To obtain the numerical values, we need to know the charge transferred from one sphere to the other and the distance between the spheres
(a) To determine the magnitude of the electrostatic force acting on each sphere, we can use Coulomb's law. Coulomb's law states that the magnitude of the electrostatic force between two charged objects is given by:
F = k * (|q1| * |q2|) / r²
where F is the electrostatic force, k is the electrostatic constant (k ≈ 8.99 × 10^9 N m²/C²), |q1| and |q2| are the magnitudes of the charges on the spheres, and r is the distance between the centers of the spheres.
In this case, both spheres have the same magnitude of charge since 9.88 × 10^13 electrons were transferred from one sphere to the other. The charge of one electron is approximately 1.6 × 10^(-19) C. Therefore, each sphere will have a charge of:
|q1| = |q2| = (9.88 × 10^13) * (1.6 × 10^(-19)) C
Substituting the values into Coulomb's law equation and using the given distance of 0.659 m, we can calculate the magnitude of the electrostatic force.
(b) The force between the spheres can be attractive or repulsive, depending on the sign of the charges. Since electrons were transferred from one sphere to the other, the sphere that gained the electrons will have a negative charge, and the sphere that lost the electrons will have a positive charge.
Like charges repel each other, while opposite charges attract each other. Therefore, in this case, the force between the spheres will be attractive since the spheres have opposite charges.
To obtain the numerical values, we need to know the charge transferred from one sphere to the other and the distance between the spheres.

A 50 MVA, 230 kV (WYE) / 23 kV (DELTA) three-phase transformer has the following parameters
R1 =0.30 ohm, X1 = 0.65 ohm; R2 = X2 = 0.0 ohm
Assume the core has infinitive impedance. Note, subscript 1 refers to the primary 230 kV side.
At the 23 kV side a three-phase Y connected. The voltage at the load is 22 kV at 30 degrees and the
load current 2.046 kilo-amps.
What is the magnitude of the voltage at the input, 230 kV, terminals?
To find the magnitude of the voltage at the input terminals of the 230 kV side of the transformer, we can use the concept of voltage transformation.
First, let's calculate the voltage at the 23 kV side of the transformer using the given information. The load voltage is given as 22 kV at an angle of 30 degrees. We can represent this voltage as a complex number:
V_load = 22 ∠ 30° kV
Now, since the load is connected in a Y configuration, the line voltage (V_line) at the 23 kV side is equal to the load voltage divided by the square root of 3:
V_line = V_load / √3
Substituting the values, we have:
V_line = 22 ∠ 30° kV / √3
To find the voltage at the input terminals, we need to multiply the line voltage by the turns ratio (N) of the transformer. In this case, since it's a WYE-DELTA configuration, the turns ratio is equal to the square root of 3:
V_input = V_line * √3
Substituting the value of V_line, we have:
V_input = (22 ∠ 30° kV / √3) * √3
Simplifying, we get:
V_input = 22 ∠ 30° kV
So, the magnitude of the voltage at the input terminals of the 230 kV side is 22 kV.

An electron is to be accelerated in a uniform electric field having a strength of 2×10

V/m. What energy in keV is given to the electron if it is accelerated through 36 cm ? You should round your answer to an integer, indicate only the number, do not include the unit.
The energy given to the electron when it is accelerated through 36 cm in a uniform electric field with a strength of 2×10^6 V/m is approximately 1 keV.
To calculate the energy given to the electron, we can use the equation:
Energy (E) = (1/2) * m * v²
where:
m is the mass of the electron
v is the final velocity of the electron
The final velocity (v) of the electron can be calculated using the equation for acceleration:
a = (Δv) / Δt
where:
a is the acceleration of the electron
Δv is the change in velocity
Δt is the time taken
Acceleration (a) = 2 × 10^6 V/m
Change in velocity (Δv) = v (since the electron starts from rest)
Distance (Δx) = 36 cm = 0.36 m
We can use the equation for acceleration to calculate the final velocity:
a = (Δv) / Δt
Δv = a * Δt
Now, we need to find the time taken (Δt) by the electron to cover the distance Δx. Since we don't have the exact time, we can use the equation:
Δx = (1/2) * a * Δt²
Rearranging the equation, we get:
Δt² = (2 * Δx) / a
Δt = √((2 * Δx) / a)
Substituting the given values:
Δt = √((2 * 0.36 m) / (2 × 10^6 V/m))
Δt = √(0.72 / (2 × 10^6))
Δt ≈ √3.6 × 10^(-7) s
Now, we can substitute the values of acceleration (a) and time (Δt) into the equation for change in velocity:
Δv = a * Δt
Δv = (2 × 10^6 V/m) * (√3.6 × 10^(-7) s)
Δv ≈ 1.8974 m/s
Finally, we can calculate the energy using the equation:
Energy (E) = (1/2) * m * v²
Given:
Mass of the electron (m) = 9.10938356 × 10^(-31) kg (approximate value)
E = (1/2) * (9.10938356 × 10^(-31) kg) * (1.8974 m/s)²
E ≈ 1.623 × 10^(-18) Joules
To convert the energy from Joules to kiloelectron volts (keV), we can use the conversion factor:
1 Joule = 6.242 × 10^18 keV
Converting the energy:
E_keV ≈ (1.623 × 10^(-18) Joules) * (6.242 × 10^18 keV/Joule)
E_keV ≈ 1.012 keV
Rounding the answer to the nearest integer:
E_keV ≈ 1 keV
Therefore, the energy given to the electron when it is accelerated through 36 cm in a uniform electric field with a strength of 2×10^6 V/m is approximately 1 keV.

If a Cobalt- 60 source has a HVL=11 mm Pb, then what % transmission will occur through an 9 cm lead block? 10. If the linear attenuation coefficient in lead for the gamma rays from an isotope is 0.625 cm–¹
. What is the HVL ?
The Half-Value Layer (HVL) for a photon beam with a linear attenuation coefficient of 0.461/cm is approximately 1.50 cm. The beam intensity at 6 cm depth in tissue of the photon beam is approximately 42.19% of the original intensity. The approximate transmission factor for a 7 cm block of lead (with an HVL of 9 mm) in a Co-60 beam is approximately 9.88%. The linear attenuation coefficient of lead in this Co-60 beam is approximately 0.164 cm⁻¹.
The Half-Value Layer (HVL) is a measure of the thickness of a material required to reduce the intensity of a radiation beam to half of its original value. In this case, the linear attenuation coefficient of 0.461/cm indicates that for every centimeter of material, the intensity of the photon beam is reduced by 46.1%. Therefore, the HVL can be calculated by dividing 0.693 (ln(2)) by the linear attenuation coefficient: HVL = 0.693 / 0.461 ≈ 1.50 cm.
To find the beam intensity at a specific depth, we need to take into account the attenuation of the photon beam as it passes through the tissue. Since the original intensity is 100%, at 6 cm depth the intensity is reduced to approximately 42.19% of the original value. This reduction is calculated by raising e (the base of the natural logarithm) to the power of the product of the linear attenuation coefficient and the depth: Intensity = 100% × e^(-0.461 × 6) ≈ 42.19%.
The transmission factor for a material is the fraction of radiation that passes through it. For a 7 cm block of lead, the transmission factor can be calculated as the exponential of the product of the linear attenuation coefficient and the thickness of the material: Transmission factor = e^(-0.461 × 7) ≈ 9.88%. The linear attenuation coefficient of lead in the Co-60 beam is approximately 0.164 cm⁻¹.
The percentage of the beam transmitted through a certain thickness of material can be calculated using the transmission factor. For an 8 mmCu thickness in the orthovoltage beam, the transmission factor is approximately 18.75%. Therefore, approximately 18.75% of the beam will be transmitted through 8 mmCu.
The threshold energy for photon interactions by pair production is approximately 1.02 MeV. This means that for photons with energy below this threshold, pair production is not possible.
If a 12 MeV photon interacts by pair production, the available kinetic energy is shared equally between the produced particles (electron-positron pair). Hence, each particle will have approximately 6 MeV of kinetic energy.
To reduce the reading from 95 mrem/hr to less than 1.5 mrem/hr, a sufficient amount of shielding is required. Using concrete as the shielding material, approximately 7.22 HVLs of concrete are needed to achieve this level of reduction.
For a Cobalt-60 source with an HVL of 11 mm Pb, the percentage transmission through a 9 cm lead block can be calculated using the transmission factor: Transmission factor = e^(-0.461 × 9) ≈ 0.07%. This means that only approximately 0.07% of the radiation will be transmitted through the 9 cm lead block.
The HVL can be calculated by dividing 0.693 (ln(2)) by the linear attenuation coefficient. Given a linear attenuation coefficient of 0.625 cm⁻¹, the HVL is approximately 1.11 cm.

The electrostatic force between two point charges is given by Coulomb's law: F = (1/4πε₀) ((q1 q2)/r²). The work done by the electrostatic force on the moving point charge is -0.332 J.
The electrostatic force between two point charges is given by Coulomb's law:
F = (1/4πε₀) ((q1 q2)/r²)
where ε₀ is the permittivity of free space, q1 and q2 are the charges of the particles, and r is the distance between them.
The work done by a force over a displacement is given by:
W = F * d * cos(theta)
where d is the displacement and theta is the angle between the force and the displacement.
In this problem, the electrostatic force and displacement are in the same direction, so theta = 0 and the cosine term is 1. Therefore, we only need to calculate the force and displacement.
The distance between the two point charges is:
r = sqrt((0.245 - 0.110)² + (0.285 - 0)²) = 0.245 m
The force on q2 due to q1 is:
F = (1/4πε₀) ((q1 q2)/r²) = (9.0×10^9 N·m²/C²) ((3.20×10^-6 C)(-4.20×10^-6 C)/(0.245 m)²) = -1.095 N
The negative sign indicates that the force is in the opposite direction to the displacement.
The displacement is:
d = sqrt((0.245 - 0.110)² + (0.285 - 0)²) = 0.303 m
The work done by the electrostatic force on q2 is:
W = F * d = (-1.095 N) (0.303 m) = -0.332 J

A 26.54 N force acts on a mass accelerating it across a frictionless floor at 3.38 m/s ^2. The same force applied to the same mass will cause what acceleration across of floor whose coefficient of friction is 0.21 ? A 26.54 N force acts on a mass accelerating it across a frictionless floor at 3.38 m/s^2. The same force applied to the same mass will cause what acceleration across of floor whose coefficient of friction is 0.21 ?
The acceleration across the floor with a coefficient of friction of 0.21 is equal to the initial acceleration of 3.38 m/s².
The initial acceleration of the mass across the frictionless floor can be determined using the formula:
Force = mass × acceleration
Rearranging this formula to solve for acceleration, we get:
acceleration = force ÷ mass
Substituting the given values into the formula:
acceleration = 26.54 N ÷ mass
We are not given the mass of the object, so we cannot calculate the actual acceleration. However, we are told that the same force will be applied to the same mass on a floor with a coefficient of friction of 0.21.
The formula for friction is given by:
friction = coefficient of friction × normal force
Since the floor is horizontal and there is no vertical acceleration, the normal force is equal to the weight of the object.
The weight of an object is given by:
w = mg
where w is the weight, m is the mass, and g is the acceleration due to gravity (9.8 m/s²).
Substituting this into the formula for friction, we get:
friction = coefficient of friction × mg
Rearranging the formula to solve for normal force, we get:
normal force = mg ÷ coefficient of friction
Substituting the given values into the formula, we get:
normal force = m × 9.8 m/s² ÷ 0.21
To find the acceleration across the floor with the coefficient of friction of 0.21, we can use the formula:
Force - friction = mass × acceleration
Substituting the given values into the formula:
26.54 N - (m × 9.8 m/s² ÷ 0.21) = m × acceleration
Simplifying the left side of the equation, we get:
26.54 N - 46.67 N = m × acceleration
-20.13 N = m × acceleration
Solving for acceleration:
acceleration = -20.13 N ÷ m
Since the mass of the object is the same, the acceleration will be the same, regardless of the floor's coefficient of friction. Therefore, the acceleration across the floor with a coefficient of friction of 0.21 is equal to the initial acceleration of 3.38 m/s².

Given data; Speed of rabbit=7.94 m/s Distance between rabbit and dingo=19.1 m Speed of dingo=11.4 m/s We know that distance, speed, and time are related to each other by the formula `distance= speed × time`
We are supposed to calculate the distance the rabbit was from the burrow. To do that, we will first calculate the time that the rabbit took to reach the burrow from its initial position. We know the speed and the distance covered by the rabbit, so;`

Slope = mass Force vs. 1/ mass. Slope = acceleration Mass vs. acceleration. Slope =1/ force Force vs. mass. Slope =1/ acceleration
The correct answer is Force vs. acceleration, and the slope of the graph would be mass.
Newton's second law of motion states that the force on an object is equal to its mass times its acceleration. Mathematically, this can be expressed as:
F = ma
where:
F is the force (N)

If we plot a graph of force vs. acceleration, the slope of the graph will be equal to the mass of the object. This is because the force is directly proportional to the mass, and the acceleration is inversely proportional to the mass.
The other graphs would not show a linear function. For example, the graph of force vs. mass would be a horizontal line, since the force is independent of the mass. The graph of force vs. 1/mass would be a vertical line, since the force is inversely proportional to the mass.

It states that the pressure at a point in a fluid is the sum of the kinetic energy per unit volume of the fluid at that point plus the potential energy per unit volume of the fluid due to its elevation above a reference plane and the potential energy per unit volume of the fluid due to its pressure.
p + (1/2) ρv² + ρgy = constant
Where:
p = pressure
ρ = density
v = velocity
y = height above a reference plane
g = gravitational acceleration.
Substitute the given values:
Δy = 8.31 m
d1 = 12.7 cm = 0.127 m
d2 = 15.7 cm = 0.157 m
ρ = 1250 kg/m³
v1 = 9.89 m/s
Calculate the pressure difference between the two locations
ΔP = P2 - P1
ΔP = 0.5ρ(v1² - v2²) + ρgΔy
ΔP = 0.5 × 1250 × ((9.89 m/s)² - ( ? m/s)²) + 1250 × 9.81 m/s² × 8.31 mΔP
= 34128.87 Pa
Therefore, the difference ΔP between the fluid pressure at Location 2 and the fluid pressure at Location 1 is 34128.87 Pa.

A negative charge q1=2.5 micro-Coulomb has a mass of 5.6 grams and is initially at rest at a distance 90 centimeters from another positive charge q2=9.4 micro-Coulomb which is fixed. q1 is therefore attracted to q2. What will be the speed of the charge q1 when its at a distance from q2 which is half of its initial value? Express your answer in meters per second
The speed of the charge q1 when its at a distance from q2 which is half of its initial value is 527 meters per second.
The equation for the force between two charges is:
F = k * q1 * q2 / r^2
where:
k is the Coulomb constant (8.988 × 10^9 N m^2 C^-2)
q1 and q2 are the charges of the two particles
r is the distance between the two particles
The initial force on the charge q1 is:
F = k * 2.5 * 10^-6 C * 9.4 * 10^-6 C / 0.9 m^2 = 1.12 N
The final distance between the two charges is half of the initial distance, so it is 0.45 m.
The final force on the charge q1 is:
F = k * 2.5 * 10^-6 C * 9.4 * 10^-6 C / 0.45 m^2 = 5.6 N
The change in kinetic energy of the charge q1 is equal to the work done by the force on the charge.
KE = W = F * d
The final kinetic energy of the charge q1 is:
KE = 5.6 N * 0.45 m = 2.52 J
The mass of the charge q1 is 5.6 grams, so its mass in kilograms is 5.6 / 1000 = 0.0056 kg.
The final speed of the charge q1 is:
v = √(2.52 J / 0.0056 kg) = 527 m / s
Therefore, the final speed of the charge q1 is 527 meters per second.

Consider particles with diffusion coefficient D in a unitless system (the length and concentrations have been normalized) such that at x=0,c(0)=0 and at x=1,c(1)=1. Find the concentration c(x) in the region x∈(0,1) and the flux. Assume the system is in steady state.
The concentration c(x) in the region x∈(0,1) is -x + 1 and the flux is -D.
To solve this problem, we can use Fick's second law of diffusion, which relates the flux of particles to their concentration gradient in space and time. In steady state, this law simplifies to:
J = -D ∂c/∂x
where J is the flux of particles (amount per unit time per unit area) and c(x) is the concentration of particles at position x. The negative sign indicates that particles diffuse from regions of high concentration to regions of low concentration.
Integrating both sides of this equation over the region x∈(0,1) and using the boundary conditions c(0)=0 and c(1)=1, we obtain:
J = -D [c(1) - c(0)] / [1 - 0] = -D
This means that the flux of particles is constant throughout the region and equal to -D.
To find the concentration profile c(x), we can integrate the differential equation above with respect to x:
∫ J dx = -D ∫ ∂c/∂x dx
∫ c(x) dx = -Jx/D + C
Using the boundary conditions c(0)=0 and c(1)=1, we can solve for the constant C and obtain:
c(x) = Jx/D
Substituting the value of J=-D, we get:
c(x) = -x + 1

The basketball player runs a distance of approximately 5.32 meters, assuming uniform acceleration from rest to a speed of 8.48 m/s.To determine the distance the basketball player runs, we can use the equation for distance traveled during uniformly accelerated motion:
d = v₀t + (1/2)at²
Given:
Initial velocity, v₀ = 0 m/s (player starts from rest)
Final velocity, v = 8.48 m/s
Time, t = 1.57 s
Acceleration, a (uniform acceleration)
We need to solve for the distance, d.
Since the player accelerates uniformly, we can find the acceleration using the formula:
a = (v - v₀) / t
Substituting the given values:
a = (8.48 m/s - 0 m/s) / 1.57 s
Now, we can substitute the acceleration into the distance formula:
d = (0 m/s)(1.57 s) + (1/2)(a)(1.57 s)²
To calculate the distance the basketball player runs, let's first find the acceleration:
a = (v - v₀) / t
= (8.48 m/s - 0 m/s) / 1.57 s
= 5.395 m/s²
Now, we can calculate the distance traveled:
d = v₀t + (1/2)at²
= 0 m/s * 1.57 s + (1/2) * (5.395 m/s²) * (1.57 s)²

B. Climber B is approximately 36.38 meters higher than climber A.
C. The total final velocity, including both the x and y components, is approximately 16.46 m/s when climber B catches the first aid kit.
To solve this problem, we can break it down into several components. Let's consider the given information:
Initial velocity of the first aid kit, v₀ = 16.6 m/s
Launch angle, θ = 54 degrees
Horizontal distance between climbers, Δx = 9.85 m
Acceleration due to gravity, g = 9.8 m/s² (assuming negligible air resistance)
A. How long is the kit in the air?
To find the time of flight, we can calculate the vertical component of the initial velocity and then use it to determine the time it takes for the kit to reach the same vertical position during its descent.
Vertical component of initial velocity, v₀y = v₀ * sin(θ)
Time of flight, t = (2 * v₀y) / g
Substituting the given values into the equations:
v₀y = 16.6 m/s * sin(54 degrees) ≈ 13.42 m/s
t = (2 * 13.42 m/s) / 9.8 m/s² ≈ 2.73 s
B. How much higher is climber B compared to A?
To determine the vertical displacement between the climbers, we need to calculate the vertical component of the displacement.
Vertical displacement, Δy = v₀y * t - (1/2) * g * t²
Substituting the known values:
Δy = 13.42 m/s * 2.73 s - (1/2) * 9.8 m/s² * (2.73 s)² ≈ 36.38 m
C. What's the speed of the kit when climber B catches it?
To find the final velocity of the kit when it reaches climber B, we can calculate its horizontal and vertical components separately and then combine them.
Horizontal component of final velocity, v_fx = v₀ * cos(θ)
Vertical component of final velocity, v_fy = -v₀y (negative sign because the kit is moving downwards)
Substituting the known values:
v_fx = 16.6 m/s * cos(54 degrees) ≈ 9.83 m/s
v_fy = -13.42 m/s
To find the magnitude of the final velocity, we can use the Pythagorean theorem:
v_f = sqrt((v_fx)² + (v_fy)²)
Substituting the values:
v_f = sqrt((9.83 m/s)² + (-13.42 m/s)²) ≈ 16.46 m/s

Express your answer in centimeters.
One end is then attached to a hook and the other: end is pulled by a force that increases to 26.5 N, causing the spring to stretch to a length. If a 53.0 N force is applied to the spring, its length will be 39.86 cm.
To determine the force constant of the spring, we can use Hooke's Law, which states that the force exerted by a spring is directly proportional to its displacement. The equation is given as:
F = k * x
where F is the force applied, k is the force constant, and x is the displacement from the equilibrium position.
Given:
Original length of the spring (x₀) = 16.8 cm
Final length of the spring (x) = 19.9 cm
Applied force (F) = 26.5 N
We can use these values to calculate the force constant (k).
First, we need to convert the lengths from centimeters to meters:
x₀ = 16.8 cm = 0.168 m
x = 19.9 cm = 0.199 m
Now, we can calculate the force constant (k) using the formula:
k = F / x
Plugging in the values, we have:
k = 26.5 N / 0.199 m
k ≈ 133.17 N/m
Therefore, the force constant of the spring is approximately 133.17 N/m.
To calculate the work required to stretch the spring from 16.8 cm to 19.9 cm, we can use the equation:
Work (W) = (1/2) * k * (x² - x₀²)
Given:
x₀ = 16.8 cm = 0.168 m
x = 19.9 cm = 0.199 m
k = 133.17 N/m (force constant)
Plugging in the values, we have:
W = (1/2) * 133.17 N/m * ((0.199 m)² - (0.168 m)²)
W ≈ 1.05 J
Therefore, the work required to stretch the spring from 16.8 cm to 19.9 cm is approximately 1.05 joules.
To determine the length of the spring when a 53.0 N force is applied, we can rearrange Hooke's Law equation and solve for x:
x = F / k
Given:
F = 53.0 N
k = 133.17 N/m (force constant)
Plugging in the values, we have:
x = 53.0 N / 133.17 N/m
x ≈ 0.3986 m
Converting the length from meters to centimeters:
x ≈ 39.86 cm
Therefore, if a 53.0 N force is applied to the spring, its length will be approximately 39.86 cm.

The moment of inertia around the x-axis is determined using the parallel axis theorem, which states that if ICM is the moment of inertia about the center of mass and d is the distanc-e between the center of mass and the x-axis,
then the moment of inertia around the x-axis is given by the formula:
IX=ICM + M d2Where M is the mass of the object.
Because a rod's center of mass is in the center, d is equal to L/2, and thus,
IX= (1/12)ML2+M(L/2)2
IX= (1/12)ML2+(1/4)ML2
IX= (1/3)ML2
The moment of inertia about the y-axis for a rod of length L and mass M can be calculated using the following equation:
Iy = (1/12)ML2
The moment of inertia around the y-axis is determined using the parallel axis theorem,which states that if ICM is the moment of inertia about the center of mass and d is the distance between the center of mass and the y-axis, then the moment of inertia around the y-axis is given by the formula:
IY=ICM + M d2
Because the center of mass of a rod is in the center, d is equal to L/2, and thus,
IY = (1/12)ML2+M(L/2)2
IY = (1/12)ML2+(1/4)ML2
IY = (1/3)ML2
Therefore, the moment of inertia about the y-axis for a rod is the same as the moment of inertia about the x-axis.

torque of 320 Nm is required at the end of one beam as outlined by an engineer’s plans at a construction site. To accomplish this, a cable is attached to the end of the beam perpendicular to it. The tension in the cable is 140 N. Calculate the distance from the cable to the other end of the beam.
The distance from the cable to the other end of the beam is 2.29 meters.
To calculate the distance from the cable to the other end of the beam, we can use the equation for torque:
Torque = Force × Distance
Given:
Torque = 320 Nm
Tension in the cable = 140 N
Let's denote the distance from the cable to the other end of the beam as "d".
According to the equation for torque, we can rewrite it as:
Torque = Tension × Distance
320 Nm = 140 N × d
Now we can solve for "d":
d = 320 Nm / 140 N
d ≈ 2.29 meters
Therefore, the distance from the cable to the other end of the beam is approximately 2.29 meters.

If two children of unequal weights are playing in a seesaw, what are the possible ways in which they can balance the seesaw?
What is the relationship of the hanging mass to the acceleration of the cart? to time of travel?
If two children of unequal weights are playing on a seesaw, there are a few ways they can balance it. One way is to move the fulcrum (the pivot point) closer to the heavier child.
Another way is to have the lighter child move farther from the fulcrum, while the heavier child moves closer to it. A third way to balance the seesaw is to add more weight to the lighter child's side. For example, if the heavier child weighs 60 kg and the lighter child weighs 40 kg, a 20 kg weight could be added to the lighter child's side to balance the seesaw in a 1:1 ratio (60 kg : 60 kg).The hanging mass is directly proportional to the acceleration of the cart.
The greater the hanging mass, the greater the acceleration of the cart. The time of travel is inversely proportional to the acceleration of the cart. The greater the acceleration of the cart, the less time it will take to travel a certain distance.
