What is a thermal energy reservoir at high temperature that supplies energy in the form of heat called?

Solar radiation refers to the emission of energy, particularly in the form of electromagnetic waves, resulting from the fusion of hydrogen in the sun's core. These radiations have wavelengths that range from less than one nanometer to more than one kilometre. They are absorbed, reflected, or transmitted by different mediums, including glass covers of solar collectors.

The glass covers of solar collectors are designed to allow the passage of solar radiation to reach the underlying absorbing surfaces and prevent their losses due to convection, conduction, or radiation. When solar radiation is incident on the glass cover of a solar collector at a rate of 700 w/m2, it is transmitted through the glass in part, reflected in part, and absorbed in part.

The amounts of transmission, reflection, and absorption depend on the characteristics of the glass, such as its thickness, refractive index, and transparency. For instance, a thin, clear, and transparent glass with a low refractive index would transmit most of the solar radiation and reflect and absorb a small fraction of it. The absorbed solar radiation raises the temperature of the absorbing surface, which could be a fluid, a metal, or a semiconductor.

The heat thus generated can be used for various applications, such as heating, cooling, and electricity generation.  Thus, the solar radiation incident on the glass cover of a solar collector is transmitted through the glass, reflected in part, and absorbed in part to generate heat.

The ability to reliably measure temperature using an infrared temperature sensor or a thermal imaging camera depends critically on emissivity, which measures a material's capacity to radiate infrared energy from its surface.

The type of surface affects a surface's emissivity in addition to the material. A smooth and polished metal surface will have a low emissivity in contrast to a roughened and oxidized metal surface, which will have a high emissivity.

Answer:

Once the weighted end of the pendulum is released, it will become active as gravity pulls it downward. Potential energy is converted to kinetic energy, which is the energy exerted by a moving object. An active pendulum has the most kinetic energy at the lowest point of its swing when the weight is moving fastest.

Explanation:

A good analogy to this process in the case of gravity is throwing a bowling ball up in the air.

Analogy is a figure of speech used to compare two different things that have similar characteristics in order to explain a concept or idea. It is a form of extended metaphor and can be used to draw a comparison between two objects, phenomena, or events to help explain something unfamiliar by associating it with something more familiar.

Work must be done by the person throwing the bowling ball, and as a result, potential gravitational energy is stored in the ball. As it goes higher and higher in the air, it has more potential energy, as it is farther away from the ground. Just like two charges that are moved farther apart storing electric potential energy, when a bowling ball is thrown up in the air, it gains gravitational potential energy due to being further away from the ground.

To rotate a stubborn screw, it is best to use a screwdriver that has a long handle.

A long handle provides more leverage, making applying greater torque to the screw easier. This greater torque can help loosen the screw, especially if it is stuck or resistant.

A wide handle or a smooth handle may be more comfortable to grip, but they do not provide any mechanical advantage or extra leverage to help rotate the screw. Therefore, they are less useful than a long handle for removing stubborn screws.

Therefore, the best option for rotating a stubborn screw is a screwdriver with a long handle, which can provide the necessary leverage to loosen the screw.

Explanation:

Caty  ,  Use   the relativity formula for length.  ( they teach this in H.S. ? )  it's from my Modern Physics in college, A 300 level class  

L = \(L_{0}\)\(\sqrt{1-\frac{v^{2} }{c^{2} } }\)

L = 3  \(\sqrt{1-\frac{.95^{2} }{1^{2} } }\)

L = 0.9367496998  meters

L = 0.94 meters approx

For this use the formula:

d = Vo * t - (at^2) / 2

Clearing t:

t = d/(v + 0.5*a)

Replacing:

t = 5 m / (7.2 m/s + 0.5 * (-1.1 m/s²)

Resolving:

t = 5 m / (7.2 m/s + (-0.55 m/s²)

t = 5 m / 6.65 m/s

t = 0.75 s

The speed of the bucket tied to a rope, v = 5 m/s

The radius of the circle, r =2 m

We need to find the magnitude of the centripetal acceleration of the bucket. The formula for the centripetal acceleration is given by :

\(a=\dfrac{v^2}{r}\\\\a=\dfrac{(5)^2}{2}\\\\a=12.5\ m/s^2\)

So, the centripetal acceleration of the bucket is \(12.5\ m/s^2\).

Here,

Resistance = 11.7

Ampere = 0.3

Voltage = ?

Now,

R = V/A

11.7 = V/0.3

11.7*0.3 =V

V = 3.51

In the photoelectric effect, the maximum kinetic energy of the electrons ejected from the metal increases when the frequency of the incident light increases.

The photoelectric effect is a phenomenon where electrons are emitted from a metal surface when it is exposed to electromagnetic radiation, specifically light with sufficient energy. This process can be explained by the quantum theory of light, which states that light consists of packets of energy called photons. The energy of a photon is directly proportional to its frequency, as described by the equation E = hν, where E is the energy, h is Planck's constant, and ν is the frequency of the light.

When the frequency of the incident light is increased, the energy of the photons also increases. If the energy of the incoming photons is greater than the metal's work function (the minimum energy required to eject an electron), the electrons absorb the energy and are ejected from the metal surface. The remaining energy is converted into kinetic energy for the ejected electrons, leading to an increase in their maximum kinetic energy.

In summary, the maximum kinetic energy of electrons in the photoelectric effect is dependent on the frequency of the incident light. When the frequency of the light increases, the energy of the photons increases, and if it surpasses the metal's work function, the electrons are emitted with a higher kinetic energy.

Since the baseball is moving, it has kinetic energy.

Since the baseball has a certain height (it's not moving on the ground, it's moving above the ground), so it also has gravitational energy.

The ball itself has a certain temperature and has a molecular structure that holds energy, so the ball has internal energy.

And the ball has a certain deformation, that holds some elastic energy.

Therefore the correct option is B.

Answer:

Force = -10 Newton.

Explanation:

Given the following data;

Initial velocity = 8.5m/s

Final velocity = 7.5m/s

Time = 0.25 seconds

Mass = 2.5kg

To find the force exerted;

First of all, we would determine the acceleration of the ball;

Acceleration = (v - u)/t

Acceleration =(7.5 - 8.5)/0.25

Acceleration = -1/0.25

Acceleration = -4 m/s²

Now, to find the force exerted;

Force = mass * acceleration

Force = 2.5 * -4

Force = -10 Newton

Note: The force is negative because it is an opposite reaction.

Explanation:

The angle between e and E is 90 degrees, the cosine of the angle is zero, which means that the scalar product is also zero. In other words, e•E = 0 when e is a unit vector directed along an equipotential line.

If e is a unit vector directed along an equipotential line, then it is perpendicular to the electric field E at every point along that line. This is because equipotential lines represent a constant electric potential, which means that there is no change in potential along that line. Since the electric field is the negative gradient of the potential, it is always perpendicular to the equipotential lines. Therefore, the scalar product e•E between the unit vector e and the electric field E is zero. The scalar product is defined as the product of the magnitudes of the two vectors and the cosine of the angle between them. Since the angle between e and E is 90 degrees, the cosine of the angle is zero, which means that the scalar product is also zero. In other words, e•E = 0 when e is a unit vector directed along an equipotential line.

The availability of suitable nesting sites is one of the most important limiting factors for the purple martin bird population.  Building more birdhouses can help address this limiting factor and increase the size of the purple martin population in the area.

There are several limiting factors that can decrease purple martin populations, but one of the most important is the availability of suitable nesting sites. Purple martins are cavity-nesting birds, which means they require hollow spaces, such as tree cavities or specially designed birdhouses, to build their nests and raise their young. In areas where suitable nesting sites are scarce, the population of purple martins may be limited by the number of available nesting sites.

Therefore, by building more birdhouses, Latrice is addressing this limiting factor and helping to increase the size of the purple martin population in her area. Other limiting factors for purple martins may include the availability of food, the quality of habitat, and the presence of predators.
