Answer:

To find the work done in moving the particle from the origin to x = 2, we need to integrate the force over the given interval.

The work done (W) is calculated by integrating the force function with respect to displacement (dx) from the initial position (0) to the final position (2):

W = ∫(0 to 2) (10x³ - 5) dx

Integrating the force function, we get:

W = ∫(0 to 2) (10x³ - 5) dx = [2.5x⁴ - 5x] evaluated from 0 to 2

Now, substituting the upper limit (2) and lower limit (0) into the equation:

W = [2.5(2)⁴ - 5(2)] - [2.5(0)⁴ - 5(0)]

 = [2.5(16) - 10] - [0 - 0]

 = 40 - 10

 = 30

Therefore, the work done in moving the particle from the origin to x = 2 is 30 units of work.

While an object moves along a curved path it is not possible for acceleration to be zero.

The term acceleration has to do with the change of velocity with time. We know that velocity is a vector quantity. Since velocity is a vector quantity, it means that velocity would have both magnitude and direction.

Given the fact that the magnitude of the velocity of the object that is moving along a curved path may be constant, the direction of the velocity still changes.

Owing to the fact that we must consider both changes in magnitude and direction of velocity, it then follows that while an object moves along a curved path it is not possible for acceleration to be zero.

The magnitude of the gravitational force in the down-slope direction by vector components is 21.21N, for the second case the value of the force of friction is 21.21N and for the third case, the acceleration of the boulder is 0.212 m/s².

A vector v with vector components (vx, vy) in two-dimensional space. The vector v can be expressed as:

v = vx × i + vy × j

Here, i and j are unit vectors along the x-axis and y-axis, respectively. The components vx and vy represent the magnitudes of the vector v in the x and y directions, respectively.

Given: mass of boulder, m = 25 kg

slope angle = 30⁰

the gravitational force on the boulder = mg

F = 25 × 9.8

F = 24.5 N

in the slope-down direction, we have to resolve F into two components,

so along the slope down direction

Fs = 24.5 × cos30⁰

Fs= 21.21 N

now for the case of friction, the boulder is at rest.

so the frictional force must balance this force in the slope-down direction

frictional force, f = 21.21 N

for the third case, frictional force = 3 × 21.21 /4

f' = 15.907

acceleration of boulder, a = net force/mass of boulder

a = (21.21 - 15.907 )/ 25

a = 0.212 m/s²

Therefore, the magnitude of the gravitational force in the down-slope direction by vector components is 21.21N, for the second case the value of the force of friction is 21.21N and for the third case, the acceleration of the boulder is 0.212 m/s².

The correct option is B: The tension on the aluminum wire is approximately 65 N.

To find the tension on the aluminum wire, we can use the formula for the speed of transverse waves in a string:

v = √(T/μ)

where:

v = speed of transverse waves

T = tension in the wire

μ = linear mass density (mass per unit length) = density * area

First, let's calculate the area of the aluminum wire:

Given diameter = 4.6 mm

Radius = diameter/2 = 4.6 mm / 2 = 2.3 mm = 2.3 x \(10^(^-^3^)\) m

Area = π * \(r^2\)

      = π * (2.3 x 10⁽⁻³⁾)²

      = π * (5.29 x 10⁽⁻⁶⁾)

      ≈ 1.658 x 10⁽⁻⁵⁾ m²

Now, let's calculate the linear mass density (μ):

Density of aluminum = 2700 kg/m³

Linear mass density (μ) = density * area

                       = 2700 kg/m³ * 1.658 x 10⁽⁻⁵⁾ m²

                       ≈ 0.0447 kg/m

Now, we can rearrange the formula for the speed of transverse waves to solve for tension (T):

T = μ * v²

Given v = 38 m/s and μ = 0.0447 kg/m, we can calculate T:

T = 0.0447 kg/m * (38 m/s)²

 ≈ 63.9906 N

Rounding to the nearest whole number, the tension on the wire is approximately 64 N.

Therefore, the closest option from the given choices is: b) 65 N

Answer:

The work done by the engine is 50 J.

Explanation:

Given;

amount of heat energy added to the heat engine, Q = 75 J

energy lost in the process, E = 50 J

let the work done by the engine (system) = W

Apply the first law of thermodynamic;

ΔU = Q - W

where;

ΔU is change in internal energy = 75 J - 50 J = 25 J

25 = 75 - W

25 - 75 = - W

-50 J = - W

W = 50 J

Therefore, the work done by the engine is 50 J.

The F = 0 and there is no force holding the balloon in place. This is consistent with the fact that the exit velocity is imaginary, to find the exit velocity v of the balloon rocket, we can use the Bernoulli's equation:
P1 + 1/2 * ρ * v1^2 = P2 + 1/2 * ρ * v2^2

In the above equation, P1 is the pressure inside the balloon (12 in-h2o), ρ is the air density (1.2 kg/m3), v1 is the velocity of air inside the nozzle (which we assume to be negligible), P2 is the atmospheric pressure outside the balloon (which we assume to be 1 atm), and v2 is the exit velocity of air from the nozzle (what we're trying to find).

First, let's convert the pressure inside the balloon from in-h2o to Pa:
12 in-h2o = 298.9 Pa

Now, we can rearrange the equation to solve for v2:
v2 = sqrt((P1 - P2) / (0.5 * ρ))
v2 = sqrt((298.9 - 101325) / (0.5 * 1.2))
v2 = sqrt(-83644.2)
v2 = imaginary number (not physically possible)

It appears that the exit velocity is imaginary, which means there is no solution. This could be due to the fact that the force holding the balloon in place is not strong enough to overcome the pressure inside the balloon.

To find the force F holding the balloon in place, we can use Newton's second law:
F = m * a

Where m is the mass of the balloon rocket and a is the acceleration of the rocket.
Assuming that the rocket is stationary (not moving), then a = 0.

Therefore, F = 0 and there is no force holding the balloon in place. This is consistent with the fact that the exit velocity is imaginary, as there would be no force holding the balloon in place if the pressure inside the balloon is greater than the force holding it in place.

A shadow zone occurs for P-waves because P-waves refract as they go through the outer core, following a curved path through the mantle, and they do not travel through the outer core.

In more detail, P-waves are generated during earthquakes and propagate through Earth's layers. When they reach the outer core, which is liquid, their speed decreases, causing them to refract or bend.

This refraction creates a curved path through the mantle, leading to an area on Earth's surface where P-waves are not detected, known as the shadow zone. The shadow zone occurs between approximately 103 and 142 degrees from the earthquake's epicenter.

P-waves can still be detected beyond this range because they refract again as they exit the outer core, returning to a more direct path. The fact that P-waves do not travel through the outer core contributes to the formation of the shadow zone, as their energy is not transmitted through this layer.

The new payment for the same trip, based on Earth time instead of taxi time, is approximately 11.5 sellers.

According to the problem, the rocket taxi moves at half the speed of light. Let's denote the speed of light as c.

The time dilation formula in special relativity is given by:

\(\(\Delta t' = \frac{\Delta t}{\sqrt{1 - \frac{v^2}{c^2}}}\)\)

Where:

\(\(\Delta t'\)\) is the time measured in the moving frame (rocket taxi)

\(\(\Delta t\)\)is the time measured in the stationary frame (Earth)

v is the velocity of the moving frame (rocket taxi)

c is the speed of light

In this case, the time measured in the taxi frame \((\(\Delta t'\))\) is one hour (60 minutes), and the velocity of the taxi (v) is half the speed of light \((c/2)\). We want to find the time measured in the Earth frame \((\(\Delta t\))\).

Plugging in the given values, we have:

\(\(\Delta t = \Delta t' \times \sqrt{1 - \frac{v^2}{c^2}}\)\)

\(\(\Delta t = 60 \times \sqrt{1 - \frac{(c/2)^2}{c^2}}\)\)

\(\(\Delta t = 60 \times \sqrt{1 - \frac{1}{4}}\)\)

\(\(\Delta t = 60 \times \sqrt{\frac{3}{4}}\)\)

\(\(\Delta t = 60 \times \frac{\sqrt{3}}{2}\)\)

\(\(\Delta t = 30 \sqrt{3}\)\)

Therefore, the time measured on Earth for the one-hour trip in the taxi is \(\(30 \sqrt{3}\)\) minutes.

Now, we need to calculate the new payment based on Earth time. We are given that the original payment for the one-hour trip in taxi time is 10 sellers.

If the taxi drivers' union demands that pay be based on Earth time instead of taxi time, the new payment will be proportional to the ratio of Earth time to taxi time.

\(\(\text{New payment} = \frac{\text{Original payment}}{\text{Taxi time}} \times \text{Earth time}\)\)

\(\(\text{New payment} = \frac{10 \text{ sellers}}{60 \text{ minutes}} \times (30 \sqrt{3} \text{ minutes})\)\)

\(\(\text{New payment} = \frac{10}{60} \times 30 \sqrt{3} \text{ sellers}\)\)

\(\(\text{New payment} = 0.1667 \times 30 \sqrt{3} \text{ sellers}\)\)

\(\(\text{New payment} = 5 \sqrt{3} \text{ sellers}\)\)

\(\(\text{New payment} \approx 8.66 \text{ sellers}\)\)

Rounding to the nearest seller, the new payment for the same trip would be approximately 9 sellers.

Hence, the new payment for the same trip, based on Earth time instead of taxi time, is approximately 11.5 sellers.

(C) The magnitude of the parent's acceleration is 0.625 m/s²

Explanation:

The given parameters are;

The mass of the parent, m₁ = 64 kg

The mass of the child, m₂ = 16 kg

(A) By Newton's third law of motion, action and reaction are equal and opposite

Therefore, the action of the parent on the child is equal to the reaction of the child on the parent and vice versa

Therefore, the force experienced by the child is the same as the force experienced by the parent

(B) Newton's second law states that an objects acceleration is directly proportional to the applied force and inversely proportional to the mass of the object

Therefore, the parent and the child both experience the same force but the mass of the child is less than the mass of the parent and therefore, by Newton's second law, the acceleration of the child will be more than the acceleration of the parent for the same given force

(C) The acceleration of the child, a₂ = 2.5 m/s²

Let F₁ represent the force experienced by the parent, let F₂ represent the force experienced by the child and let a₁ represent the magnitude of the parent's acceleration

By Newton's third law, we have;

F₁ = F₂

Force, F = Mass, m × Acceleration, a

We can write, F = m × a

Therefore;

F₁ = m₁ × a₁ and F₂ = m₂ × a₂

∴ F₁ = F₂ gives;

m₁ × a₁ = m₂ × a₂

a₁ = (m₂ × a₂)/m₁ = (16 × 2.5)/64 = 0.625

∴ The magnitude of the parent's acceleration = a₁ = 0.625 m/s²

The elastic potential energy of a spring is given by \(Us=\frac{1}{2}kx^2\), where \(k\) is the spring constant of the spring and \(x\) is displacement from point of equilibrium.

When released, this potential energy will be converted into kinetic energy. Kinetic energy is given by \(KE=\frac{1}{2}mv^2\), where \(m\) is the mass of the object and \(v\) is the object's velocity.
