Answers

Answer 1

Agent burt engle is chasing some more "bad" dudes and dudettes, when he notices his fuel gauge is running close to empty. he is approaching a hill (that makes an incline of 30 degrees with the horizontal) whose height is 49 m when suddenly, while travelling at 32 m/s, the car stalls on him.

To determine whether Agent Burt Engle will make it to the crest of the hill or not, we need to consider the forces acting on the car and the work done.

First, let’s calculate the gravitational potential energy (PE) of the car at the base of the hill:

PE = m * g * h

PE = 800 kg * 9.8 m/s² * 49 m

PE = 384,160 J

Now, let’s calculate the work done by the resistance force as the car moves up the hill:

Work = force * distance

The force acting against the car’s motion is the resistance force, which is given as 300 N. The distance traveled up the hill is the height of the hill, which is 49 m.

Work = 300 N * 49 m

Work = 14,700 J

Comparing the work done by the resistance force to the initial potential energy, we can determine if the car will make it to the crest of the hill:

If Work < PE, the car will make it to the crest of the hill.

If Work ≥ PE, the car will not make it to the crest of the hill.

In this case, 14,700 J ≥ 384,160 J, which means the work done by the resistance force is greater than the initial potential energy of the car. Therefore, Agent Burt Engle will not make it to the crest of the hill and will have to call for backup.

Answers

The main answer to A) is that box D experiences the largest change in kinetic energy. This is because the change in kinetic energy is directly proportional to the mass of the object and the square of its velocity.

Box D has the largest mass, so it requires more energy to be pushed and moves at a higher velocity than the other boxes. Therefore, it experiences the largest change in kinetic energy.

The main answer to B) is that box C experiences the smallest change in kinetic energy. This is because the change in kinetic energy is directly proportional to the mass of the object and the square of its velocity. Box C has the smallest mass, so it requires less energy to be pushed and moves at a lower velocity than the other boxes. Therefore, it experiences the smallest change in kinetic energy.

a crate is being pushed across a rough floor surface. if no force is applied on the crate, the crate will slow down and come to a stop. if the crate of mass 50 kg moving at speed 8 m/s comes to rest in 10 seconds, what is the rate at which the frictional force on the crate takes energy away from the crate? select the correct answer 129 j/s 502 j/s 321 j/s 160 j/s 92.1 j/s

Answers

The rate at which the frictional force on the crate takes energy away from the crate is 160 j/s.

To solve this problem, we need to use the formula:

frictional force = (mass x acceleration)

We know the mass of the crate is 50 kg and it comes to rest in 10 seconds, so the acceleration is:

acceleration = (final velocity - initial velocity) / time
acceleration = (0 - 8) / 10
acceleration = -0.8 m/s^2 (negative because it's slowing down)

Now we can calculate the frictional force:

frictional force = (mass x acceleration)
frictional force = (50 kg) x (-0.8 m/s^2)
frictional force = -40 N (negative because it's opposing the motion)

The rate at which the frictional force takes energy away from the crate is given by the formula:

power = (force x velocity)

We know the force is -40 N (negative because it's opposing the motion) and the initial velocity is 8 m/s. We don't know the final velocity, but we can assume it's close to zero since the crate comes to rest. So we'll use an average velocity of 4 m/s.

power = (force x velocity)
power = (-40 N) x (4 m/s)
power = -160 J/s (negative because it's taking energy away)

A thin disk with mass M and radius R rolls down an inclined plane initially released from rest with no slipping. Determine a differential Equation of Motion for the center of mass position, using the x-coordinate parallel to the inclined surface, including a FBD

Answers

The differential Equation of Motion for the center of mass position, using the x-coordinate parallel to the inclined surface is: a = (2/3)g sinθ - (2/3)μg cosθ.

The gravitational force acting on the disk can be split into two components: one perpendicular to the inclined plane, which we'll call N (the normal force), and one parallel to the inclined plane, which we'll call Mg sinθ (where θ is the angle of inclination).

There is also a force of static friction acting on the disk, opposing its motion down the plane. The frictional force can be found as,
f = μN,
where μ is the coefficient of static friction.

Now, let's consider the motion of the disk. Since the disk is rolling without slipping, we can relate the linear velocity v of the center of mass to the angular velocity ω of the disk as,
v = Rω,
where R is the radius of the disk.

The Equation of Motion for the center of mass position can be derived from the sum of forces acting on the disk. We have:
Ma = Mg sinθ - f
where M is the mass of the disk,
a is the acceleration of the center of mass, and
we have used Newton's second law.

To relate the acceleration to the angular velocity, we can use the fact that the tangential acceleration of a point on the rim of the disk is a = Rα, where α is the angular acceleration. We also have the rotational analog of Newton's second law:
Iα = fR
where I is the moment of inertia of the disk about its center of mass.

Substituting the expression for f from above and using the relationship between linear and angular velocity, we get:
Iα = μN R
M(Rα) = Mg sinθ - μN

Substituting α = a/R and I = (1/2)MR^2, we can simplify the equation to:
a = (2/3)g sinθ - (2/3)μg cosθ

a fluid with an initial volume of 0.22 m3 is subjected to a pressure decrease of 1.7×103pa . the volume is then found to have increased by 0.18 cm3 . what is the bulk modulus of the fluid?

Answers

The bulk modulus of the fluid is approximately 2.076 × 10¹² Pa.

To find the bulk modulus of the fluid, we need to use the formula:
Bulk modulus = (change in pressure / (original volume / change in volume))
We are given the initial volume of the fluid as 0.22 m3 and the pressure decrease as 1.7×103pa. We need to convert the change in volume from cm3 to m3, which is 0.18 cm3 = 0.18 × 10^-6 m3.
Bulk modulus = (1.7×103pa / (0.22 m3 / 0.18 × 10^-6 m3))
Bulk modulus = 1.7×103pa / 1.22×10^-4 m3
Bulk modulus = 1.393×10^10 pa
Bulk modulus (B) = -ΔP / (ΔV/V₀)
0.18 cm³ * (1 m/100 cm)³ = 1.8 × 10⁻¹² m³
Now, plug in the values into the formula:
B = -(-1.7 × 10³ Pa) / (1.8 × 10⁻¹² m³ / 0.22 m³)
B = (1.7 × 10³ Pa) / (8.1818 × 10⁻¹²)

​b. a toy car rolling on a carpeted floor

Answers

The velocity of the fish when it hits the water is 22.3 m/s.

The velocity of the diver is 8.85 m/s.

The height to which the runner’s center of mass is raised during the jump is 0.204 m.

Initial height of the bob is 0.224 m.

1) Speed of the bird, v₁ = 20 m/s

Mass of the fish, m = 2.5 kg

Height of the bird, h₁ = 5 m

The total mechanical energy of the fish before dropping is equal to that after dropping.

Total energy = KE + PE

1/2 mv₁² + mgh₁ = 1/2mv₂² + 0

Multiplying both sides by 2,

v₁² + 2gh₁ = v₂²

Therefore, the velocity of the fish when it hits the water is,

v₂ = √(v₁² + 2gh₁)

v₂ = √(20² + 2 x 9.8 x 5)

v₂ = 22.3 m/s

2) Weight of the diver, W = 740 N

Height from which the board is dropped, h = 10 m

W = mg

Therefore, mass of the diver,

m = W/g

m = 740/9.8

m = 108.82

So, the potential energy of the diver is converted into kinetic energy of the diver.

mgh + 0 = 1/2 mv²

v²= 2gh

Therefore, velocity of the diver is,

v = √2gh

v = √2 x 9.8 x 4

v = 8.85 m/s

3) Velocity of the runner, v = 2 m/s

KE = PE

1/2 mv² = mgh

v²/2 = gh

Therefore, the height to which the runner’s center of mass is raised during the jump is,

h = v²/2g

h = 2²/(2 x 9.8)

h = 0.204 m

4) Speed of the bob, v = 2.2 m/s

Initial height of the bob is,

h = v²/2g

h = (2.2)²/(2 x 9.8)

h = 0.224 m

Express your answer as an integer.
Part B
What is the angle of the bright spot farthest from the center?

Answers

The total number of bright spots (indicating complete constructive interference) is 2,The angle of the bright spot farthest from the center is approximately 0.06 degrees

Part A:

The total number of bright spots can be found using the equation:

nλ = d(sinθ + sinθ')

where n is the order of the bright spot, λ is the wavelength of light, d is the distance between adjacent slits on the grating,

θ is the angle between the incident ray and the normal to the grating, and θ' is the angle between the diffracted ray and the normal to the grating.

For maximum constructive interference, sinθ = 1 and sinθ' = 1, which gives:

nλ = d(2)

n = 2d/λ

The largest value of n occurs when sinθ is maximized, which is when θ = 90 degrees. Therefore, the maximum value of n is:

nmax = 2d/λmax

Substituting the given values, we get:

nmax = 2(1/299 mm)/631 nm

nmax ≈ 2

Part B:

The angle of the bright spot farthest from the center can be found using the equation:

dsinθ = mλ

where d is the distance between adjacent slits on the grating, θ is the angle between the incident ray and the normal to the grating, m is the order of the bright spot, and λ is the wavelength of light.

For the bright spot farthest from the center, m = 1. The maximum value of sinθ occurs when θ = 90 degrees. Therefore, we have:

dsinθmax = λ

Substituting the given values, we get:

sinθmax ≈ λ/(d*m) ≈ 0.00105

To find the current needed to produce a magnetic field of 2.0 × 10−2t within the solenoid with 12 turns per centimeter, we can use the formula for the magnetic field strength inside a solenoid:

B = μ0 * n * I

Where B is the magnetic field strength, μ0 is the permeability of free space (4π × 10−7 T•m/A), n is the number of turns per unit length (in this case, 12 turns/cm or 120 turns/m), and I is the current flowing through the solenoid.

Rearranging the formula to solve for I, we get:

I = B / (μ0 * n)

Plugging in the values we have, we get:

I = (2.0 × 10−2 T) / (4π × 10−7 T•m/A * 120 turns/m)

a star is moving away from earth at a speed of 2.400 × 108 m/s. light of wavelength 374.0 nm is emitted by the star. what is the wavelength as measured by an earth observer?

Answers

The observed wavelength of light as measured by an Earth observer is 382.3 nm.

This is slightly longer than the emitted wavelength of 374.0 nm, indicating that the star is moving away from us.

This effect, known as redshift, is caused by the Doppler effect and is used by astronomers to measure the motion of stars and galaxies relative to Earth.

The observed wavelength of light, λ', is related to the emitted wavelength of light, λ, and the relative velocity between the source and observer, v, by the formula:
λ' = λ(1 + v/c)
where c is the speed of light in vacuum.

In this case, the star is moving away from the Earth, so v = 2.400 × 108 m/s. The emitted wavelength is λ = 374.0 nm, or 374.0 × 10^-9 m. The speed of light is c = 3.00 × 10^8 m/s.

Plugging these values into the formula, we get:
λ' = λ(1 + v/c) = (374.0 × 10^-9 m)(1 + 2.400 × 10^8 m/s ÷ 3.00 × 10^8 m/s) = 382.3 nm

If Betelgeuse had a mass that was 25 times that of the Sun, how would its average density compare to that of the Sun? Use the definition of denisty= mass/volume , where the volume is that of a sphere.

Answers

To compare the average density of Betelgeuse with the Sun, given that Betelgeuse has a mass 25 times that of the Sun, we will use the density formula: density = mass/volume, where the volume is that of a sphere.



Step 1: Determine the ratio of the masses.


Since Betelgeuse has a mass 25 times that of the Sun, the mass ratio is 25:1.



Step 2: Find the ratio of the volumes.


For spheres, volume is given by the formula V = (4/3)πr³. To find the ratio of the volumes, we need to find the ratio of the radii cubed. Betelgeuse has a radius approximately 900 times that of the Sun. Therefore, the radius ratio is 900:1.



Step 3: Cube the radius ratio.


Cubing the radius ratio, we get (900³):(1³) = 729,000,000:1. This is the ratio of the volumes.



Step 4: Calculate the density ratio.


Using the mass ratio (25:1) and the volume ratio (729,000,000:1), we can find the density ratio: (density of Betelgeuse)/(density of the Sun) = (25/729,000,000).



Step 5: Simplify the density ratio.


Simplifying the density ratio, we get (1/29,160,000).



So, the average density of Betelgeuse is 1/29,160,000 times the density of the Sun. This means Betelgeuse is much less dense than the Sun.

a 78 kg man lying on a surface of negligible friction shoves a 61 g stone away from himself, giving it a speed of 2.5 m/s. what speed does the man acquire as a result

Answers

The man acquires a velocity of approximately -0.00195 m/s in the opposite direction.

What is the resulting velocity of the man when considering the momentum after shoving the stone?

To solve this problem, we can use the principle of conservation of momentum. According to this principle, the total momentum before the interaction is equal to the total momentum after the interaction.

The momentum of an object is given by the product of its mass and velocity (p = mv). Let's denote the initial velocity of the man as v_m and the final velocity of the man as v'_m. The initial velocity of the stone is 0 m/s, and its final velocity is 2.5 m/s.

The total momentum before the interaction is zero since the stone is initially at rest:

Initial momentum = m_man * v_man + m_stone * v_stone = 78 kg * v_man + 0 kg * 0 m/s = 78 kg * v_man

The total momentum after the interaction is the sum of the individual momenta of the man and the stone:

Final momentum = m_man * v'_man + m_stone * v'_stone = 78 kg * v'_man + 0.061 kg * 2.5 m/s

Since the total momentum is conserved, we can equate the initial and final momenta:

78 kg * v_man = 78 kg * v'_man + 0.061 kg * 2.5 m/s

Now we can solve for v'_man, which is the final velocity of the man:

78 kg * v_man - 0.061 kg * 2.5 m/s = 78 kg * v'_man

78 kg * v'_man = 78 kg * v_man - 0.061 kg * 2.5 m/s

v'_man = (78 kg * v_man - 0.061 kg * 2.5 m/s) / 78 kg

Plugging in the values, we have:

v'_man = (78 kg * v_man - 0.061 kg * 2.5 m/s) / 78 kg

Since the man is initially at rest (v_man = 0 m/s), we can simplify the equation to:

v'_man = (0 - 0.061 kg * 2.5 m/s) / 78 kg

v'_man = -0.1525 m/s / 78 kg

v'_man ≈ -0.00195 m/s

Therefore, the man acquires a velocity of approximately -0.00195 m/s in the opposite direction as a result of shoving the stone.

A spherical hot air balloon inflates at a rate of 101 ft3/min. At what rate is the radius changing when the surface area is Selected values for h(t) are shown in the table. Let f(x)= 1:"h(t)dt. Find f'(4). 4 h(t)1 3 1 2 The position function of a particle moving horizontally along the x-axis is given by x(t)sin (3t -2) + t. Find the initial velocity of the particle.

Answers

The initial velocity of the particle is approximately 3.832 units.

To address your question, we will first focus on the spherical hot air balloon inflating at a rate of 101 ft³/min and find the rate at which the radius is changing when the surface area is given. Then, we'll find the initial velocity of the particle moving horizontally along the x-axis.

For the hot air balloon:

1. The volume of a sphere is V = (4/3)πr³.
2. The surface area of a sphere is A = 4πr².

Given: dV/dt = 101 ft³/min.

We want to find dr/dt when A is given. First, we need to find the relationship between V and A:

V = (A³)/(108π²).

Now differentiate V with respect to time (t):

dV/dt = d(A³/108π²)/dt.

Since dV/dt is given as 101, we have:

101 = 3A²dA/dt/108π².

Now, we can find dA/dt when the surface area A is given, and then use the relationship between A and r (A = 4πr²) to find dr/dt.

For the particle moving along the x-axis:

Given: x(t) = sin(3t - 2) + t.

Velocity is the first derivative of position with respect to time:

v(t) = dx/dt = cos(3t - 2) × 3 + 1.

To find the initial velocity, evaluate v(t) at t = 0:

v(0) = cos(3 × 0 - 2) × 3 + 1 = cos(-2) × 3 + 1 ≈ 3.832.

So, the initial velocity of the particle is approximately 3.832 units.

a hall probe gives a reading of 1.5 μv for a current of 2 a when it is placed in a magne5c field of 1 t. what is the magne5c field in a region where the reading is 2μv for 1.7 a of current?

Answers

The magnetic field in the region where the hall probe gives a reading of 2μV for 1.7A of current is 1.78T.

The magnetic field in a region where the hall probe gives a reading of 2μV for 1.7A of current can be calculated as 1.7/2 times the magnetic field in the region where the reading is 1.5μV for 2A of current.

First, we can use the formula B = (V/I)/(1/RH) where B is the magnetic field, V is the voltage reading, I is the current, and RH is the Hall coefficient of the probe.

In the first region, B₁ = (1.5 μV/2A)/(1/RH)

In the second region, B₂ = (2 μV/1.7A)/(1/RH)

We can rearrange the equations to solve for RH and set them equal to each other:

RH = (1.5 μV/2A) / B₁ = (2 μV/1.7A) / B₂

Solving for B₂, we get:

B₂ = (2 μV/1.7A) / [(1.5 μV/2A) / B₁] = 1.78T

Contextual interference is interference introduced into the practice session through the use of massed practice schedule. (T o F)

Answers

The given statement "Contextual interference is interference introduced into the practice session through the use of massed practice schedule" is FALSE because it introduced into the practice session through the use of varied or random practice schedules, not massed practice schedules.

It is a phenomenon where learning is more challenging due to the mixing of various skills, but it often leads to better long-term retention and skill transfer.

Massed practice, on the other hand, involves repetitive practice of a single skill in a short amount of time without introducing variations, which can sometimes lead to quicker short-term improvements but may not enhance long-term retention as effectively as varied practice schedules.

What is the absolute magnitude of the reduction in the variation of Y when times is introduced into the regression model? What is the relative reduction? What is the name of the latter measure?

Answers

1. The absolute magnitude of the reduction in variation of Y when time is introduced into the regression model can be calculated by subtracting the variance of Y in the original model from the variance of Y in the new model.

2. The relative reduction can be calculated by dividing the absolute magnitude by the variance of Y in the original model.

3. The latter measure is called the coefficient of determination or R-squared and represents the proportion of variance in Y that can be explained by the regression model.

When time is introduced into a regression model, it can have an impact on the variation of the dependent variable Y. The absolute magnitude of this reduction in variation can be measured by calculating the difference between the variance of Y in the original model and the variance of Y in the new model that includes time. The relative reduction in variation can be calculated by dividing the absolute magnitude of the reduction by the variance of Y in the original model.
The latter measure, which is the ratio of the reduction in variation to the variance of Y in the original model, is called the coefficient of determination or R-squared. This measure represents the proportion of the variance in Y that can be explained by the regression model, including the independent variable time. A higher R-squared value indicates that the regression model is more effective at explaining the variation in Y.

Answers

The answer for A 8.0-cm radius disk with a rotational inertia is A. 0.50 m/s^2, which is less than 1 g.

To solve this problem, we can use the equation τ = Iα, where τ is the torque applied, I is the rotational inertia, and α is the angular acceleration.
First, we need to find the angular acceleration. We know that the torque applied is 9.0 N·m and the rotational inertia is 0.12 kg·m^2, so we can plug these values into the equation and solve for α:
τ = Iα
9.0 N·m = 0.12 kg·m^2 α
α = 75 rad/s^2
Next, we need to find the linear acceleration of the mass. We can use the equation a = rα, where a is the linear acceleration, r is the radius of the disk, and α is the angular acceleration we just found:
a = rα
a = 0.08 m × 75 rad/s^2
a = 6.0 m/s^2
Finally, we need to divide the linear acceleration by the acceleration due to gravity to get the answer in terms of g's:
a/g = 6.0 m/s^2 / 9.81 m/s^2 ≈ 0.61 g's

A cylindrical copper rod has resistance R. It is reformed into a cylinder that has a length three times its original length with no change of volume (Note: Volume = Length * Area). Its new resistance is: O R/3 9R d 3R 0 R/9 OR

Answers

The area is reduced by 1/3, the resistance will increase by a factor of 3. Therefore, the new resistance is 3R * 3 = 9R.

The resistance of a conductor is given by the formula R = ρ (L/A), where ρ is the resistivity, L is the length, and A is the cross-sectional area. Since the volume remains the same, the product of length and area should remain constant. When the length is tripled, the cross-sectional area must be reduced by a factor of 1/3 to maintain the volume. The resistance is inversely proportional to the cross-sectional area, so if the area is reduced by 1/3, the resistance will increase by a factor of 3. Therefore, the new resistance is 3R * 3 = 9R.

Answers

If a monopolist is regulated to charge an efficient price, there would be no deadweight loss (DWL) as the price and quantity produced would be the same as in a perfectly competitive market. Therefore, the answer is (a) zero.

In market, the price is equal to the marginal cost (MC) of production, which represents the efficient price.

In a monopoly market, the price is set where marginal revenue (MR) equals marginal cost (MC), which is always higher than the efficient price.

If the regulator sets the price at the efficient level, the monopolist will produce at the same quantity as a perfectly competitive market, and there will be no DWL. Therefore, the answer is (a) zero.

the end point of a spring oscillates with a period of 3.8 s when a block with mass m is attached to it. when this mass is increased by 1.8 kg, the period is found to be 8.6 s. a)find m=?b) find spring constant(k)=?

Answers

The initial mass m is approximately 2.2 kg, and the spring constant k is approximately 10.8 N/m.

To solve this problem, we'll use the formula for the period of a spring-block system:

T = 2π√(m/k)

where T is the period, m is the mass, and k is the spring constant. 1)

For the initial mass m, T1 = 3.8 s. So, 3.8 = 2π√(m/k). 2)

For the increased mass (m + 1.8 kg), T2 = 8.6 s.

So, 8.6 = 2π√((m + 1.8)/k).

We have two equations and two unknowns (m and k).

To find m, we can first solve for k in equation 1:

k = (2πm/3.8)².

Now, substitute this expression for k in equation 2:

8.6 = 2π√((m + 1.8)/((2πm/3.8)²))

Solving for m, we get m ≈ 2.2 kg.

Next, find the spring constant k using the expression for k from equation 1:

k ≈ (2π(2.2)/3.8)² ≈ 10.8 N/m.
