At $0.095/kwh, what does it cost to leave a 25 w porch light on day and night for a year?

The correct answer is granular segregation; coarse-grained.

Granular segregation is the process by which particles of different sizes and densities are sorted within a flowing mixture. In the case of debris flows, the coarsest particles, such as boulders and cobbles, tend to be concentrated at the flow front, while the finest particles, such as sand and silt, are carried along in the flow. This is because the coarser particles have more inertia and are less likely to be suspended in the flow. The process of granular segregation is important because it can have a significant impact on the destructive power of debris flows. Debris flows that are concentrated with coarse particles can cause more damage to structures and infrastructure than debris flows that are composed of finer particles. In addition to granular segregation, other factors that can affect the distribution of clasts in debris flows include the slope of the valley, the amount of water in the flow, and the viscosity of the flow.

Answer:

Capacitor

Explanation:

Capacitor ; A capacitor is a passive two-terminal electrical component that can store energy in an electric field electrostatically. It works as a small rechargeable battery that stores electricity. However, unlike a battery, it can charge and discharge in the split of a second. Capacitors are widely used to build different types of electronic circuits.

The voltage across one of the lamps will be 220V. This is because when components are connected in parallel, the voltage across each component is the same as the voltage across the source.

Voltage is a measure of the potential difference in electrical energy between two points. It is measured in volts and is the electrical force that causes current to flow in an electrical circuit. Voltage is the energy per unit charge that causes a current to flow through a conductor. It can be compared to the pressure of water in a pipe, where the greater the pressure, the more water that can be pushed through the pipe. Voltage is the primary factor in determining the amount of electrical current that can be produced in an electrical circuit. Voltage is also related to the amount of power that can be produced in an electrical circuit. Voltage can be generated by a variety of sources, such as batteries, generators, and rectifiers.

Answer: The material that is not a mixture; it has the same properties all the way through is called a substance.

Explanation:

A pure substance is a form of matter that has a constant composition and properties that are constant throughout the sample. Hence, it cannot be separated by physical means. Example: Gold

Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present. They can be separated by physical means as well. Example: Air

Thus the material that is not a mixture; it has the same properties all the way through is called a substance.

Solar winds, which are streams of charged particles emanating from the sun, are often deviated by the Earth's magnetic field. This is because the magnetic field acts as a shield, deflecting the charged particles away from our planet.

The Earth's magnetic field is created by the motion of molten iron in the core of the planet, which generates electric currents and produces the magnetic field.
However, sometimes solar winds can penetrate the Earth's magnetic field, particularly at the poles where the magnetic field is weaker. When this happens, the charged particles can interact with the Earth's atmosphere, causing phenomena such as the aurora borealis (Northern Lights).

In addition to the Earth's magnetic field, other factors can also influence the path of solar winds. For example, the speed and density of the solar wind, as well as the orientation of the magnetic field within the solar wind, can all play a role in determining whether the solar winds will be deviated by the Earth's magnetic field or not.

Answer:

When two players are running full speed at each other on a football field they build up their momentum

Answer:

The pressure value changes 400 % relative to the initial value.

Explanation:

Let suppose that the gas behaves ideally and represents a closed system, that is, a system with no mass interactions so that number of moles is conserved (\(n\)). Since the variables involved in the isothermal process are pressure (\(P\)) and volume (\(V\)). Finally, the process is represented by the following relationship:

\(P_{1}\cdot V_{1} = P_{2}\cdot V_{2}\) (1)

Where:

\(P_{1}, P_{2}\) - Initial and final pressures.

\(V_{1}, V_{2}\) - Initial and final volumes.

If we know that \(P_{1} = P_{o}\), \(V_{1} = V_{o}\) and \(V_{2} = 0.2\cdot V_{o}\), then the final pressure of the closed system is:

\(P_{2} = P_{1}\cdot \left(\frac{V_{1}}{V_{2}} \right)\)

\(P_{2} = 5\cdot P_{o}\)

The pressure value changes 400 % relative to the initial value.

The photoelectric effect

The photoelectric effect supports the particle model of light. Hence option A is correct.

When a substance absorbs electromagnetic radiation, a process known as the photoelectric effect causes electrically charged particles to be discharged from or inside the material. When light strikes a metal plate, the action is frequently described as the ejection of electrons from the plate. In a more general definition, the substance may be solid, liquid, or gas, the radiant energy may take the form of infrared, visible, or ultraviolet light, X-rays, or gamma rays, and the discharged particles may include ions (electrically charged atoms or molecules) in addition to electrons. Because of the perplexing concerns it presented about the nature of light—particle versus wavelike behavior—that were eventually answered by Albert Einstein in 1905, the phenomenon was critically important in the development of modern physics.

The vertical component of the ball's velocity is 24.9 m/s, and the horizontal component is 60.1 m/s.

To determine the vertical and horizontal components of the ball's velocity, we can use trigonometry. The initial velocity of the ball can be broken down into its vertical and horizontal components.

The vertical component of velocity can be found using the formula: V_vertical = V_initial * sin(theta), where V_initial is the initial velocity and theta is the angle of projection.

In this case, V_initial is 40 m/s and the angle is 22.5°. Plugging in these values, we get: V_vertical = 40 m/s * sin(22.5°) ≈ 24.9 m/s.The horizontal component of velocity can be found using the formula: V_horizontal = V_initial * cos(theta), where V_initial is the initial velocity and theta is the angle of projection.

Plugging in the values, we get: V_horizontal = 40 m/s * cos(22.5°) ≈ 60.1 m/s. Therefore, the vertical component of the ball's velocity is approximately 24.9 m/s, and the horizontal component is approximately 60.1 m/s. Option (a) - 24.9 m/s, 60.1 m/s - represents the correct answer.

Answer:

Av = 12.9 [km/h]

Explanation:

We must remember that the average speed is defined as the relationship between the space traveled over a certain time.

\(Av = x/t\)

where:

Av = average speed [km/h]

x = distance [km]

t = time [hr]

For when he was on the bus

The distance can be calculated by clearing the equation, for the term of the distance

\(x_{1}= A_{v}*t\\x_{1}= 15*1.6\\x_{1}=24[km]\)

For when Andy was walking

\(x_{2}=A_{v}*t\\x_{2}=4.5*0.4\\x_{2}=1.8 [km]\)

Now the total time is the sum of 1.6 + 0.4 = 2 [hr], and the total distance is the sum of the distances calculated above.

\(x = 24 + 1.8\\x = 25.8 [km]\)

The average speed is calculated using the ratio of space to time.

\(Av = 25.8/2\\Av = 12.9 [km/h]\)

than the original string. The local repeating patterns of the original string are exposed in the BWT. The BWT operates by cyclically rotating the original string and lexicographically sorting the rotations. The BWT is built from the final character of each rotation. The BWT exposes the local repeating patterns in the original string by grouping related characters together. This characteristic makes string compression simpler since same-character runs may be encoded more efficiently. As a result of lexicographically sorting the rotations, the BWT obtains longer same-character runs.

This is a projectile launching exercise, let's start by looking for the time it takes for the rock to reach the height of the window.

Let's use trigonometry to find the velocities of the rock

           sin 40 = \(v_{oy}\) / v

           cos 40 = v₀ₓ / v

           v_{oy}= v sin 40

           v₀ₓ = v cos 40

           v_{oy} = 30 sin 40 = 19.28 m / s

           v₀ₓ = v cos 40

           v₀ₓ = 30 cos 40 = 22.98 m / s

we look for the time

        \(v_{y}^2\) = v_{oy}^2 - 2 g y

         v_{y}^2 = 19.28 2 - 2 9.8 16 = 371.71 - 313.6 = 58.118

        v_{y} = 7.623 m / s

we calculate the time

          v_{y} = v_{oy} - gt

          t = (v_{oy} - v_{y}) / g

          t = (19.28 -7.623) / 9.8

          t = 1,189 s

since the time is the same for both movements let's use this time to find the horizontal distance

           x = v₀ₓ t

           x = 22.98 1,189

           x = 27.3 m
