Explanation:

v(t) = t³-3t²+12t+4 on the interval 0≤t≤3

has a derivative v'(t) = 3t²-6t+12 ... which is the acceleration of the particle.

To find the maximum acceleration, we want to plug t=3 into our acceleration equation.

v'(3) = a(3) = 3(3)²-6(3)+12 = 21

The magnitude of the electric field on the axis of the disk at a distance of 11.3 cm from the disk's center is \(6.62 x 10^4 N/C.\)

Yes, an electric field can affect a magnetic field. Electric and magnetic fields are closely related and can interact with each other to produce electromagnetic phenomena.

According to Maxwell's equations, a changing electric field creates a magnetic field, and a changing magnetic field creates an electric field. This means that the presence of an electric field can cause a change in a magnetic field, and vice versa.

The given numerical can be solved:

E = k * Q / (2 * R * h)

Replacing the given values, we get:

E = \((8.99 x 10^9 N \times m^2 / C^2) \times (196 x 10^-9 C) / (2 \times 0.103 m \times 0.113 m) = 6.62 x 10^4 N/C\)

So the magnitude of the electric field on the axis of the disk at a distance of 11.3 cm from the disk's center is\(6.62 x 10^4 N/C.\)

Answer:

False. Not everything can turn into a black hole. The formation of a black hole requires a massive object, typically a star, to collapse under its own gravity. This collapse causes the object to become so dense that it creates a singularity, a point of infinite density at the center of the black hole, which is surrounded by an event horizon, the point of no return beyond which nothing, not even light, can escape. So, only objects with sufficient mass and gravity can become black holes.

By applying Gauss's Law and using the appropriate Gaussian surface for each point, you can find the strength and direction of the electric field at points 4 cm, 8 cm, and 12 cm from the center of the hollow metal sphere.

Gauss's Law states that the electric field through a closed surface is proportional to the total charge enclosed by the surface.

In this case, we have a hollow metal sphere with different surface charge densities on the inside and outside surfaces. To find the electric field at the specified points, we need to consider the contributions from both the inner and outer surface charges.

To calculate the electric field at a point outside the sphere, such as 4 cm, 8 cm, or 12 cm from the center, we can consider a Gaussian surface in the form of a sphere centered at the center of the hollow metal sphere. The radius of this Gaussian surface should be larger than the outer radius of the metal sphere.

Since the charge on the inner surface of the hollow sphere is negative (-100 nC/m^2), it will create an electric field directed towards the inside of the sphere. On the other hand, the charge on the outer surface of the sphere is positive (100 nC/m^2), creating an electric field directed away from the sphere.

To determine the electric field at a point outside the sphere, we only need to consider the contribution from the outer surface charge, as the inner surface charge is shielded by the metal.

Let's calculate the electric field at the specified points using Gauss's Law:

1. At 4 cm from the center:
  The electric field due to the outer surface charge will be radially outward.
  To calculate the electric field at this point, we can consider a Gaussian surface of radius 4 cm centered at the center of the hollow sphere.
  The electric field at this point can be calculated using the formula:
  Electric field = (Surface charge density * Gaussian surface area) / (ε0),
  where ε0 is the vacuum permittivity.

2. At 8 cm from the center:
  The electric field due to the outer surface charge will also be radially outward.
  To calculate the electric field at this point, we can consider a Gaussian surface of radius 8 cm centered at the center of the hollow sphere.
  The electric field at this point can be calculated using the same formula mentioned above.

3. At 12 cm from the center:
  The electric field due to the outer surface charge will still be radially outward.
  To calculate the electric field at this point, we can consider a Gaussian surface of radius 12 cm centered at the center of the hollow sphere.
  Again, we can use the same formula to calculate the electric field.

By applying Gauss's Law and using the appropriate Gaussian surface for each point, you can find the strength and direction of the electric field at points 4 cm, 8 cm, and 12 cm from the center of the hollow metal sphere.

Answer:

Inertia

Explanation:

The term for the tendency is inertia.

The inertia of a body is the tendency of the body to remain unmoved when at rest and the tendency to keep moving when in motion. In other words, it is the tendency of a body to remain in a state of rest or motion.

A static body will remain in a state of perpetual rest if no force acts on it and a moving body will keep moving in the same direction if no force acts on it. The force that needs to be overcome in order to change the state of the object is otherwise known as inertia force.

The given wave function of an electron is as follows:y(x) = c = 0 {x < 1} 1 ≤ x ≤ 16 {1 ≤ x ≤ 16} {x > 16}Where c is a positive real number.(a) The probability of finding the electron in the range 2 ≤ x ≤ 11 is calculated as follows.

Here, we use the formula for finding probability: P = ∫|y(x)|²dx for 2 ≤ x ≤ 11= ∫|c|²dx for 2 ≤ x ≤ 11= ∫c²dx for 2 ≤ x ≤ 11= c² (x) |₂ ᵢ=₁₁= c² (11) - c² (2) Hence, the required probability is c² (11) - c² (2). (b) The electron is most likely to be found at x = 8.5. ExplanationThe probability of finding the electron in the range 2 ≤ x ≤ 11 is calculated using the formula for probability, P = ∫|y(x)|²dx for 2 ≤ x ≤ 11.

Hence, the probability of finding the electron in the range 2 ≤ x ≤ 11 is c² (11) - c² (2). The electron is most likely to be found in the range where the wave function is the highest. The wave function has a maximum value at x = 8.5, so the electron is most likely to be found at x = 8.5.

The direction of the magnetic field of a current-carrying wire can be determined using the right-hand rule.

This rule states that if you wrap your right-hand fingers around the wire in the direction of the current flow, with your thumb pointing in the direction of the wire, your curled fingers will point in the direction of the magnetic field.

So, to detail ans this question, we need to know the direction of the current flow in the wire in order to determine the direction of the magnetic field.

To determine the direction of the magnetic field of a current-carrying wire, you can follow these steps using the Right-Hand Rule:

Straighten your right hand with your thumb pointing up.
Wrap your fingers around the wire with your thumb pointing in the direction of the conventional current (from positive to negative).
The direction in which your fingers curl around the wire represents the direction of the magnetic field.

So, to determine the direction of the magnetic field of the current-carrying wire, simply apply the Right-Hand Rule.

Explanation:

The acceleration of an object in free fall motion is the constant acceleration due to gravity

(i) The gradient of the rocket at point B is approximately -9.81 m/s²

(ii) The reason why the gradient is -9.81 m/s² is as follows;

The given graph is the speed to time graph with the upward direction taken as positive

Given that at point B the object is at the maximum point, the upward motion due to the rocket stops, the motion of the rocket is then due to gravity

Therefore, the gradient at B, is given as follows;

\(Gradient = \dfrac{\Delta v}{\Delta t } = \dfrac{d(u + a \cdot t)}{dt} =a\)

At point B the only force acting on the rocket is the force of gravity, therefore, the acceleration of the rocket at B, a = g, acceleration due to gravity ≈  9.81 m/s², and the rocket is falling due to its weight

Therefore, only gravitational force is acting on the rocket when the direction of the rocket changes and rocket falls freely, at B, and the acceleration of the rocket at B = g = 9.81 m/s²

The highest-frequency square wave that can transmit under the assumption that you could transmit digital data over FM is limited by the maximum frequency deviation of the FM signal.

Frequency modulation (FM) is a technique of conveying digital data through radio signals. FM radio works by altering the frequency of the carrier wave to represent the information being transmitted. The bandwidth of an FM signal is determined by its maximum frequency deviation, which is the amount by which the instantaneous frequency of the modulated carrier signal differs from the center frequency. This deviation is determined by the modulation index (m) and the maximum modulating frequency (fm) as shown below:

Maximum frequency deviation = m x fm

Thus, the highest-frequency square wave that can be transmitted over FM is limited by the maximum frequency deviation (and hence the bandwidth) of the FM signal.
