suppose a car screeches to a halt to avoid an accident. if that car has antilock brakes that pump on and off automatically every fraction of a second, what might the tread marks on the road look like?

Answers

Answer 1

The tread marks on the road from a car with antilock brakes that pump on and off automatically every fraction of a second would likely appear as a series of short, intermittent marks rather than continuous skid marks. The presence of these intermittent marks indicates that the ABS is functioning correctly and assisting the driver in maintaining control while stopping the vehicle in an emergency situation.

Antilock brakes are designed to prevent the wheels from locking up during braking, allowing the driver to maintain steering control. When the brakes are applied, the antilock braking system (ABS) rapidly pumps the brakes on and off, reducing the braking force to each wheel in a controlled manner. This pumping action helps to prevent the wheels from completely locking up and skidding on the road surface.

As a result, the tread marks left by a car with ABS would not be continuous skid marks but rather a series of shorter, intermittent marks. These marks would indicate the points where the wheels momentarily grip the road as the ABS modulates the braking pressure. The presence of these intermittent marks indicates that the ABS is functioning correctly and assisting the driver in maintaining control while stopping the vehicle in an emergency situation.

A - 28.4-μC charge is placed 16.4 cm from a charge q, the force between the two charges is 1240 N. What is the value of q?

Answers

Answer:

1.31×10⁻⁴ C or 131 μC

Explanation:

From the question,

Applying Coulomb's Law,

F = kqq'/r²..................... Equation 1

Where F = Force between the charges, q = first charge, q' = second charge, r = distance between the charges, k = coulomb's constant.

make q' the subject of the equation

q' = F×r²/(kq)

q' = Fr²/kq................ Equation 2

Given: F = 1240 N, r = 16.4 cm = 0.164 m, q = 28.4 μC = 2.84×10⁻⁵ C,

Constant: k = 8.98×10⁹ Nm/C²

Substitute these values into equation 2

q' = (1240×0.164²)/[(2.84×10⁻⁵)×(8.98×10⁹)

q' = (33.35104)/(25.5032×10⁴)

q' = 1.31×10⁻⁴ C

q' = 131 μC

A horizontal force of magnitude 47.3 N pushes a block of mass 3.95 kg across a floor where the coefficient of kinetic friction is 0.643. (a) How much work is done by that applied force on the block-floor system when the block slides through a displacement of 4.89 m across the floor?

Answers

The work done by the applied force is -117.42 J.

Force applied on the block = 47.3 N

Mass of the block = 3.95 kg

Coefficient of kinetic friction = 0.643

Displacement = 4.89 m

(a) It is represented by the formula,

W = Fd cos θ

Where,

W = work done by the force,

F = magnitude of the applied force,

d = distance covered by the object,

θ = angle between the applied force and the displacement of the object.

W = Fd cos θ

For a horizontal force, θ = 0

Therefore, W = Fd cos 0 = Fd

Since the block is moving with a constant velocity, the net force on the block must be zero. Thus, the force of friction acting on the block is equal in magnitude and opposite in direction to the applied force.

The force of friction on the block,

f = μkN

where,

μk is the coefficient of kinetic friction,

N is the normal force exerted on the block by the floor

Since the block is on a horizontal floor, the normal force is equal in magnitude and opposite in direction to the weight of the block.

Therefore,

N = mg

where,

g is the acceleration due to gravity

Substituting the value of N in the formula of force of friction:

f = μkN= μkmg

The force of friction acting on the block is 0.643 × 3.95 × 9.8 = 24.005 N

Since the net force on the block is zero, the applied force is equal in magnitude to the force of friction acting on the block and is opposite in direction.

Therefore,

F = - 24.005 N

The work done by the external force on the block-floor system is given by,

W = Fd

W = (-24.005 N) × 4.89 m = -117.42 J

Therefore, the work done by the applied force is -117.42 J.

Andrew gathered several different species of seed plants. Which three characteristics do all the plants most likely share? have pollen and flowers; lack phloem have pollen and rhizoids; lack xylem have xylem and phloem; lack pollen have xylem and phloem; lack rhizoids

Answers

The three characteristics that all the plants most likely share are: have xylem and phloem; lack pollen. Option D.

In seed plants, xylem and phloem are essential vascular tissues responsible for the transport of water, nutrients, and sugars throughout the plant. Xylem transports water and minerals from the roots to the rest of the plant, while phloem carries sugars and other organic compounds from photosynthetic regions to other parts of the plant.

The absence of pollen indicates that these plants do not reproduce through the production and dispersal of pollen grains. Instead, they likely reproduce through other means, such as the production of seeds.

This combination of having xylem and phloem while lacking pollen suggests that the plants in question are likely gymnosperms. Gymnosperms are a group of seed plants that include conifers, cycads, ginkgoes, and others. These plants typically produce seeds that are not enclosed within a fruit, and they rely on other methods such as wind or insects for pollination.

It is important to note that this conclusion is based on the provided information and is subject to change depending on further details about the specific characteristics of the gathered plants. SO Option D is correct.

B) 0.0400 M/s
C) 0.0600 M/s
D) 0.0800 M/s
E) 0.100 M/s

Answers

Therefore, the new rate, when the concentration of [A] is increased to 0.400 M, is 0.0800 M/s.

The correct answer is D) 0.0800 M/s.

The given rate law equation is rate = k[A]^1, where k is the rate constant and [A] is the concentration of species A.

If the concentration of [A] is increased from 0.100 M to 0.400 M, we need to determine the new rate.

The rate law equation can be rewritten as:

rate = k[A]

The initial rate is given as 0.0200 M/s when [A] = 0.100 M. We can calculate the rate constant (k) using this information:

0.0200 M/s = k * 0.100 M

Solving for k:

k = 0.0200 M/s / 0.100 M

k = 0.200 M^(-1) s^(-1)

Now, we can calculate the new rate when [A] = 0.400 M using the rate constant we found:

rate = k * [A]

rate = 0.200 M^(-1) s^(-1) * 0.400 M

Answers

Answer:

x_total = 20m

Explanation:

This is an exercise in kinematics, we will look for the distance it travels during the reaction time, where there is no braking, and then the distance during the deceleration.

Distance traveled during response time

           v = x₁ / t

           x₁ = v t

let's calculate

          x₁ = 10 0.75

          x₁ = 7.5 m

Now we calculate the distance during braking, the final speed is zero (v = 0)

         v² = v₀² - 2 a x₂

         x₂ = v₀² / 2 a

let's calculate

         x₂ = 10² / (2 4)

         x₂ = 12.5m

the total stopping distance is

what distinguishes the orbit of pluto from that of the eight major planets of the solar system?

Answers

Pluto's orbit is much more eccentric and inclined compared to the orbits of the eight major planets in the solar system. This means that Pluto's orbit is more elliptical and tilted relative to the plane of the solar system, while the orbits of the major planets are generally more circular and on the same plane.


First, Pluto's orbit is much more eccentric (elongated) than the orbits of the other planets. This means that its distance from the Sun varies more dramatically over the course of its orbit. While the other planets have nearly circular orbits, Pluto's orbit is more oval-shaped.

Second, Pluto's orbit is also more inclined (tilted) relative to the plane of the Solar System. The eight major planets all orbit in roughly the same plane, but Pluto's orbit is tilted at an angle of about 17 degrees. This means that it sometimes travels above and below the plane of the Solar System during its orbit.

Two stationary point charges of +90. 0 μC and -40. 0 μC exert an attractive force on each other of 293 N. What is the distance between the two charges?

Answers

The distance between the two charges is approximately 0.0107 meters, or 10.7 millimeters.

Coulomb's Law, which states that the force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them, can be used to compute the attractive force between two point charges.

Coulomb's Law is formulated as follows:

F = k × |q₁ × q₂| / r²

where:

F = force between the charges (in newtons, N)

k = Coulomb's constant, which is approximately 8.99 x 10⁻⁹Nm²/C²

q₁ and  q₂ = charges of the two point charges (in coulombs, C)

r = distance between the charges (in meters, m)

Given:

q₁ = +90.0 μC = 90.0 x 10⁻⁶C

q₂ = -40.0 μC = -40.0 x 10⁻⁶ C

F = 293 N

k = 8.99 x 10⁹ Nm²/C²

Plugging these values into the formula, we can solve for r:

293 = 8.99 x 10⁹ x |90.0 x 10⁻⁶ x -40.0 x 10⁻⁶| / r²

To simplify the calculation, we can take the absolute value of the product of the charges, since distance is always positive:

293 =  8.99 x 10⁹ x 90.0 x 10⁻⁶ x -40.0 x 10⁻⁶ / r²

Now we can solve for r:

r² = 8.99 x 10⁹ x90.0 x 10⁻⁶ x -40.0 x 10⁻⁶/ 293

r² = 0.000011456

r =  √(0.000011456)

r ≈ 0.0107 m

So, the distance between the two charges would be approximately 0.0107 meters, or 10.7 millimeters.

what is the longest wavelength, in air, of light that will give constructive interference from opposite sides of the reflecting plates? express your answer with the appropriate units.

Answers

The longest wavelength of light that will give constructive interference from opposite sides of the reflecting plates is twice the distance between the plates. The units of λ will depend on the units of d, but it will always be a length (e.g. meters, centimeters, etc.).

To find the longest wavelength that will result in constructive interference, we can use the equation:
2d = mλ
where d is the distance between the reflecting plates, λ is the wavelength of the light, and m is an integer representing the order of the interference pattern.
For constructive interference to occur, the path difference between the waves reflecting off opposite sides of the plates must be an integer multiple of the wavelength. In other words, the waves must be "in phase" and reinforce each other.
Since we want to find the longest wavelength that results in constructive interference, we can set m = 1 (the first order) and solve for λ:
2d = λ
λ = 2d
Answer: In air, the longest wavelength of light that will result in constructive interference from opposite sides of the reflecting plates is twice the distance between the plates.

what must the coefficient of static friction be for a car traveling at 115 km/h around the same turn?

Answers

Generally, the coefficient of static friction should be at least 0.7 for a car traveling at this speed, but this value could be higher depending on the specific conditions.

The coefficient of static friction, or μs, is the ratio of the maximum static force that can be applied without causing slipping to the normal force between two surfaces. The coefficient is affected by the surfaces in contact and the material they are made of.

The tires of a car also have an effect on the coefficient of static friction. Tires with a greater tread depth can provide better grip on the road and therefore have a higher coefficient of static friction than tires with a shallow tread. Tire pressure also plays a role, as low pressure can reduce the coefficient of static friction.

The weight of the vehicle is also an important factor. Heavier vehicles tend to have a higher coefficient of static friction, as the greater mass increases the normal force between the car and the surface.

In conclusion, the coefficient of static friction for a car traveling at 115 km/h around a turn depends on several factors, including the road surface, the vehicle's tires, and the vehicle's weight.

Answers

When the light waves pass through the slit, the wave spreads, diffracting into a pattern on a screen behind it. The diffraction pattern is characterized by a series of bright fringes interspersed with dark ones.

We can calculate the distance between each dark fringe using the formula:dsinθ = mλ, where d is the width of the slit, θ is the angle of the dark fringe, m is the order of the fringe, and λ is the wavelength of the light.Let's now use this formula to solve the given problem. The first minimum occurs when m = 1. Therefore,1 × λ = d sinθ. The slit width is given as 1.31 µm = 1.31 × 10⁻⁶ m, and the angle of the dark fringe is 22.5°.We can convert this angle to radians as follows:θ = 22.5° = 22.5 × π/180 = 0.3937 radians.

Substituting the values into the formula, we get:λ = d sinθ / m= (1.31 × 10⁻⁶) × sin 0.3937 / 1= 7.52 × 10⁻⁷ m = 752 nmTherefore, the wavelength of light that produces its first minimum at an angle of 22.5° when falling on a single slit of width 1.31 µm is 752 nm (more than 100 words).

The driver of a car moving with a uniform speed of 40m/s observes a truck approaching
in the opposite direction with a speed of 20m/s.Calculate the speed of the car relative to that of the truck.

Answers

Answer:

60m/s

Explanation:

Whenever two objects are moving in opposite direction the relative speed is obtained by adding the speeds of the two objects.

Here the two vehicles are moving with speed 20m/s and 40m/s .

So the relative speed of the car relative to that of the truck will be,

(40 + 20 ) m/s

60m/s

what was the original intensity i0, assuming the light started out unpolarized?

Answers

The original intensity I0 is the same as the sum of the intensities transmitted through the two filters and is given by I0 = I1 + I2.

The intensity of light transmitted through two polarizing filters with axes at a relative angle θ is given by the Malus' Law equation, I1 = I0cos^2(θ), where I0 is the original intensity of the unpolarized light. Similarly, when the axes are at a relative angle 90.0°-θ, the intensity is given by I2 = I0sin^2(θ).
To find the original intensity I0, we can use the fact that the sum of the intensities transmitted through the two filters is equal to the original intensity. So, I1 + I2 = I0. Substituting the values of I1 and I2, we get:
I0cos^2(θ) + I0sin^2(θ) = I0
Simplifying this equation, we get:
I0(cos^2(θ) + sin^2(θ)) = I0
Since cos^2(θ) + sin^2(θ) = 1, we get:
I0 = I1 + I2 = I0(cos^2(θ) + sin^2(θ)) = I0
Therefore, the original intensity I0 is the same as the sum of the intensities transmitted through the two filters and is given by I0 = I1 + I2.

complete question:

Suppose I1 is the intensity of light transmitted through two polarizing filters with axes at a relative angle θ, and I2 is the intensity when the axes are at a relative angle 90.0°-θ.

What was the original intensity I0, assuming the light started out unpolarized?

If the light started out unpolarized, then the original intensity i0 would refer to the total intensity of the light before it was polarized.

When light is unpolarized, it vibrates in all possible directions perpendicular to the direction of its propagation. This means that the total intensity of the light is equal to the sum of the intensities of all the individual waves that make it up.
Determining the value of i0 would depend on the specific source of the light and the measurements taken to determine its intensity. However, it is important to note that the polarization of light can affect its intensity. When polarized light is passed through a polarizer, only the component of the light that is parallel to the polarizer's axis is allowed through, which can result in a decrease in intensity. Therefore, if the original intensity i0 was measured after the light had passed through a polarizer, it would not accurately represent the total intensity of the unpolarized light.

The value of i0 would depend on the specific conditions of the unpolarized light source and measurements taken. However, it is important to consider how polarization can affect the intensity of light when making this determination.
