) = (3 mm) sin(4πx)cos(30πt)
The general equation for a standing wave is given byy(x,t) = 2A sin(kx) cos(ωt)
where A is the amplitude, k is the wave number, and ω is the angular frequency.
We see that the wave function given can be re-written as
y(x,t) = (3 mm) sin(4πx) cos(30πt)
= 1.5 sin(4πx) [cos(30πt) + cos(−30πt)]
We see that the wave is made up of two waves that have equal amplitudes and frequencies but are traveling in opposite directions, i.e.
ω1 = ω2 = 30π and k1 = −k2 = 4π
So the two waves that interfere to produce the standing wave pattern are: y1(x,t) = 1.5 sin(4πx) cos(30πt) and y2(x,t) = 1.5 sin(−4πx) cos(30πt).

What are the smallest and largest wavelengths of visible light that will also produce interference minima at this location? (Give your answers, in nm, to at least three significant figures. Assume the visible light spectrum ranges from 400 nm to 700 nm.) smallest wavelength x nm largest wavelength nm
In the double-slit experiment with 585 nm light and a 2.00 m distance between slits and screen, the tenth minimum is 8.00 mm away, giving a 1.38 mm slit spacing.
The visible wavelengths producing interference minima are between 138 nm and 1380 nm. (a)
In Young's double-slit experiment, the distance between the slits and the screen is denoted by L, and the distance between the slits is denoted by d. The angle between the central maximum and the nth interference minimum is given by
sin θ = nλ/d,
where λ is the wavelength of the light.
In this case, the tenth interference minimum is observed, which means n = 10. The wavelength of the light is given as 585 nm. The distance between the slits and the screen is 2.00 m, or 2000 mm. The distance from the central maximum to the tenth minimum is 8.00 mm.
Using the above equation, we can solve for the slit spacing d:
d = nλL/sin θ
First, we need to find the angle θ corresponding to the tenth minimum:
sin θ = (nλ)/d = (10)(585 nm)/d
θ = sin^(-1)((10)(585 nm)/d)
Now we can substitute this into the equation for d:
d = (nλL)/sin θ = (10)(585 nm)(2000 mm)/sin θ = 1.38 mm
Therefore, the slit spacing is 1.38 mm.
(b)
The condition for the nth interference minimum is given by
sin θ = nλ/d
For the tenth minimum, n = 10 and d = 1.38 mm. To find the smallest and largest wavelengths of visible light that will also produce interference minima at this location, we need to find the values of λ that satisfy this condition for n = 10 and d = 1.38 mm.
For the smallest wavelength, we need to find the maximum value of sin θ that satisfies the above condition. This occurs when sin θ = 1, which gives
λ_min = d/n = 1.38 mm/10 = 0.138 mm = 138 nm
For the largest wavelength, we need to find the minimum value of sin θ that satisfies the above condition. This occurs when sin θ = 0, which gives
λ_max = d/n = 1.38 mm/10 = 0.138 mm = 1380 nm
Therefore, the smallest wavelength of visible light that will produce interference minima at this location is 138 nm, and the largest wavelength is 1380 nm.

h is the depth of the swimmer below the surface of the fluid
Given values:
ρ (density of water) = 1000 kg/m³
g (acceleration due to gravity) ≈ 9.8 m/s²
h (depth below the surface) = 4 m
Substituting the values into the formula:
P = 1000 kg/m³ × 9.8 m/s² × 4 m
= 39,200 Pa
B) To calculate the pressure when the person is in the airplane 1,500 m in the air, one need to consider the atmospheric pressure and the differnce in height.
The atmospheric pressure is given as 1.01 x 1[tex]0^5[/tex] Pa.
Since the person is in the air, one can assume that the density of air remains constant throughout the calculation.
Using the formula for pressure difference due to height:

ρ (density of air) = 1.29 kg/m³
g (acceleration due to gravity) ≈ 9.8 m/s²
Δh is the difference in height
Given values:
ρ (density of air) = 1.29 kg/m³
g (acceleration due to gravity) ≈ 9.8 m/s²
Δh (difference in height) = 1500 m
Substituting the values into the formula:
ΔP = 1.29 kg/m³ × 9.8 m/s² × 1500 m
≈ 18,987 Pa
To find the total pressure,
P = Atmospheric pressure + ΔP

The electric force between two point charges, one with a charge of -4.0 μC and the other with a charge of 92-8.0 µC, separated by a distance of 4.0 cm, is approximately 31.5 N according to Coulomb's law. The force is attractive due to the opposite signs of the charges.
To calculate the electric force between two point charges, we can use Coulomb's law, which states that the electric force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The formula for the electric force (F) between two charges (q1 and q2) separated by a distance (r) is given by:
F = k * (|q1| * |q2|) / r^2
Where:
F is the electric force
k is the electrostatic constant, approximately equal to 9 x 10^9 Nm²/C²
q1 and q2 are the magnitudes of the charges
Given:
q1 = -4.0 μC (microCoulombs)
q2 = 92-8.0 µC (microCoulombs)
r = 4.0 cm = 0.04 m
k = 9 x 10^9 Nm²/C²
Let's calculate the electric force using the given values:
F = (9 x 10^9 Nm²/C²) * (|-4.0 μC| * |92-8.0 µC|) / (0.04 m)^2
First, let's convert the charges to Coulombs:
1 μC (microCoulomb) = 1 x 10^-6 C (Coulomb)
1 µC (microCoulomb) = 1 x 10^-6 C (Coulomb)
q1 = -4.0 μC = -4.0 x 10^-6 C
q2 = 92-8.0 µC = 92-8.0 x 10^-6 C
Now we can substitute the values into the formula:
F = (9 x 10^9 Nm²/C²) * (|-4.0 x 10^-6 C| * |92-8.0 x 10^-6 C|) / (0.04 m)^2
Calculating the magnitudes of the charges:
|q1| = |-4.0 x 10^-6 C| = 4.0 x 10^-6 C
|q2| = |92-8.0 x 10^-6 C| = 92-8.0 x 10^-6 C
Substituting the values:
F = (9 x 10^9 Nm²/C²) * (4.0 x 10^-6 C) * (92-8.0 x 10^-6 C) / (0.04 m)^2
Now let's calculate the force:
F = (9 x 10^9 Nm²/C²) * (4.0 x 10^-6 C) * (92-8.0 x 10^-6 C) / (0.04 m)^2
F = (9 x 10^9) * (4.0 x 10^-6) * (92-8.0 x 10^-6) / 0.0016
F ≈ 31.5 N
Therefore, the electric force between the two point charges is approximately 31.5 N, and it is attractive since the charges have opposite signs.

The way two light sources interact to produce interference
patterns.
The absorption of one compon
Diffraction refers to the behavior of waves, including light waves, when they encounter obstacles or pass through small openings. It involves the bending and spreading of waves as they pass around the edges of an obstacle or through a narrow opening.
So, out of the options given, the correct statement is: "Diffraction is the way light behaves when it goes through a narrow opening."
The diffraction of light through a narrow opening leads to the formation of a pattern of alternating light and dark regions called a diffraction pattern or diffraction fringes. These fringes can be observed on a screen placed behind the opening or obstacle. The pattern arises due to the constructive and destructive interference of the diffracted waves as they interact with each other.
It's important to note that while interference is involved in the formation of diffraction patterns, diffraction itself refers specifically to the bending and spreading of waves as they encounter obstacles or narrow openings. Interference, on the other hand, refers to the interaction of multiple waves, such as from two light sources, leading to the formation of interference patterns.

In general, how does changing the pressure acting on a
material effect the temperature required for a phase change (i.e.
the boiling temperature of water)
Changing the pressure acting on a material affects the temperature required for a phase change (i.e., the boiling temperature of water) in a general way. The following is an explanation of the connection between pressure and phase change:
Pressure is defined as the force that a gas or liquid exerts per unit area of the surface that it is in contact with. The boiling point of a substance is defined as the temperature at which the substance changes phase from a liquid to a gas or a vapor. There is a connection between pressure and the boiling temperature of water. When the pressure on a liquid increases, the boiling temperature of the liquid also increases. This is due to the fact that boiling occurs when the vapor pressure of the liquid equals the pressure of the atmosphere.
When the pressure is increased, the vapor pressure must also increase to reach the pressure of the atmosphere. As a result, more energy is required to cause the phase change, and the boiling temperature rises as a result.
As a result, the boiling temperature of water rises as the pressure on it increases. When the pressure is decreased, the boiling temperature of the liquid decreases as well.

The phenomenon described, where an object returns to its original size and shape after the removal of a distorting force, is known as elastic deformation.
Elastic deformation refers to the reversible change in the shape or size of an object under the influence of an external force. When a distorting force is applied to an object, it causes the object to deform. However, if the force is within the elastic limit of the material, the deformation is temporary and the object retains its ability to return to its original shape and size once the force is removed.
This behavior is characteristic of materials with elastic properties, such as metals, rubber, and certain plastics. Within the elastic limit, these materials exhibit a linear relationship between the applied force and the resulting deformation.
This means that the deformation is directly proportional to the force applied. When the force is removed, the object undergoes elastic recoil and returns to its original configuration due to the inherent elastic forces within the material.

A particular human hair has a Young's modulus of 3.17 x 10° N/m² and a diameter of 147 µm. If a 248 g object is suspended by the single strand of hair that is originally 17.0 cm long, by how much ΔL hair will the hair stretch? If the same object were hung from an aluminum wire of the same dimensions as the hair, by how much ΔL AI would the aluminum stretch? If the strand of hair is modeled as a spring, what is its spring constant Khair?
The hair will stretch by approximately 2.08 mm (ΔLhair) when a 248 g object is suspended from it. The spring constant of the hair, Khair, is calculated to be approximately 14.96 N/m.
If the same object were hung from an aluminum wire with the same dimensions as the hair, the aluminum would stretch by approximately 0.043 mm (ΔLAI).
To calculate the stretch in the hair (ΔLhair), we can use Hooke's law, which states that the amount of stretch in a material is directly proportional to the applied force.
The formula for calculating the stretch is ΔL = F * L / (A * E), where F is the force applied, L is the original length of the material, A is the cross-sectional area, and E is the Young's modulus.
Given that the diameter of the hair is 147 µm, we can calculate the cross-sectional area (A) using the formula A = π * [tex](d/2)^2[/tex], where d is the diameter. Plugging in the values, we find A = 2.67 x [tex]10^{-8}[/tex] m².
Now, let's calculate the stretch in the hair (ΔLhair). The force applied is the weight of the object, which is given as 248 g. Converting it to kilograms, we have F = 0.248 kg * 9.8 m/s² = 2.43 N.
Substituting the values into the formula, we get ΔLhair = (2.43 N * 0.17 m) / (2.67 x [tex]10^{-8}[/tex] m² * 3.17 x [tex]10^{10}[/tex] N/m²) ≈ 2.08 mm.
For the aluminum wire, we use the same formula with its own Young's modulus. Let's assume that the Young's modulus of aluminum is 7.0 x [tex]10^{10}[/tex] N/m². Using the given values, we find ΔLAI = (2.43 N * 0.17 m) / (2.67 x [tex]10^{-8}[/tex] m² * 7.0 x [tex]10^{10}[/tex] N/m²) ≈ 0.043 mm.
Finally, the spring constant of the hair (Khair) can be calculated using Hooke's law formula, F = k * ΔLhair. Rearranging the formula, we have k = F / ΔLhair = 2.43 N / 0.00208 m = 14.96 N/m.
