The car shall not be successful since the corner must have a radius as nine times as the real corner designed for a suggested speed of 15 miles per hour.

By definition of centripetal acceleration, the square of the velocity taken by the vehicle (\(v\)), in miles per hour, is directly proportional to the radius of the corner (\(R\)), in meters. Then, we have the following relationship:

\(\frac{v_{A}^{2}}{R_{A}} = \frac{v_{B}^{2}}{R_{B}}\) (1)

Where:

If we know that \(v_{A} = 15\,\frac{mi}{h}\), \(v_{B} = 45\,\frac{mi}{h}\) and \(R_{A} = k\), then the expected radius of the corner is:

\(R_{B} = k\cdot \left(\frac{v_{B}}{v_{A}} \right)^{2}\)

\(R_{B} = 9\cdot k\)

In order to successfully take a corner at 45 miles per hour, the corner must have a radius as nine times as the real corner designed for a suggested speed of 15 miles per hour. Thus, the car shall not be successful at a speed of 45 miles per hour.

Answer:

The correct answer is when the slope is steep.

Explanation:

The advancement of water inland is dependent on the rate at which water wears off the continental shelf and the coastal plain. The higher the amount of rainfall, and the harshness of the dry spells, the faster the rate of erosion that occurs at the coastal plain.

As the erosion increases, the coastal plain becomes steeper. The steeper the plain, the water flowing erodes the coastal plain at a faster rate. Hence the water advances farther inland faster than where the slope is gentle or gradual.

The T tubules, or transverse tubules, are essential structures within muscle fibers that play a crucial role in the process of muscle contraction.

The main function of the T tubules is to transmit the action potential, or electrical impulse, deep into the muscle fiber. When a signal is initiated in the motor neuron, it travels along the nerve fiber and reaches the neuromuscular junction, where it triggers the release of neurotransmitters. These neurotransmitters bind to receptors on the muscle fiber's surface, initiating an action potential. The action potential then rapidly spreads along the T tubules, reaching the interior of the muscle fiber.

The released calcium ions diffuse into the surrounding myofibrils, specifically the sarcomeres, which are the functional units of muscle contraction. The presence of T tubules ensures that the action potential reaches deep into the muscle fiber, allowing for a coordinated and synchronized contraction of all the sarcomeres within the muscle. This ensures efficient and effective muscle function.

Answer:

I think It is D

Explanation:

The diffusion of phosphorus atoms into a silicon wafer involves a predeposition treatment at 950°C for 50 minutes, surface concentration of P at 2.0 x 10^26 atoms/m^3, followed by a drive-in diffusion at 1200°C for 3.0 hours.

To calculate the depth of diffusion (x) during the predeposition and drive-in treatments, we can use the equation:

x = sqrt((4 * D * t) / π)

where x is the depth of diffusion, D is the diffusion coefficient, and t is the time.

Predeposition Treatment:

Given:

Temperature (T) = 1223 K

Time (t) = 3000 seconds

Surface concentration (Cs) = 2.0 x 10^26 atoms/m^3

According to the diffusion coefficient (D)  formula:

D =( D0 * exp(-Q d / (k * T)))

where D0 is the pre-exponential factor, Qd is the activation energy, and k is the Boltzmann constant (8.617 x 10^-5 eV/K).

Substituting the values and calculating D:

D = (1.1 x 10^4 m^2/s) * exp(-3.40 eV / (8.617 x 10^-5 eV/K * 1223 K))

D ≈ 3.32 x 10^-4 m^2/s

Now, substitute the values into the depth of diffusion formula:

x = sqrt((4 * D * t) / π)

x = sqrt((4 * (3.32 x 10^-4 m^2/s) * 3000 s) / π)

x ≈ 0.029 m or 29 mm

Therefore, during the predeposition treatment, the depth of diffusion is approximately 29 mm.

Drive-In Diffusion:

Given:

Temperature (T) = 1200°C = 1473 K

Time (t) = 3.0 hours = 3.0 * 60 * 60 = 10800 seconds

Using the same diffusion coefficient (D) calculated earlier, we can calculate the depth of diffusion (x) during the drive-in treatment:

x = sqrt((4 * D * t) / π)

x = sqrt((4 * (3.32 x 10^-4 m^2/s) * 10800 s) / π)

x ≈ 0.135 m or 135 mm

Therefore, during the drive-in diffusion, the depth of diffusion is approximately 135 mm.

During the predeposition treatment, the depth of diffusion of phosphorus (P) atoms into the silicon (Si) wafer is approximately 29 mm. During the drive-in diffusion, the depth of diffusion is approximately 135 mm. These calculations are based on the given diffusion parameters and treatment conditions.

The vertical launch of kinematics allows to find the flight time of the kangaroo is

             t = 2.2 s

Given parameters

To find

Vertical launch is an application of kinematics where there is no motion on the ax axis and on the y axis the acceleration is the acceleration of gravity (g = 32.16 ft / s²), the equation of motion is

               y = y₀ + v₀ t - ½ g t²

The expression written in the exercise has some typing errors.  Where y and y₀ are the current and initial height, respectively, v₀ the initial velocity, g the acceleration of gravity and t the time

The time of flight occurs when the kangaroo reaches the ground (y = 0)

              0 = 0 + v₀ t - ½ g t²

              t (v₀ - ½ g t) = 0

This expression has two solutions

             t = 0 s

This solution corresponds to the time of departure and the solution for the time of arrival on the ground is

             t = \(\frac{2v_o}{g}\)

             t = 2 36 / 32.16

            t = 2.24 s

Using the proposed criterion of leaving a single decimal the answer is

              t = 2.2 s

In conclusion with the vertical launch of kinematics we can find the flight time of the kangaroo is

             t = 2.2 s

Answer:

400 kN

Explanation:

El principio de Arquímedes establece que, cuando un cuerpo está total o parcialmente sumergido en un fluido, experimenta un empuje hacia arriba que es igual al peso del fluido desplazado.

Dado que;

Volumen del bloque = 80m ^ 3

Densidad del agua = 1000 kg / m ^ 3

Empuje hacia arriba = 1/2 * 80 * 1000 * 10

Empuje hacia arriba = 400 kN

Amy's distance is 800 meters since she runs 2 laps around the 400 meter track. Her displacement is 0 meters because displacement refers to the change in position from the starting point to the end point, and since she ends up back where she started, the displacement is zero.

Distance refers to the total length covered in a particular path, regardless of direction or position. Amy runs 2 laps, and each lap is 400 meters, so her total distance is 800 meters (400 meters per lap multiplied by 2 laps).

Displacement, on the other hand, refers to the change in position from the starting point to the end point. Since Amy ends up back at the starting point after completing her 2 laps, her displacement is zero. Displacement takes into account direction and position, and in this case, there is no net change in position from the start to the end, resulting in a displacement of zero.

If one element of a series circuit fails, current ceases to flow completely is accurate.

A circuit is a closed conduct for electricity to travel through and is made up of parts like wires, resistors, capacitors, and transistors that regulate the flow of energy.

The components of a series circuit are connected in a line, the current passes through each one in turn. A broken circuit results from one component failing or being open, which stops the electricity from flowing at all. This is because a series circuit only has one path for the current to go, so if one component breaks down, the circuit as a whole is disturbed.

However, the first claim that series circuits are typically far more difficult to construct than straightforward parallel circuits is untrue. Series circuits just need components connected in a straight line, making them comparatively easy to build. It is also true that in a series circuit, electrons can only flow in one direction.

The table exerts an upward force on the book, which is equal in magnitude and opposite in direction to the force of gravity pulling the book downward force. This is known as the normal force.

When a book is resting on a table, the table exerts an upward force on the book, known as the normal force. This force is perpendicular to the surface of the table and prevents the book from falling through the table. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. So, the book exerts a downward force on the table, but this force does not cause any motion as it is balanced by the normal force exerted by the table on the book. Therefore, the net force on the book is zero, and it remains at rest on the table.

It is possible for a heat engine to receive 500 kJ/s of heat from an 1100-K source and reject 300 kJ/s to a low-temperature sink at 300 K. This scenario is in accordance with the second law of thermodynamics, which states that heat naturally flows from a higher temperature to a lower temperature.

The net rate of change of entropy for this system can be calculated using the equation ΔS = Q_in / T_in - Q_out / T_out, where ΔS is the change in entropy, Q_in is the heat received, Q_out is the heat rejected, T_in is the temperature of the heat source, and T_out is the temperature of the heat sink. The thermal efficiency of a heat engine is given by the formula η = (W_out / Q_in) * 100%, where η is the efficiency, W_out is the work output, and Q_in is the heat input. The maximum efficiency that a heat engine can achieve is given by the Carnot efficiency, which is determined solely by the temperatures of the heat source and heat sink.
