Explanation:

they will choose the path that has not resistance

Due to the unbalanced nature of this force, surface currents, or the movement of charges, will result. Therefore, the electric field must emerge perpendicular to surfaces to prevent this.

The equilibrium would be broken if there were an electric field component parallel to the conductor's surface, which would force the electric charge to travel along the surface.

There is never an electric force component that is directed parallel to the surface of an item, whether it has a symmetrical shape or not. The electric field and force acting on an object are both always perpendicular to its surface.

The requirement that the electric field be perpendicular to any conductor's surface is one of the laws governing static electric fields and conductors.

Based on scientific data, the stone is accelerated at approximately 10 \(m/s^2\).

Given the following data:

Gravity can be defined as a force of attraction that controls the movement of the planets such as Earth around the Sun.

This ultimately implies that, gravity is a universal force of attraction that acts between all objects or matter that are having both mass and energy, and can occupy space.

Furthermore, the gravity near the Earth's surface generally makes it possible for all physical objects such as stones to possess weight and experience a free fall.

According to astronomical records, the acceleration due to gravity for an object experiencing a free fall near the Earth's surface is 9.8 \(m/s^2\).

The boundary conditions have a positive effect on the finite difference formulation of interior nodes of the medium. Boundary conditions provide constraints or information at the edges of a computational domain to determine the behavior of the system. In the finite difference method, the values at the boundary nodes are usually known or specified. By incorporating these boundary conditions into the formulation, the behavior of the system is better represented.

When the boundary conditions are properly applied, they help ensure that the finite difference scheme accurately captures the desired physics within the interior nodes. This positive effect allows for more accurate and reliable simulations, as the behavior at the boundaries influences the behavior of the entire system.

If I had to guess I would say this is what the question fully looks like:

A block having mass m travels along a horizontal frictionless surface with speed vx. What impulse must be delivered to the mass to reverse its direction and continue to travel with a speed of vx?

A) -mvx

B) -2mvx

C) 0

D) 2mvx  

E) mvx

F) none of the above

G) cannot be determined

Explanation: The answer is

The initial momentum is m vx. So what change do you need to have a momentum -m vx afterwards? -2 m vx, because m vx + (-2m vx) = - m vx

So the correct answer is b.

The impulse must be delivered to the mass to reverse its direction and continue to travel with a speed of vx having a mass of m is  -2mvx.

Momentum is metric for power and how challenging it is to stop an object. Zero momentum applies to any object that is not moving. Tremendous, slow-moving objects have large amounts of impulse.

A small, swiftly moving object also possesses significant momentum. A bowling ball, for instance, has more momentum than a ping-pong ball if its velocities are equal. This is because bowling balls are larger in mass than ping-pong balls.

Given:

The mass of the block, m = m kg,

The speed of block, v = vx m / s,

The changed speed, V = -vx m / s

Calculate the impulse by using momentum conservation as shown below,

Initial momentum  = changed momentum

-mvx = X + mvx

X = -2mvx

Therefore, the impulse must be delivered to the mass to reverse its direction and continue to travel with a speed of vx having a mass of m is  -2mvx.

Part 1: The number of pathways in a circuit determines the possible routes for electric current to flow.

There are maximum of five pathways in this circuit, depending on its complexity and the arrangement of components.

Part 2: Determining whether the circuit is series or parallel requires more information.

In a series circuit, components are connected in a single path, and the current flows through each component sequentially.

If the circuit has only one pathway (zero or one pathway), it suggests a series circuit.

However, if the circuit has multiple pathways (two or more pathways), it indicates a parallel circuit.

Group of answer choices.

A. Cue overload principle.

B. Recall effect.

C. Encoding specificity principle.

Answer:

C. Encoding specificity principle

Explanation:

Memory can be defined as the ability of an individual to assimilate information, store this information and recall or retrieve it later in the future.

Generally, there are basically three (3) processes associated with memory and these include;

1. Encoding of data: it involves the process of getting data (informations) into our memory.

2. Storage of data: it simply involves the process of storing and maintaining data (informations) in our memory.

3. Retrieval of data: it involves the process of getting or retrieving data (informations) out of our memory.

According to cognitive psychologists, the process of retrieving or getting data out of our memory can fail or be successful depending on a number of factors such as situation, condition, or context.

An encoding specificity principle states that an individual's memory is enhanced and improved when data (informations) made available during the process of encoding is also available at retrieval (decoding).

For instance, if students were tested in the same classroom where they were taught, there is a better chance of retrieving or recalling informations than testing them in a different classroom all together.

Hence, an encoding specificity principle suggest that when the conditions present during the encoding of information into memory are made available during retrieval, this would improve and enhance the recall of such informations.

The correctly represents the gravitational potential energy of a system is = - ΣGM₁M₂/R. Negative sign appears as gravitational force is attractive force.

Potential energy is a form of stored energy that is dependent on the relationship between different system components. When a spring is compressed or stretched, its potential energy increases.

If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy. It is capable of performing more work when raised.

Potential energy is a characteristic of systems rather than of particular bodies or particles; for instance, the system made up of Earth and the elevated ball has more potential energy as they become further apart.

Answer:

Approximately \(1.5\; {\rm s}\).

(Assumptions: \(g = 9.81\; {\rm m\cdot s^{-2}}\); air resistance on the volleyball is negligible.)

Explanation:

Under the assumptions, acceleration of the volleyball would be \(a = (-g) = (-9.81)\; {\rm m\cdot s^{-2}}\) during the entire flight. (This value is negative since the ball is accelerating downwards- toward the ground.)

By the time the volleyball hits the ground, the volleyball would be at a position \(2.0\; {\rm m}\) below where it was launched. In other words, the (vertical) displacement of the volleyball during the entire flight would be \(x = (-2.0)\; {\rm m}\). (Negative since the ball is below where it was launched.)

Apply the SUVAT equation \((v^{2} - u^{2}) = 2\, a\, x\) to find the velocity of the volleyball right before hitting the ground. In this equation:

Rearrange this equation and solve for the velocity right before landing, \(v\). Note that because \(v\!\) is raised to the power of \(2\) in \((v^{2} - u^{2}) = 2\, a\, x\), both \(v = \sqrt{u^{2} + 2\, a\, x}\) and \(v = -\sqrt{u^{2} + 2\, a\, x}\) could satisfy this equation. However, \(v\!\!\) needs to be negative since the volleyball would be travelling downwards before reaching the ground.

Therefore, right before reaching the ground, velocity of the volleyball would be:

\(\begin{aligned} v &= -\sqrt{u^{2} + 2\, a\, x \\ &= -\sqrt{(6.0)^{2} + 2\, (-9.81)\, (-2.0)} \; {\rm m\cdot s^{-1}} \\ &\approx (-8.67)\; {\rm m\cdot s^{-1}}\end{aligned}\).

In other words, velocity of this volleyball has changed from \(u = 6.0\; {\rm m\cdot s^{-1}}\) (upwards) to \(v \approx (-8.67)\; {\rm m\cdot s^{-1}}\) (downwards) during this flight. Divide the change in the velocity \((v - u)\) by the rate of change in velocity \(a = (-9.81)\; {\rm m \cdot s^{-2}}\) to find the duration of this flight:

\(\begin{aligned}t &= \frac{v - u}{a} \\ &\approx \frac{(-8.67) - 6.0}{(-9.81)}\; {\rm s} \\ &\approx 1.5\; {\rm s}\end{aligned}\).

Answer:summer

Explanation:

Answer:

first day of summer

Explanation:

Answer:

We have the position vector given in terms of time t. r(t) = t^3*i + t^2*j

To find the velocity vector we have to differentiate r(t) with respect to time.

r'(t) = 3t^2*i + 2t*j

The vector representing acceleration is the derivative of the position vector

r''(t) = 6t*i + 2*j

When time t = 2.

The velocity vector is 3*2^2*i + 2*2*j

=> 12*i + 4*j

The speed is the absolute value of the velocity vector or sqrt(12^2 + 4^2) = sqrt (144 + 16) = sqrt 160

The acceleration vector is 6*2*i + 2*j

=> 12*i + 2*j

The required acceleration at t=2 is 12*i + 2*j and the speed is sqrt 160.

Answer:

an equation is balanced when the same number of each element is represented on the reactant and product sides. equations must be balanced to accurately reflect the law of conservation of matter.

To calculate the resultant force acting on the car, we must first find the acceleration at which the car is moving.

We can do this using the acceleration formula,\(a = (v_f - v_i) / t\), where \(v_f\) is the final velocity, \(v_i\) is the initial velocity, and t is time. \(a = (100 km/h - 60 km/h) / 20 s = 2 m/s*2\). Then we can use Newton's second law, \(F = m * a\), where F is the resultant force, m is the mass of the car, and a is the acceleration calculated above. \(F = 2200 kg * 2 m/s*2 = 4400 N\). To calculate the space traveled in that time, we can use the distance formula,\(d = v_i * t + 0.5 * a * t*2. d = 60 km/h * (20 s) + 0.5 * 2 m/s8*2 * (20 s)*2 = 500 m\). In short, the resultant force acting on the car is 4400 N and the distance covered in 20 seconds is 500 meters.

The inductance required for an oscillator to generate 490 nm electromagnetic waves is 2.66 * 10⁻⁹ H.

An electromagnetic wave is an oscillating wave of electric and magnetic energy, travelling through space at the speed of light. It is a form of energy that is created when electric and magnetic fields vibrate in unison. Electromagnetic waves are made up of oscillating electric and magnetic fields that travel through the air and other materials.

The inductance required for an oscillator to generate 490 nm electromagnetic waves depends on the type of oscillator being used. The equation for calculating the required inductance is L = 1 / (2 * π * f * C), where L is inductance, f is frequency,
and C is capacitance.
In this case, the frequency would be f = c / λ,
where c is the speed of light and λ is the wavelength (490 nm).
Plugging in the values, we get L = 1 / (2 * π * (3 * 10⁸ / 490 * 10⁻⁹) * 19 * 10⁻¹²) = 2.66 * 10⁻⁹ H.
So, the inductance required for an oscillator to generate 490 nm electromagnetic waves is 2.66 * 10⁻⁹ H.
