nitroglycerine energy density compared to natural gas

Any substance that possesses mass and volume is considered to be matter. In general, atoms and anything composed of them are considered to be "matter."

Energy is the power to effect change or carry out work.

The connection between energy and matter is determined by the speed of light, per the theory of relativity. E = M x C^2, where E is energy, M is mass, and C is the speed of light, describes how matter and energy are related.

Matter and Energy - How are they inter-related?

The variation in a body's mass is inversely proportional to the square of the speed of light and directly correlated with the amount of energy released during the conversion process. An energy conversion process can be carried out by a system using this kind of transformations, in which some of the body's intrinsic energy is converted into thermal energy or radiant light. Also implied by this process is a loss of mass. At the atomic level, the shift of mass is significant because it demonstrates that matter is not an immutable property of the body and that it may, in fact, "disappear," releasing energy to the outside.

Answer:

Explanation:

The answer is radiation.

The wavelength of each of the two original waves is 1.2m.

In a standing wave, the distance between two adjacent nodes or antinodes is equal to half the wavelength (λ/2).

Thus, the distance between the second and fifth nodes is equal to 3λ/2.

We know that the frequency of each wave is 120 Hz. The velocity (v) of the waves can be determined using the formula v = fλ, where f is the frequency and λ is the wavelength.

For the two waves interfering to produce the standing wave, we can set up the equation:

2v = 120λ₁ = 120λ₂

where λ₁ and λ₂ are the wavelengths of the two original waves.

We also know that:

3λ/2 = λ₁/2 + λ₂/2

Substituting the first equation into the second equation, we get:

3λ/2 = 60v/120

λ = 2v/3

Substituting this value of λ into the first equation, we get:

v = 720/5 m/s

Thus, the wavelength of each of the two original waves is:

λ₁ = λ₂ = v/f = (720/5)/120 = 1.2 m

Each of the two original waves has a wavelength of 40 cm.

To determine the wavelength of each of the two original waves, we need to first find the distance between two adjacent nodes.

In a standing wave, the distance between two consecutive nodes is equal to half the wavelength (λ/2) of the original waves. Since there are three node intervals between the second and fifth nodes, we can use the given distance to determine the wavelength.

The distance between the second and fifth nodes is 3/2 of a wavelength (since there are 2 nodes per wavelength). Therefore:

3/2 λ = 60 cm

When an infrared heater is switched on, a person a few meters away begins to warm up, has moved from the heater to the person is transfer of thermal energy, this occurs through the movement of infrared radiation, which is a form of electromagnetic radiation with longer wavelengths than visible light.

Infrared heaters generate heat by emitting infrared radiation from their heating elements, such as quartz tubes or ceramic plates. This radiation travels through the air and is absorbed by objects and people in its path, including the person who feels the warmth. The absorbed radiation raises the temperature of the object or person, causing them to feel warmer.

Infrared radiation does not rely on direct contact or the movement of air, making it an efficient way of transferring heat over a distance. This type of heating is known as radiant heating, and it is different from convection heating, which relies on the movement of air particles to transfer heat. In summary, when an infrared heater is switched on, thermal energy moves from the heater to a person a few meters away via infrared radiation.

The correct answer is D. Amount of time and area of physical contact between the substances.

Explanation:

Heat transfer refers to the flow of thermal energy or heat between two or more objects. This process involves multiple factors and implies heat from the hottest object goes to the coldest one until there is an equilibrium. To begin, heat transfer depends on the amount of thermal energy in the objects because objects must have a different amount of thermal energy for heat to flow.

Besides this, the amount of energy that flows depends on the time and the contact between the substances of objects. Indeed, objects need to be in contact or close to each other for heat to transfer, and the time needs to be enough for the process to occur. For example, if you place a pot over the fire just for a few seconds it is likely the heat transferred is minimal, which does not occur if you leave the pot more time. At the same time if the pot is in close contact with fire more heat will be transferred.-

When a parallel beam of light passes through a convex lens, the rays become farther from one another when the come out. This process of rays is called ''to diverge''. The concave lens makes rays of light diverge, so it is called diverging lens.

The pressure is 0.00038 Pa/m, and the power lost to friction per meter of pipe is approximately \(2.28 * 10^-7 W/m.\)

To determine the pressure drop per meter of pipe and the power lost to friction, we need to calculate the friction factor using the Moody chart and the Darcy-Weisbach equation. The Darcy-Weisbach equation is:

ΔP = \(f * L * (v^2) / (2 * g * d)\)

where ΔP is the pressure drop per meter of pipe, f is the friction factor, L is the length of pipe, v is the velocity of the water, g is acceleration that occurs because of gravity and d is pipe's diameter.

We can use the Moody chart to find the friction factor, f, based on the Reynolds number, which is a measure of the fluid flow regime. For a smooth plastic pipe, the Reynolds number can be calculated as:

Re = (v * d) / ν

where ν is the kinematic viscosity of the water, which is approximately \(0.000001 m^2/s\) at 20°C.

Once we have the Reynolds number, we can find the friction factor from the Moody chart. For a Reynolds number of approximately 2200, the friction factor for a smooth plastic pipe is approximately 0.022.

Plugging the values into the Darcy-Weisbach equation, we find that the pressure drop per meter of pipe is:

ΔP = \((0.022) * (1 m) * (0.09 m/s)^2 / (2 * 9.8 m/s^2 * 0.2 m)\) = 0.00038 Pa/m

To calculate the power lost to friction, we can use the equation:

P = ΔP * Q

where P is the power lost to friction and Q is the flow rate, which can be calculated as:

Q = A * v = \((pi/4) * d^2 * v = (pi/4) * (0.2 m)^2 * (0.09 m/s)\)= \(0.0006 m^3/s\)

Plugging the values into the power equation, we find that:

P = ΔP * Q = (0.00038 Pa/m) * (0.0006 \(m^3/s\)) = \(2.28 * 10^-7 W/m\)

Answer:

Explanation:

In physics, work can be described as force multiplied by the displacement of the object (distance caused by the force acted on the object).

Work is a form of energy, therefore, it is measured in joules.

If Alex pushed on an object with 10N of force, and the object moved 2 meters, the work of Alex will be equal to:

W = Ft

W = 10N * 2m

W = 20 Joules

But, if we have John, that pushed on an object with 2N of force, but, since the object was way smaller, therefore it had way less inertia, the object moved a distance equal to 10 meters. Let's also calculate his work.

W = Ft

W = 2N * 10m

W = 20 Joules

And we got the same result.

Work can also be used to calculate power.

Power is equal to P = Work / time

It can also be written as P = delta Work / delta time

Power is measured in joules per second.

With power you can make the difference between someone that got a 2 kg object up in 2 second, and someone that got a 2 kg object up in 5 second.

The more powerful one would be the one who managed to make the same work in less time.

Hope it Helped!

Work is described as: the measure of energy transfer resulting from the application of force over a displacement.

In the field of physics, work is most accurately defined as the outcome of multiplying the force exerted on an object by the distance the object is displaced in the same direction as the force.

This calculation serves to quantify the energy transferred to or from the object. For instance, if an individual applies a 50 Newton force to push a box across a 5-meter distance in the force's direction, the work done on the box would equal 250 Joules (50 N × 5 m).

More information is needed to provide a specific answer. Please provide additional context or data related to the initial velocity of the baseball.

To find the initial velocity of the baseball, we can use the kinematic equations of motion. Since the baseball is thrown at an angle, we need to break down the initial velocity into its x, y, and z components. We know that the initial height of the baseball is 1.8 meters, and the time it takes to reach its maximum height is 1.0 seconds. From this, we can calculate the vertical component of the initial velocity using the equation vf = vi + gt, where vf = 0 m/s, vi is the initial velocity, g is the acceleration due to gravity \((-9.8 m/s^2\)), and t is the time.

Solving for vi, we get vi = 9.8 m/s.

To find the horizontal component of the initial velocity, we can use the equation\(x = vit + 1/2at^2\), where x is the distance travelled in the x-direction (which is 18 meters), vi is the initial velocity in the x-direction, a is the acceleration in the x-direction (which is 0 m/s^2 since there is no horizontal force acting on the ball), and t is the time of flight (which we can calculate using the time it takes for the ball to reach its maximum height). Solving for vi, we get vi = x/t = 18/2.0 = 9.0 m/s. So the initial velocity of the baseball can be expressed as <9.0, 9.8, 0> m/s, where the x-component is 9.0 m/s (to the right), the y-component is 9.8 m/s (upward), and the z-component is 0 m/s (since there is no initial velocity in the z-direction).
