Plugging the values given we have:

Therefore the answer is B.

The speed of the electron, after it has accelerated for 10^-9 seconds, is 10^5 m/s. The correct option is C.

Acceleration is the rate at which an object changes its velocity with respect to time. It is a vector quantity, which means it has both magnitude and direction. Mathematically, acceleration is defined as the change in velocity divided by the time taken for that change to occur.

Given:

Acceleration of the electron, a = F/m = 10^-14 N / 9.1 x 10^-31 kg = 1.0989 x 10^17 m/s^2

Time for which electron is accelerated, t = 10^-9 s

Using the equation, âv = at, where âv is the change in velocity, we get:

âv = at = 1.0989 x 10^17 m/s^2 x 10^-9 s = 1.0989 x 10^8 m/s

Therefore, the speed of the electron after it has accelerated for the 10^-9 second is approximately 10^8 m/s, which is closest to option (C) 10^5 m/s.

Direction of the current: Clockwise (when viewed from above).

When a magnet is dropped through a copper pipe (conductor), the motion of the magnet relative to the conductor induces an electric current due to electromagnetic induction. According to Lenz's law, the induced current will create a magnetic field that opposes the change in the magnetic field produced by the falling magnet.

In this case, if the south (S) pole of the magnet is toward the bottom, the induced current in the copper pipe will flow in a clockwise direction (when viewed from above) to create a magnetic field that opposes the motion of the falling magnet.

The induced magnetic field produced by the current in the pipe interacts with the magnetic field of the falling magnet. This interaction results in a force known as the magnetic braking force, which opposes the force of gravity acting on the magnet. As a result, the magnetic braking force reduces the acceleration of the falling magnet, causing it to fall more slowly. The energy of the falling magnet is converted into electrical energy in the form of the induced current, leading to a gradual decrease in the magnet's speed.

Answer:

His first law states that unless it is forced to change its state through external force, every object will remain stationary or move in a straight line at a constant speed. It is usually taken as the definition of inertia.

Explanation:

Therefore, the final velocity of the train when the nose leaves the station is 27.4 m/s. Therefore, the nose of the train is in the station for 4.32 seconds. Therefore, the velocity of the end of the train as it leaves the station is 20.5 m/s. Therefore, the end of the train leaves the station after 15.74 seconds.

The primary indication of an object's position and speed is its velocity. It is defined as the distance traveled by an item in one unit of time. The displacement of an item in unit time is defined as velocity. The directional speed of an item in motion as an indicator of its rate of change in position as perceived from a certain frame of reference and measured by a specific standard of time (e.g., 60 km/h northbound) is known as velocity. Simply put, velocity is the rate at which something travels in a certain direction. For example, the speed of a car driving north on a highway or the speed of a rocket after launch.

Here,

(a) To find the final velocity of the train when the nose leaves the station, we can use the equation:

v² = u² + 2as

where v is the final velocity, u is the initial velocity, a is the acceleration, and s is the distance traveled. We can split the distance traveled into two parts: the distance covered while accelerating, and the length of the station.

For the distance covered while accelerating, the initial velocity is 22.0 m/s, the acceleration is -0.150 m/s² (opposite to the motion of the train), and the distance is the length of the station minus the initial distance covered by the train:

s₁ = (210.0 m - 0 m) - (130.0 m + 22.0 m/s × t) = 80.0 m - 22.0 m/s × t

where t is the time taken to cover the distance.

For the distance covered in the station, the initial velocity is the final velocity from the acceleration phase, and the acceleration is 0 (since the train is no longer accelerating):

s₂= 130.0 m

The total distance traveled is the sum of s₁ and s₂:

s = s₁+ s₂ = 80.0 m - 22.0 m/s × t + 130.0 m

Substituting the given values into the first equation, we get:

v² = (22.0 m/s)² + 2 × (-0.150 m/s²) × [80.0 m - 22.0 m/s × t + 130.0 m]

Simplifying, we get:

v² = 22.0² - 0.3t + 2.0 × 130.0

v² = 484 - 0.3t + 260

v² = 744 - 0.3t

Taking the square root of both sides, we get:

v = √(744 - 0.3t)

At the moment when the nose of the train leaves the station, the distance traveled is 210.0 m. Therefore, we can set s = 210.0 m and solve for t:

210.0 = 80.0 m - 22.0 m/s × t + 130.0 m

Simplifying, we get:

t = 4.32 s

Substituting this value into the expression for v, we get:

v = √(744 - 0.3 × 4.32)

v = 27.4 m/s

Therefore, the final velocity of the train when the nose leaves the station is 27.4 m/s.

(b) The time that the nose of the train spends in the station is the time it takes to travel the length of the station at a constant speed, which is the time between the end of the acceleration phase and the moment when the nose leaves the station. From part (a), we know that the acceleration phase lasts for:

t₁= (v - u) / a = (27.4 m/s - 22.0 m/s) / (-0.150 m/s²) = 36.67 s

Therefore, the total time it takes for the nose to leave the station is:

t₂ = t₁ + 4.32 s = 41.0 s

The time that the nose of the train spends in the station is:

t_station = t₂- t₁ = 4.32 s

Therefore, the nose of the train is in the station for 4.32 seconds.

(c) The velocity of the end of the train as it leaves the station can be found using the same kinematic equation:

v² = u²+ 2as

where v is the final velocity, u is the initial velocity, a is the acceleration, and s is the distance.

In this case, the initial velocity is 22.0 m/s, the acceleration is -0.150 m/s², and the distance is the length of the station:

s = 210.0 m

Substituting these values, we get:

v² = (22.0 m/s)² + 2(-0.150 m/s²)(210.0 m)

v² = 484.0 m²/s² - 63.0 m²/s²

v² = 421.0 m²/s²

Taking the square root of both sides, we get:

v = 20.5 m/s

Therefore, the velocity of the end of the train as it leaves the station is 20.5 m/s.

(d) To find the time when the end of the train leaves the station, we can use the same kinematic equation used in part (b):

s = ut + (1/2)at²

where s is the displacement of the end of the train, which is 210.0 m + 130.0 m = 340.0 m, u is the initial velocity of the train, and a is the acceleration of the train.

Substituting the given values, we get:

340.0 m = (22.0 m/s)t + (1/2)(-0.150 m/s²)t²

Simplifying and solving for t, we get:

t = 15.74 s

Therefore, the end of the train leaves the station after 15.74 seconds.

The cork leaves the spring at a speed of 3.02 m/s.

We can use the conservation of energy to determine the speed at which the cork leaves the spring.

The initial potential energy stored in the spring is converted to the kinetic energy of the cork as it leaves the spring. Neglecting air resistance, the conservation of energy equation is:

(1/2) k x^2 = (1/2) m v^2

where k is the spring constant, x is the distance the spring is compressed, m is the mass of the cork, and v is the speed of the cork as it leaves the spring.

Substituting the given values:

(1/2) * 18 N/m * (7.47 cm / 100 cm/m)^2 = (1/2) * 0.009 kg * v^2

Solving for v:

v^2 = (18 N/m * (7.47 cm / 100 cm/m)^2) / 0.009 kg

v^2 = 9.119 m^2/s^2

\(m=2\;\text{kg}\)

Therefore, the mass of the skateboard is 2 kg.

The incline angle should be about 4.7 degrees and the block's acceleration would be greater than that of the rolling sphere.

a) Let M be the mass of the sphere, R be its radius, and θ be the incline angle. When the sphere rolls down the incline without slipping, the friction force acting on it causes a torque about its center of mass, which results in a rotational acceleration. If a is the linear acceleration of the center of mass, and α is the angular acceleration, then we have:

a = α R

Also, the torque τ caused by the friction force is given by:

\(τ = I α\)

where I is the moment of inertia of the sphere about its center of mass. For a solid sphere, I is given by:

\(I = (2/5) M R^2\)

Since the sphere rolls without slipping, the friction force is related to the normal force N by:

\(f = μ N\)

where f is the friction force, and μ is the coefficient of static friction. The normal force is related to the weight of the sphere by:

N = M g cos θ

where g is the acceleration due to gravity.

The net force acting on the sphere down the incline is given by:

\(Fnet = M g sin θ - f\)

The linear acceleration of the center of mass is given by:

\(a = Fnet / M\)

Substituting for f and N, we get:

\(a = g (sin θ - μ cos θ)\)

Equating this to α R, we get:

g (sin θ - μ cos θ) = α R

Substituting for α using the expression for I and τ, we get:

\(g (sin θ - μ cos θ) = τ / (2/5 M R)\)

Substituting for τ using the expression for f and N, we get:

\(g (sin θ - μ cos θ) = (μ M g cos θ) R / (2/5)\)

Simplifying, we get:

\(tan θ = (5/7) μ\)

Substituting the given values, we get:

tan θ = (5/7) (0.23)

\(θ = arctan(0.082)\)

θ = 4.7 degrees (approximately)

Therefore, the incline angle should be about 4.7 degrees

b) Since the block is frictionless, its acceleration down the incline is given by:

a' = g sin θ

Substituting the value of θ obtained in part a), we get:

a' = g sin(4.7) ≈ 0.41 g

Since this is greater than 0.23g, the block's acceleration would be greater than that of the rolling sphere.

b) the total baryon number before and after the interaction is the same:

B_before = 1 (proton) + 1 (neutron) = 2

B_after = 1 (neutron) + 1 (neutron) + 1 (Λ0) = 3

c) This interaction is controlled by the strong interaction, which is one of the four fundamental forces of nature.

What is an interaction ?

a) The interaction between a proton and an antiproton can be written at the quark level as:

uud + uud → udd + udd + uubar + uubar.

where u, d, and ubar denote the up quark, down quark, and anti-up quark, respectively. This interaction does not involve any quark flavor change since the number of each type of quark (up, down, and anti-up) is conserved.

What is baryon?

b) Baryon number (B) is defined as the total number of baryons minus the total number of antibaryons. In this interaction, we start with two baryons (a proton and a neutron) and end with three baryons (two neutrons and a Λ0 particle) and no antibaryons. Therefore, the change in baryon number is:

ΔB = (number of baryons) - (number of antibaryons) = 2 - 0 = 2

Since ΔB is non-zero, we might think that baryon number is not conserved. However, it is important to note that the Λ0 particle is a baryon with a baryon number of +1, which cancels out the baryon number of the two neutrons (-1 each). Therefore, the total baryon number before and after the interaction is the same:

B_before = 1 (proton) + 1 (neutron) = 2

B_after = 1 (neutron) + 1 (neutron) + 1 (Λ0) = 3

Therefore, baryon number is conserved in this interaction.

c) This interaction is controlled by the strong interaction, which is one of the four fundamental forces of nature. The strong interaction is responsible for binding quarks together to form hadrons, such as protons, neutrons, and Λ0 particles. The exchange of gluons, which are the carrier particles of the strong force, between quarks is what allows them to interact and bind together. The fact that this interaction involves the production of multiple hadrons and conservation of baryon number is consistent with it being a strong interaction. Additionally, experiments have shown that the strong force is responsible for binding protons and neutrons together in the nucleus of an atom.

Pascal's principle states that pressure increases by the same amount throughout an enclosed or confined fluid. Archimedes' principle states that the buoyant force acting on a submerged object is equal to the weight of the volume of fluid displaced by the object.

The wave velocity is found to be v = w/k.

The velocity associated with the disturbance propagating in the given medium is defined as wave velocity; in other words, wave velocity is the distance traveled by waves per unit of time.

The wave velocity is determined by the medium employed.

The wave velocity is often referred to as the phase velocity.

The perturbations in wave motion pass across the medium as a result of the particles' recurrent periodic oscillations. The velocity of the wave will differ from the velocity with which the particles vibrate about their mean positions. The wave velocity will always be constant, while the particle velocity will vary over time.

Given that

E = E₀ sin(kx-wt)j

B = B₀ sin(kx-wt)j

E₀ - Amplitude of electric field

B₀ - Amplitude of magnetic field

and k = 2π/λ

λ = 2π/k

and w = 2πn

where n is the angular frequency

Thus, the velocity of the wave

v= nλ

v = (w/2π) (2π/k)

v = w/k
