Answer:

Photovoltaic detection is a technique that converts light into electrical energy. It is a process that involves the use of a photovoltaic cell, which is made up of semiconductor materials, to generate an electric current when exposed to light.

The photovoltaic cell absorbs the photons of light, which then knock electrons out of their orbits, creating a flow of electricity. The amount of electricity produced is proportional to the intensity of the light. The photovoltaic cell is commonly used in solar panels to generate electricity from sunlight. The efficiency of the photovoltaic cell is dependent on several factors, including the type of semiconductor material used, the purity of the material, and the thickness of the cell.

The photovoltaic cell has many applications, including in solar power generation, telecommunications, and remote sensing. The technique of photovoltaic detection is an important area of research, as it has the potential to provide a clean and renewable source of energy that can help mitigate climate change.

Answer:

v = 1.098 m/s

Explanation:

Given that,

A person walks 750m due north then 250 m due east of the entire walk takes 12 min.

We need to find the average velocity of the person.

Displacement,

\(d=\sqrt{750^2+250^2} \\\\d=790.56\ m\)

Average velocity = displacement/time

\(v=\dfrac{790.56\ m}{12\times 60\ s}\\\\v=1.098\ m/s\)

So, the average velocity of the person is 1.098 m/s.

Vessel Mass Acting Downward (mg)

Bayonet Force Acting Above Vessel (Fb)

This force is called buoyancy. Buoyancy pushes objects up. Gravity exerts a downward force on an object determined by the object's mass. Therefore, if the downward force exerted by gravity on an object is less than the buoyant force the object floats.

Since the buoyant force on the body and the weight of the body are equal and opposite, the net force on the body is zero, giving the body a net force to levitate. The wind force acting on a sail moving a boat is an example of Newton's third law of motion. That is, every action has an equal and opposite reaction. But the relationship between force and motion is not as simple as the wind blowing just behind the sails propels the ship forward.

Answer:

C

Explanation:

a) The acceleration of gravity on Vulcan is approximately 9.89 m/s^2.

b) It takes approximately 3.80 seconds for the package to reach the astronauts.

c) the astronaut would have to exert a force of approximately 108 N upwards to catch the package.

a) To find the acceleration of gravity on Vulcan, we can use the formula:

g = G * M / r^2

where G is the gravitational constant (6.674 x 10^-11 N*m^2/kg^2), M is the mass of Vulcan, and r is the radius of Vulcan.

Substituting the given values, we get:

g = (6.674 x 10^-11 N*m^2/kg^2) * (5.78 x 10^23 kg) / (4.37 x 10^6 m)^2

g ≈ 9.89 m/s^2

Therefore, the acceleration of gravity on Vulcan is approximately 9.89 m/s^2.

b) We can use the kinematic equation:

y = y0 + v0t + 1/2 at^2

where y is the final position (55 m), y0 is initial position (0), v0 is velocity (12 m/s downwards), a is the acceleration of gravity (9.89 m/s^2), and t is time we want to find.

Substituting:

55 m = 0 + (12 m/s)t + 1/2 (9.89 m/s^2)t^2

Simplifying and solving for t, we get:

t ≈ 3.80 s

Therefore, it takes approximately 3.80 seconds for the package to reach the astronauts.

c) To find the amount of force the astronaut would have to exert upwards to catch the package, we can use the work-energy principle:

Work = ΔKinetic Energy

The initial kinetic energy of the package is:

KEi = 1/2 mv0^2 = 1/2 (1.8 kg) (12 m/s)^2 = 129.6 J

Since the package comes to rest, its final kinetic energy is zero, so the change in kinetic energy is:

ΔKE = 0 - 129.6 J = -129.6 J

The work done by the astronaut is equal in magnitude but opposite in sign to ΔKE, so:

Work = 129.6 J

The force exerted by the astronaut is:

F = Work / d

where d is the distance over which the force is applied (the distance the astronaut's arms move as he catches the package, which we assume to be 1.2 m).

Substituting the given values, we get:

F = (129.6 J) / (1.2 m) ≈ 108 N

Therefore, the astronaut would have to exert a force of approximately 108 N upwards to catch the package.

An independent-measures t hypothesis test is appropriate when - d.  there are two separate samples containing different subjects.

When you wish to compare the means of just two groups—no more, no less—use an independent samples t test! This test is typically used to detect whether two population means differ. This process employs samples to infer information about populations, making it an inferential statistical hypothesis test. The two sample t test is another name for the independent samples t test. You can reject the null hypothesis if the p-value is less than your threshold for significance (for example, 0.05). The two means difference is statistically significant. The data from your sample is convincing enough to support the conclusion that the two-population means are not equal.

Based on the information provided in the second paragraph of "On a Mountain Trail," the correct option would be "The pack surrounding the sleigh is a very real threat to the two men on the trail." The correct option is C.

In the second paragraph, it is mentioned that the wolves had stopped running and were now "moving at a dogtrot, leisurely and methodically encircling the sleigh." This description implies that the wolves are actively surrounding the sleigh, which suggests a potential threat to the two men on the trail. The word "encircling" indicates a deliberate and coordinated action by the wolves, which implies predatory behavior.

Now let's examine why the other options are not true:

A. The surrounding pack should not be concerning to the two men.

This option is not true because the description in the paragraph clearly implies that the pack of wolves surrounding the sleigh is a cause for concern.

B. The wolves will eventually tire and will return to the safety of the underbrush.

This option is not supported by the information provided in the paragraph. There is no mention of the wolves becoming tired or retreating to the safety of the underbrush. The description implies that the wolves are actively encircling the sleigh, indicating an ongoing threat.

D. Once a sleigh is surrounded by a pack of wolves, there is no chance for human survival.

This option is an extreme statement and goes beyond the information provided in the paragraph. The paragraph does not provide any conclusive information about the chances of human survival in such a situation. It simply describes the current state of the wolves surrounding the sleigh, but it does not make a definitive statement about the outcome for the two men.

Answer:

The graph of the velocity of an object in free fall would look like a straight line sloping downward. As the object falls, its velocity increases at a constant rate, so the graph of its velocity versus time will be a straight line with a negative slope. This is because acceleration due to gravity is a constant -9.8 meters per second squared, so the velocity of a free-falling object will increase by 9.8 meters per second every second.

Therefore, the graph that shows the change in velocity of an object in free fall is a straight line with a negative slope. Here is an example of such a graph:

Net force applied on the soccer ball was approximately 250 N (newtons) when it was kicked by the player.

We use Newton's second law of motion, which states that net force (F_net) applied to an object is equal to the product of its mass (m) and acceleration (a):

F_net = m * a

In this case, mass of the soccer ball is given as  0.5 kg and the acceleration is 500 (m)/(s²), so:

F_net = 0.5 kg * 500 (m)/(s²) = 250 N

Using a tube as a filter to reduce the amplitude of sounds in various frequency ranges relies on manipulating resonance and destructive interference to achieve the desired attenuation.

A tube can be used as a filter to reduce the amplitude of sounds in various frequency ranges through a phenomenon called resonance. When a sound wave travels through a tube, it encounters resonant frequencies at which the tube's length corresponds to an integer multiple of the sound's wavelength. At these resonant frequencies, constructive interference occurs, resulting in an amplification of the sound. To use a tube as a filter, it is necessary to exploit the destructive interference that occurs at certain frequencies. This can be achieved by designing the tube's length and shape to create resonant frequencies that coincide with the frequencies to be attenuated. When the sound wave encounters these resonant frequencies, destructive interference takes place, causing a reduction in the sound's amplitude. By carefully selecting the dimensions of the tube, it is possible to create a series of resonant frequencies that correspond to specific frequency ranges. This allows the tube to act as a filter, attenuating the amplitudes of sounds within those ranges while having less impact on sounds outside the targeted frequencies.
