The displacement of the ball is zero.

What is displacement?

The smallest distance between the initial and final position of an object.

What are the equations of motion?

There are three equations of motion that completely describes the motion of an object.

The first equation of motion gives the relationship between the initial velocity, final velocity, acceleration, and time.

The second equation of motion gives the relationship between the initial velocity, displacement, acceleration, and time.

The third equation of motion gives the relationship between the initial velocity, final velocity, acceleration, and displacement.

Given time, initial velocity, and acceleration, the displacement can be calculated using the second equation of motion. The second equation of motion is,

s=u*t+(1/2)*a*t^2

Here, u=25 m/sec, a=-25 m/sec and t=2.0 sec.

Put the values in the formula and calculate the displacement.

s= (25)*(2.0)+(1/2)*(-25)*(2.0)^2

s=50-50

The change in mass during the chemical reaction is not likely to be detectable since it is extremely small compared to the initial masses of hydrogen and oxygen. The mass remains conserved during chemical reactions.

Given data:When 1.00g of hydrogen combines with 8.00g of oxygen, 9.00g of water is formed. During this chemical reaction, 2.86 × 105J of energy is released.(c) Explain whether the change in mass is likely to be detectable.During the chemical reaction, hydrogen combines with oxygen to form water molecule.

The mass of hydrogen is 1.00 g and that of oxygen is 8.00 g. The sum of the mass of hydrogen and oxygen = 1.00 g + 8.00 g = 9.00 gThe reaction product is water, whose mass is 9.00 g. Thus, the mass of the reaction product equals the sum of the masses of the reactants. Therefore, there is no change in mass.

Hence, the change in mass is not likely to be detectable during the chemical reaction.An explanation of this observation is provided by the law of conservation of mass. According to this law, the total mass of reactants is equal to the total mass of products. As the number of atoms is conserved during the chemical reaction, the mass of the reactants must be equal to the mass of the products. Thus, the mass remains conserved during chemical reactions.

FALSE. The total weight of a multistage rocket does not greatly reduce as the rocket lands.

Multistage rockets are designed to shed weight as they ascend into space, not as they land. A multistage rocket consists of multiple stages stacked on top of each other, with each stage having its own engines and fuel supply.

Typically, the lower stages are jettisoned once their fuel is depleted, reducing the weight of the rocket as it ascends.

However, during the landing phase, the rocket needs to decelerate and land safely. This requires additional fuel and systems, such as landing legs or thrusters, to control the descent. These components add weight to the rocket during the landing phase.

Therefore, (False) the total weight of a multistage rocket does not greatly reduce as the rocket lands. It is essential to have sufficient fuel reserves and structural integrity to ensure a controlled landing and ensure the safety of the mission.

The de Broglie wavelength of the alpha particle is approximately 3.76 × 10^(-12) meters.

To find the de Broglie wavelength of an alpha particle, we can use the de Broglie wavelength equation:

λ = h / p

Where:

- λ is the de Broglie wavelength

- h is the Planck's constant (approximately \(6.626 × 10^(-34) m^2 kg / s)\)

- p is the momentum of the particle

Given:

- Mass of the alpha particle (m) =\(6.64 × 10^(-27) kg\)

- Energy of the alpha particle (E) = 4.23 MeV (convert to Joules by multiplying by \(1.6 × 10^(-13)\) Joules/MeV)

First, we need to find the momentum of the alpha particle. We can use the relativistic equation for momentum:

\(p = sqrt(2 * m * E)\)

Substitute the values into the equation:

\(p = sqrt(2 * (6.64 × 10^(-27) kg) * (4.23 × 1.6 × 10^(-13) Joules))\)

Calculate the value of p.

\(p ≈ 1.76 × 10^(-22) kg m/s\)

Now, we can calculate the de Broglie wavelength using the obtained momentum.

\(λ = h / p = (6.626 × 10^(-34) m^2 kg / s) / (1.76 × 10^(-22) kg m/s)\)

There isn't enough information included in the picture to fill in any of the missing items for the other two resistors.

It will take 2.857 minutes (or about 2 minutes and 51 seconds) for the fish to reach a temperature of 60 °C.

To determine the time it will take for the fish to reach a temperature of 60 °C, we can use the principle of heat conduction and the concept of temperature difference.

We know that the rate of heating by conduction is proportional to the temperature difference between the body and its surroundings. Therefore, we can write the following equation:

(T - Ts) = k * t

where T is the temperature of the fish, Ts is the temperature of the surroundings (boiling water), k is the proportionality constant, and t is the time.

Given that the initial temperature of the fish is 20 °C and it takes 5 minutes to reach 30 °C, we can substitute these values into the equation:

(30 - 100) = k * 5

-70 = 5k

Solving for k, we find k = -14.

Now we can use this value of k to find the time it will take for the fish to reach 60 °C:

(60 - 100) = -14 * t

-40 = -14t

Dividing both sides by -14, we get t = 2.857 minutes.

More length of a wire is a component that has a greater resistance as the current through it increases​.

The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions present in the wire as they pass through. The moving electrons can collide with the ions present in the metal.

This makes more difficult for the current to flow and causes resistance in the wire so we can conclude that more length of a wire is a component that has greater resistance as more current passes through it.

To find the maximum speed the car can travel without slipping, you can use the formula:

v = sqrt(μ * g * r)

where v is the maximum velocity, μ is the coefficient of friction, g is the acceleration due to gravity (9.8 m/s^2), and r is the radius of the turn.

Plugging in the given values, you get:

v = sqrt(0.60 * 9.8 m/s^2 * 75 m) = sqrt(45.9 m^2/s^2) = 6.8 m/s

So the maximum speed the car can travel without slipping is approximately 6.8 m/s.

It's important to note that this formula assumes that the car is following a circular path around the turn and that the friction force is the only force acting on the car. If either of these conditions is not met, the actual maximum speed may be slightly different.

Which states that the temperature of the gas remains constant during an isothermal process. D) assume that the temperature of the gas remains constant

The first law of thermodynamics states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system. For an ideal gas undergoing an isothermal process, the temperature remains constant. This means that the internal energy of the gas also remains constant, as the internal energy of an ideal gas is directly proportional to its temperature. Therefore, option A is incorrect.

During an isothermal process, the temperature of the gas is held constant, which means that the ideal gas law (PV = nRT) reduces to PV = constant. This means that the product of pressure and volume of the gas remains constant. Therefore, option B and option C are also incorrect.

The idea behind IMC is to design a controller by incorporating an internal model of the process dynamics. For the given process transfer function, PID controller parameters can be derived using the IMC approach.

Internal Model Control (IMC) is a control approach developed in the 1980s that aims to improve the performance of feedback control systems. It involves designing a controller that includes a model of the process being controlled, allowing for better compensation and faster response to disturbances.

Using the IMC approach, the parameters of a Proportional-Integral-Derivative (PID) controller can be derived.

To derive the PID controller parameters using the IMC approach for a given process transfer function G(s) =\(Ke^(^-^s^T^S) / (s + 1)\), the following steps can be followed:

1. Identify the process dynamics: Analyze the process transfer function to understand its behavior and dynamics. In this case, the process transfer function represents a first-order system with a time constant of T and a gain of K.

2. Select the desired closed-loop transfer function: Determine the desired closed-loop transfer function based on the performance requirements. This involves selecting appropriate values for the closed-loop time constant and damping ratio.

3. Calculate the controller parameters: Using the IMC approach, the controller parameters can be calculated based on the desired closed-loop transfer function. This involves determining the model transfer function that matches the desired closed-loop response and deriving the controller parameters from it.

In summary,By comparing the simulation results obtained using the IMC approach with another controller design method of choice, it is possible to evaluate the effectiveness and performance of the IMC approach in achieving the desired control objectives. This allows for an assessment of the advantages and disadvantages of using IMC in different scenarios.
