The magnitude of the torque exerted on the disk when a constant force of 34 N is applied to the string wrapped around it is 15.64 N·m.

The magnitude of the torque can be calculated using the formula: torque = force  ˣ radius. Plugging in the given values, the torque is 34 N  ˣ  0.46 m = 15.64 N·m.

What is the angular speed of the disk 0.85 seconds after reaching an initial angular speed of 6 radians/s?

The change in angular speed can be determined using the formula: change in angular speed = torque / moment of inertia ˣ time. Plugging in the values, the change in angular speed is (15.64 N·m) / (2.1 kg·m²)  ˣ (0.85 s) = 0.118 rad/s.

To find the final angular speed, we add the change in angular speed to the initial angular speed: 6 rad/s + 0.118 rad/s = 6.118 rad/s.

Therefore, the angular speed of the disk 0.85 seconds later is 6.118 radians/s.

So, with an acceleration of 2.35 m/s², the VW Beetle takes 11.38 seconds to reach 60.0 miles per hour. As a result, the top-fuel dragster's acceleration is 38.3 m/s².

The rate of change of velocity is defined as acceleration. Acceleration usually indicates that the speed is changing, however this is not always the case. When an item goes on a circular course with a constant speed, it is still accelerating since its velocity direction changes. Acceleration is the rate at which velocity varies over time, both in terms of speed and direction. A point or object travelling in a straight path is accelerated if it accelerates or decelerates.

Here,

a. To find the time it takes for the VW Beetle to reach 60.0 mi/h with an acceleration of 2.35 m/s², we can use the equation:

v = a * t

Where v is the final velocity, a is the acceleration, and t is the time. To convert 60.0 mi/h to m/s, we can use the conversion factor 1 mi/h = 0.447 m/s:

60.0 mi/h = 60.0 * 0.447 m/s = 26.82 m/s

So we can solve for t:

t = v / a = 26.82 m/s / 2.35 m/s² = 11.38 s

So it takes the VW Beetle 11.38 s to reach 60.0 mi/h with an acceleration of 2.35 m/s².

b. To find the acceleration of the top-fuel dragster, we can use the equation and the information given:

v = a * t

Where v is the final velocity, a is the acceleration, and t is the time. To convert 60.0 mi/h to m/s, we can use the conversion factor 1 mi/h = 0.447 m/s:

60.0 mi/h = 60.0 * 0.447 m/s = 26.82 m/s

And we know t = 0.700 s. So we can solve for a:

a = v / t = 26.82 m/s / 0.700 s = 38.3 m/s²

So it takes the VW Beetle 11.38 s to reach 60.0 mi/h with an acceleration of 2.35 m/s². So the acceleration of the top-fuel dragster is 38.3 m/s².

The distance traveled during the driver's reaction time is 7.5 meters, the distance traveled while decelerating is 22.5 meters And  the total stopping distance is 30 meters.

To determine the distance the driver travels before applying the brakes, we can use the following steps:

1. Calculate the distance traveled during the driver's reaction time.

  Given:

  Reaction time (t_reaction) = 0.50 seconds

  Initial velocity (v_initial) = 15 m/s

The distance traveled during the reaction time can be calculated using the formula,

  d_reaction = v_initial * t_reaction

 d_reaction = 15 m/s * 0.50 s

  d_reaction = 7.5 meters

Therefore, the distance traveled during the driver's reaction time is 7.5 meters.

2. Calculate the distance traveled while decelerating.

  Given:

  Maximum deceleration (a_deceleration) = -5.0 m/s^2 (negative because it represents deceleration)

  Final velocity (v_final) = 0 m/s (since the car comes to a stop)

  The distance traveled while decelerating can be calculated using the formula:

  d_deceleration = (v_final^2 - v_initial^2) / (2 * a_deceleration)

  d_deceleration = (0^2 - 15^2) / (2 * (-5.0))

  d_deceleration = (-225) / (-10)

  d_deceleration = 22.5 meters

Therefore, the distance traveled while decelerating is 22.5 meters.

3. Calculate the total stopping distance.

  The total stopping distance is the sum of the distance traveled during the reaction time and the distance traveled while decelerating.

Total stopping distance = d_reaction + d_deceleration

Total stopping distance = 7.5 meters + 22.5 meters

Total stopping distance = 30 meters

Therefore, the total stopping distance is 30 meters.

In summary, considering a reaction time of 0.50 seconds and a maximum deceleration of 5.0 m/s^2, the driver would travel 7.5 meters during her reaction time and an additional 22.5 meters while decelerating, resulting in a total stopping distance of 30 meters.

The power P that makes the equation \(a=2xt^p\) dimensionally consistent is 1.

When we want to make an equation dimensionally consistent, we need to ensure that both sides of the equation have the same units. In this case, the unit of acceleration is \(m/s^2\), the unit of time is s, and the unit of distance is m. By substituting these units into the given equation, we get:

\(m/s^2 = 2m * s^p\)

Simplifying this expression, we get:

\(s^(^2^-^p^) = m^(^1^-^p^)\)

To make both sides of the equation equal, we need to set the powers of s and m equal to each other. Therefore, we get:

2 - p = 1 - p

Solving for p, we get:

p = 1

Therefore, the power P that makes the equation dimensionally consistent is 1.

Answer:

c. divides by 4 the gravitational force between them

Explanation:

Newton's law of gravity says:

 F1 = G(m1*m2)/r^2

where G is the gravitational constant, m1 and m2 are the masses of objects 1 and 2, and r is the distance between the two masses.

Doubling the distance would result in:

The new distance would be = 2r

F2 = G(m1m2)/(2r)^2

F2 = G(m1m2)/4r^2

F2 = (1/4)(G(m1m2)/r^2)

F2 = (1/4)F1

The new force, F2, at twice the distance is 1/4 that of the original force, F1.

The horizontal acceleration of the crate is 0.064 m/s².

Newton's second law of motion can be written as F = ma,

where F is the force, m is the mass, and a is the acceleration. In this case, we have F = 14.5 N, m = 225 kg, and we want to find a. Solving for a, we get

a = F / m = 14.5 N / 225 kg

  = 0.064 m/s²

This means that the crate will accelerate horizontally at a rate of 0.064 m/s². This means that, in one second, the crate's velocity will increase by 0.064 m/s. For example, if the crate is initially at rest, it will be moving at 0.064 m/s after one second, 0.128 m/s after two seconds, and so on.

The crate's acceleration is possible because the surface is frictionless. If there were friction between the crate and the surface, the crate would not be able to accelerate as quickly.

The amount of friction would depend on the coefficient of friction between the crate and the surface. The higher the coefficient of friction, the more friction there would be, and the slower the crate would accelerate.

By applying Newton's second law and solving for acceleration, we find that the acceleration of the crate is approximately 0.631 m/s^2.

The subject of this question is Physics, specifically, we're dealing with Newton's second law of motion, which can be stated as: Force = mass x acceleration (F = ma). From the given information, we know that the force acting on the crate is 14.5 N and the weight of the crate is 225 N. Since weight equals mass times gravity (W = mg) and given that gravity (g) is approximately 9.8 m/s^2, we can find the mass (m) by dividing the weight by gravity (m = W/g). So, the mass of the crate is 225 N / 9.8 m/s^2 = 22.96 kg.

Now we can use Newton's second law (F = ma) to calculate acceleration (a). Rearranging the formula gives us a = F/m. Substituting the values gives us: a = 14.5 N / 22.96 kg = 0.631 m/s^2. Therefore, the horizontal acceleration of the crate is approximately 0.631 m/s^2.

The sled will slide horizontally a distance of 18.94 m before coming to a stop.

The horizontal motion of the sled is under the influence of frictional forces acting opposite to the direction of motion. When the sled comes to rest, the frictional force would have done work to bring the sled to a halt.

To find the distance the sled would move, use the work-energy theorem which states that the work done by all the forces acting on a body is equal to the change in the kinetic energy of the body.

Kinetic energy = 1/2mv²where m is the mass and v is the velocity of the body

Initial velocity of the sled = 9.2 m/s

Mass of the sled and students = 120 kg

Coefficient of friction = 0.23There is no vertical motion so the potential energy remains constant and is ignored.The sled starts with kinetic energy equal to the work done by all the forces acting on it. The frictional force does negative work and removes the kinetic energy and bring the sled to a stop.Work done by friction = force × distance.

The force of friction is proportional to the normal force acting on the sled. We do not know the normal force acting on the sled, but we know the gravitational force acting on the sled and this gives the normal force.Force of gravity = mass × acceleration due to gravity = mg.

The normal force = force of gravity × cos (0) = mg × cos (0) = mg.

The angle between the horizontal and the slope is zero, so the angle of inclination is zero.

Work done by friction = force of friction × distance

Work done by friction = frictional force × distance

Work done by friction = μmg × distance

Work done by friction = kinetic energy at start of slide = 1/2mv²

Work done by friction = (1/2)(mass)(initial velocity)²

Work done by friction = (1/2)(120 kg)(9.2 m/s)²

Work done by friction = 5 137.6 J

Frictional force = μmg

Frictional force = (0.23)(120 kg)(9.8 m/s²)

Frictional force = 270.96 N270.96 N × distance = 5 137.6 J

distance = 5 137.6 J/270.96 N

A structural deficit is a budgetary deficit that results from a fundamental mismatch between a government's expenses and its revenues in the long term. A structural deficit is distinguished from the cyclical deficit, which arises from fluctuations in economic growth.

The structural deficit acts as an automatic stabilizer and increases during recessions. The automatic stabilizer refers to any action or mechanism that assists to reduce the swings in an economy without any intervention from policymakers. One instance of an automatic stabilizer is unemployment compensation. This is because, in an economic downturn, unemployment compensation is increased automatically, which, in turn, improves consumer spending. Structural deficits occur when government spending exceeds revenue collections, which is frequently the result of increased spending or decreased income. In certain cases, the structural deficit is the consequence of a tax system that does not generate sufficient revenue to cover government expenditures. A structural deficit remains the same at full employment and is not the same as a cyclical deficit.

Answer: T = 40%

Explanation: The definition of Transmittance is a part of the incident light that passes through a surface or material moves through the other side of the surface. It is represented as T and is defined as the ratio of the intensity of incident light to the intensity of light that passes through the surface:

\(T=\frac{I}{I_{0}}\)

where

I is intensity that passes through

I₀ is incident intensity

When you shine a light on a material and 50% of it is reflected, the remaining 50% will try to pass through. However, 10% is absorbed leaving 40% of the light to move through the other side of the surface.

So, Transmittance of this surface is 40%.
