The quantity of charge on a plastic tube that has been rubbed with animal fur and gained 3. 8 x 10^9 electrons is The quantity of charge on the plastic tube is 3.8 x 10^9 electrons.

The quantity of charge on the plastic tube is 3.8 x 10^9 electrons. To calculate this value, we can use the equation q = n*e, where q is the charge, n is the number of electrons and e is the elementary charge (1.6 x 10^-19 C). Substituting in the values given, we get q = 3.8 x 10^9 * 1.6 x 10^-19 = 6.08 x 10^-10 C.  This means that the plastic tube has gained a charge of 6.08 x 10^-10 Coulombs, which is equivalent to 3.8 x 10^9 electrons.

This can be explained by the process of triboelectricity, which is the transfer of electrons between two materials due to rubbing them together. In this case, the animal fur must have had a higher electron affinity than the plastic, which caused electrons to be transferred from the fur to the plastic tube.

The slope (gradient) of the graph equals the force constant. The proportionality constant, or k, is also known as the force constant in physics. A spring that is more rigid will have a higher value for k. The graph is no longer a straight line beyond point A since the gradient has changed and the formula F = Kx is no longer valid.

The correct option is B, The electron's speed at f is equal to its speed at i.

Electrons are subatomic particles that are found in atoms. They are the negatively charged particles that orbit the nucleus of the atom, and they have an extremely small mass. Electrons travel at different speeds depending on their energy level. At their lowest energy level, electrons move at an extremely slow speed, about one thousandth of the speed of light. As the electrons gain energy, their speed increases.

In a vacuum, when electrons have the highest energy level, they can travel at a speed of nearly the speed of light, which is around 186,000 miles per second. In a vacuum, the electrons would have the same speed regardless of their mass. Electrons also move slower inside a material, such as a metal, due to the presence of other atoms. Electrons in metals usually move at a speed of about 1/10th the speed of light. This slower speed is due to the electrons having to pass through energy barriers created by the other atoms in the metal.

At his current velocity the sprinter will complete the 100.0-m dash in 28.53 s.

What is velocity?

Velocity is a vector quantity that describes the rate of change of an object's position. It is a measure of how fast an object is moving and in what direction. Velocity is measured in units of meters per second (m/s) or miles per hour (mph) and is often represented by the symbol "v".

We can use the equations of motion to calculate the time for the sprinter to complete the race.

First, we can use the equation:

v = u + at

to find the final velocity of the sprinter after accelerating for 20.0 m. Here, u is the initial velocity (which is 0 m/s since the sprinter is at rest at the start of the race), a is the acceleration of 3.20 m/s^2, and t is the time it takes for the sprinter to accelerate for 20.0 m.

v = 0 + (3.20 m/s^2)(t)

We know that the sprinter accelerates for 20.0 m, so we can use the equation:

s = ut + 1/2at^2

to find the time t:

20.0 m = (0 m/s)(t) + 1/2(3.20 m/s^2)(t^2)

t^2 = (20.0 m) * 2 / (3.20 m/s^2) = 12.5

t = sqrt(12.5) = 3.53 s

So the time it takes for the sprinter to accelerate for 20.0 m is 3.53 s.

Next, we can use the equation:

v = d/t

to find the time it takes for the sprinter to cover the remaining 80.0 m of the race at his final velocity. Here, d is the remaining distance of 80.0 m and v is the final velocity found before.

t = d/v = 80.0 m / (3.20 m/s) = 25.0 s

So the time it takes for the sprinter to cover the remaining 80.0 m of the race at his final velocity is 25.0 s

So the total time for the race is the sum of the time it takes to accelerate and the time it takes to cover the remaining distance at a constant velocity:

t = 3.53 s + 25.0 s = 28.53 s

Hence, at his current velocity the sprinter will complete the 100.0-m dash in 28.53 s.

The sum of kinetic energy and potential energy of the particles in a material is known as mechanical energy.

The energy that an object has as a result of motion is known as kinetic energy. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its acceleration until its speed changes.

Due to its position, an object has the ability to store energy. For instance, when a demolition machine's heavy ball is held in an elevated position, it is storing energy. Potential energy is the name for this positional energy that has been stored. Similar to how a drawn bow can store energy due to its posture, There is no energy in the bow while it is in its normal position, or when not drawn.

The net energy ratio of hydrogen is 0.67.

The net energy ratio, also known as energy return on investment (EROI), is a measure of the efficiency of a fuel source or energy system. It represents the ratio of the energy output to the energy input, or the amount of energy that is produced compared to the amount of energy that is required to produce it.

A net energy ratio of 1 means that the energy output is equal to the energy input, and that no net energy is produced.

In the case of hydrogen, it gives off 10 units of energy but takes 15 units of energy to produce, so the net energy ratio would be:

Energy output / Energy input = 10 units / 15 units = 0.67

With the Sun and Moon in this position, the side of the earth facing the moon experiences a spring high tide. Thus Option C is the answer.

A spring tide is a tide that occurs when the gravitational pull of the Moon and the Sun are in alignment. During a new moon or full moon phase, the gravitational pull of the Moon and the Sun combine to produce stronger than normal high tides and stronger than normal low tides. The term "spring tide" does not refer to the season of spring, but rather the tide's "springing forth" of water.

During a spring tide, the difference between high tide and low tide is at its greatest, and the water level rises higher and falls lower than during a neap tide. This is because the gravitational pull of the Moon and Sun are working together to produce the tide, rather than against each other. This results in a high tide that is higher than a normal high tide, referred to as a spring high tide.

Part B: The total angular momentum of the four-particle system is 0.95 kg.m²/s.

The expression used to calculate angular momentum L is:

                             L = r x mv

Here, r is the position vector of the object m is the mass and v is the velocity vector.

According to the superposition principle, the resultant angular momentum due to many particles is the vector sum of the individual angular momentum.

L = L₁ + L₂ + L₃ + ...

Here, L₁ is the angular momentum of a particle, L₂ is the angular momentum of the particle, and so on.

In the question

Mass of a particle = 5.0 kg

vector r = (2.0i - 3.0j) m

vector v = (3.0i) m/s

For particle 1

The position vector is 2.0j m

Substitute 0.10 kg from m₁, 2.0j from r, and 2.0i m/s for v₁ in the expression of angular momentum

L = r x mv

L₁ = (2.0jm) x [(0.10 kg)( 2.0i m/s)]

L₁ = -4.0 kg.m²/s

The angular momentum for the first particle is -4.0 kg.m²/s.

For particle 2

Position vector is (2.0i - 2.0j) m

Substitute 0.20 kg from m₂, (2.0i - 2.0j) m from r, and (3.0i - 3.0j)m/s for v₂ in the expression of angular momentum

L₂ = (2.0i - 2.0j) m x [ (0.20 kg) (3.0i - 3.0j) m/s]

L₂ = 0

The angular momentum for the second particle is 0

For particle 3

The position vector is (-3.0i + 1.0j) m.

Substitute 0.30 kg from m₃,  (-3.0i + 1.0j) m from r, and  -5.0j m/s for v₃ in the expression of angular momentum

L₃ = (-3.0i + 1.0j) m x [((-3.0i + 1.0j) m) ( -5.0j m/s)]

L₃ = 1.35 kg.m²/s

The angular momentum for three particles is 1.35 kg.m²/s.

For particle 4

The position vector is 4.01i m.

Substitute 0.40 kg from m₄, 4.0i m from r, and -4.0i m/s for v₄ in the expression of angular momentum

L₄ = (4.0i m) x [(0.40 kg) (-4.0i m/s)

L₄ = 0

The angular momentum for four particles is 0.

Part B

Formula used: L = L₁ + L₂ + L₃ + L₄

The total angular momentum of the four-particle system is calculated as follows:

By superposition principle

L = L₁ + L₂ + L₃ + L₄

L = -4.0 kg.m²/s + 0 + 1.35 kg.m²/s + 0

L = 0.95 kg.m²/s

Hence, the total angular momentum of the four-particle system is 0.95 kg.m²/s.
