The wavelength is equal to 15 meters, which is twice the length of the medium, this standing wave pattern has a wavelength of 7.5 meters.

In a standing wave, the wavelength is related to the length of the medium and the number of antinodes (or nodes) formed. The wavelength is equal to twice the length of the medium divided by the number of antinodes. Therefore, we can determine the standing wave with a wavelength of 7.5 meters by finding a pattern that satisfies this condition.

Let's consider the possible standing wave patterns given in the image below:

O--O--O--O--O--O--O

|  |  |  |  |  |  |

O  O  O  O  O  O  O

In this diagram, the "O" represents a node, where there is no movement in the wave, and the "|" represents an antinode, where there is maximum displacement. The distance between two adjacent nodes or antinodes is half the wavelength.

To have a wavelength of 7.5 meters, the length of the medium should be an integer multiple of half the wavelength. Looking at the standing wave patterns, we can see that the third pattern satisfies this condition. The length of the medium in this pattern is 15 meters (7.5 meters x 2), and there are two antinodes. Therefore, the wavelength of the standing wave is:

wavelength = 2 x length of medium / number of antinodes

= 2 x 15 meters / 2

= 15 meters / 1

Explanation: When a liquid changes into a gas vaporization has occurred. The process can either occur due to boiling or evaporation. Boiling occurs when the vapor pressure of the liquid is raised (by heating) to the point where it is equal to the atmospheric pressure.

You can use thermal energy to change a liquid into a gas.

By virtue of its temperature, a system in a condition of thermodynamic equilibrium has thermal energy, or internal energy. Unlike the energy of systems that are not in a state of thermodynamic equilibrium, thermal energy cannot be transformed into meaningful work as quickly.

For instance, the same fluid or solid in a thermodynamic equilibrium state with the same energy (as thermal energy) cannot do work unless it is combined with another substance at a different temperature, as in a heat engine.

The total energy needed is 2,418 Joules.

To calculate the total energy needed, we need to consider two steps: heating the water to 100°C and vaporizing it to steam.

Step 1: Heating the water

We use the equation Q = mcΔT, where Q is the energy needed, m is the mass, c is the specific heat of water (4.18 J/g°C), and ΔT is the temperature change.

Q1 = (10 g)(4.18 J/g°C)(100°C - 20°C) = 3,340 J

Step 2: Vaporizing the water
We use the equation Q = mL, where L is the heat of vaporization (2,260 J/g).
Q2 = (10 g)(2,260 J/g) = 22,600 J

Total energy needed: Q = Q1 + Q2 = 3,340 J + 22,600 J = 25,940 J.

m1 • v1 + m2 • v2 = m1 • v1' + m2 • v2'

m1 and m2 are the masses so

63v1 + 55v2 = 63v1' + 55v2'

v1 and v2 represent the velocities before the collision, so

(63)(0) + (55)(0) = 63v1' + 55v2'

v1' and v2' represent the velocities after the collision, so

(63)(0) + (55)(0) = (63)(3.3) + (55)v2' <-- We're looking for v2'

0 + 0 = 207.9 + 55v2'

-207.9 = 55v2'

-3.78 m/s = v2'

Net force is the sum of all the forces.

Explanation:

Force is the push or pull that causes acceleration.

Net force is the sum of all the forces acting on an object

The outcome is a force when an external force pushes or pulls on one thing as it interacts with another object. On the other hand, there won't be any evidence of force if both objects are imprisoned in one location and there isn't any outside pressure.

For example,

When Mathew pushes an automobile, they provide force to the vehicle while dissipating energy; this is shown by the fact that Mathew pushes the car with an 8 Newton (8 N) force.

The amount of force acting on an item from both sides is known as a net force whenever several forces are present, regardless of the direction they are acting from.

The resultant force is another term for this force.

For example,

James pulls a rope from one side, while Thomas pulls a rope from the other, such that a force is exerted on the rope from both sides. This pulling force from both sides is referred to as Net force.

Hydrogenation is the process of adding hydrogen atoms to a compound. The success of hydrogenation can be determined by analyzing the frequency (wavenumber) of the compound before and after the process. The wavenumber is the number of waves per unit length and is related to the energy of the molecule.

Before hydrogenation, the compound will have a certain wavenumber, which is related to the energy of the molecule. After hydrogenation, the wavenumber will change, indicating a change in the energy of the molecule. If the wavenumber decreases, it indicates that the hydrogenation was successful, as the molecule now has less energy and is more stable.

The wavenumber can be determined using infrared (IR) spectroscopy, which measures the absorption of infrared radiation by the compound. The absorption peaks in the IR spectrum correspond to the wavenumbers of the compound. By comparing the wavenumbers before and after hydrogenation, the success of the process can be determined.

In conclusion, the frequency (wavenumber) of a compound can reflect the success of hydrogenation by indicating a change in the energy of the molecule. A decrease in wavenumber after hydrogenation indicates that the process was successful.

Explanation:

The amount of space between rock and soil that can hold water is known as porosity. Porosity is a measure of the void spaces in a material, typically expressed as a percentage of the total volume of the material. In other words, it's the ratio of the volume of pore space in a rock or soil to the total volume of the rock or soil.

The porosity of rock and soil can vary widely, depending on the type of rock or soil and the conditions under which it formed. For example, some types of rock, such as sandstone, have high porosity (around 30-40%) because they are composed mostly of grains of sand that are held together by a small amount of cement. Other types of rock, such as granite, have very low porosity (around 1-2%) because they are composed mostly of tightly packed mineral crystals.

Soil, on the other hand, can have a wide range of porosity depending on the soil type. Sandy soils tend to have higher porosity than clay soils, but even within a soil type, porosity can vary greatly depending on the soil structure, organic matter content, and other factors.

In general, the porosity of rock and soil can range from less than 1% to over 40%. In order to hold water, the porosity should be greater than zero.

To find the net force with two forces, you need to add the two forces together if they are in the same direction, or subtract them if they are in opposite directions.

So, the net force with two forces is found by adding the forces together if they are in the same direction, or subtracting them if they are in opposite directions.

Explanation:

The "expert verified answer" is blatantly incorrect and incomplete, I have no idea how Brainly keeps getting away with this.

I am assuming this is a reversible adiabatic system, s₂=s₁.

Looking up s₁ in thermodynamic table B.1.2 at 6Mpa & 600°C:

s₂=s₁=7.1676

We'll use the NKEPE turbine equation:

Wout = h₁-h₂

For this equation we'll need h₁ from the same table:

h₁=3658.4

Using the same table at 600kPa, interpolate T₂ using the value of s we previously determined:

T₂= 246.7 °C

Using the same table at 600kPa, interpolate h₂ using either T₂ or s₂:

h₂≈2950.1931

Back to the aforementioned equation:

Wout = h₁-h₂

Wout ≈ 3658.4-2950.1931

Explanation:

The velocity of the caboose is constant, so the acceleration is zero. Therefore, the caboose's acceleration is 0 m/s².

Acceleration is the rate at which the velocity of an object changes over time. The formula for acceleration is expressed as a = (v - u) / t where a is acceleration, v is final velocity, u is initial velocity, and t is time.

The velocity of the train and the caboose is the same. The caboose breaks loose and starts rolling freely along the track. Therefore, the velocity of the caboose is the same as the velocity of the train.

Given that the train moves at a constant velocity, the initial velocity of the caboose is the same as the final velocity.

Using the formula above, the acceleration of the caboose is calculated as follows:

a = (v - u) / ta

= (0 - 0) / 5.0

a = 0 m/s²

Therefore, the acceleration of the caboose is 0 m/s². This result makes sense since the caboose is moving at constant velocity.

Explanation:

When the ball is placed in this pool of water, part of the ball would be beneath the surface of the pool. The volume of the water that this ball displaced is equal to the volume of the ball that is beneath the water surface.

The buoyancy force on this ball would be equal in magnitude to the weight of water that this ball has displaced.

Let \(m(\text{ball})\) denote the mass of this ball. Let \(m(\text{water})\) denote the mass of water that this ball has displaced.

Let \(g\) denote the gravitational field strength. The weight of this ball would be \(m(\text{ball}) \, g\). Likewise, the weight of water displaced would be \(m(\text{water})\, g\).

For this ball to stay afloat, the buoyancy force on this ball should be greater than or equal to the weight of this ball. In other words:

\(\text{buoyancy} \ge m(\text{ball})\, g\).

At the same time, buoyancy is equal in magnitude the the weight of water displaced. Thus:

\(\text{buoyancy} = m(\text{water}) \, g\).

Therefore:

\(m(\text{water})\, g = \text{buoyancy} \ge m(\text{ball})\, g\).

\(m(\text{water}) \ge m(\text{ball})\).

In other words, the mass of water that this ball displaced should be greater than or equal to the mass of of the ball. Let \(\rho(\text{water})\) denote the density of water. The volume of water that this ball should displace would be:

\(\begin{aligned}V(\text{water}) &= \frac{m(\text{water})}{\rho(\text{water})} \\ &\ge \frac{m(\text{ball}))}{\rho(\text{water})} \end{aligned}\).

Given that \(m(\text{ball}) = 2000\; {\rm g}\) while \(\rho = 1.00\; {\rm g\cdot cm^{-3}}\):

\(\begin{aligned}V(\text{water}) &\ge \frac{m(\text{ball}))}{\rho(\text{water})} \\ &= \frac{2000\; {\rm g}}{1.00\; {\rm g\cdot cm^{-3}}} \\ &= 2000\; {\rm cm^{3}}\end{aligned}\).

In other words, for this ball to stay afloat, at least \(2000\; {\rm cm^{3}}\) of the volume of this ball should be under water. Therefore, the volume of this ball should be at least \(2000\; {\rm cm^{3}}\!\).
