The theory of color vision proposed by thomas young that says color perception results from mixing three distinct color systems is called the _____.

Answer: Refractors and absorbers.

Explanation: Almost every material takes in (at least a fraction) of a wave when a wave hits it, where some frequencies or wavelengths may have a bigger percentage taken in.

For electromagnetic waves, a perfect conductor will only reflect the incident wave, and every other case will absorb a part and reflect others.

The type of materials that are "good" by absorbing/transmitting waves are called refractors.

There are other materials called absorbers, but those ones are used for "particles", and you may recall that the light, an electromagnetic wave, can also be viewed as a particle.

Answer:

final relaxed state is m = 3

Explanation:

As we know that due to transition of electron the wavelength emitted is given as

[tex]\frac{1}{\lambda} = Rz^2(\frac{1}{m^2} - \frac{1}{n^2})[/tex]

now we know that

[tex]\lambda = 1005 nm[/tex]

now we have

[tex]\frac{1}{1005\times 10^{-9}} = 1.01\times 10^7(\frac{1}{m^2} - \frac{1}{49})[/tex]

now by solving above equation for m we will have

m = 3

so the final relaxed state is m = 3

Answer:

Students could slip on the liquid.

Explanation:

Angle; θ ≈ 31. 5°

This question involves centripetal motion and angle of elevation.

This means, from centripetal motion we can write the force as;

F•sin θ = mv²/r - - - (1)

Where θ is the angle relative to the horizontal if the wings are banked.

r is radius

v is speed

F•cos θ = mg  - - - (eq 2)

(F•sin θ)/(F•cos θ) = (mv²/r)/mg

tan θ = v²/rg

Plugging in the relevant values L, we have;

tan θ = 300²/(15000 × 9.8)

tan θ = 0.6122

θ = tan^(-1) 0.6122

θ ≈ 31. 5°

A star that radiates most strongly at 400 nm, a shorter wavelength than the Sun's peak at 550 nm, would be hotter according to Wein's Law.

The question concerns the relationship between the temperature of a star and the wavelength at which it radiates most strongly, based on Wein's Law. The Sun, with a surface temperature of approximately 5,800 K, radiates most strongly at about 550 nm, which is in the visible spectrum near the green-yellow part. A star that radiates most strongly at 400 nm, which is closer to the violet part of the spectrum, would be hotter than the Sun.

According to Wein's Law, the peak wavelength of radiation emission (a) is inversely related to the temperature of the emitting body (T), such that a * T = constant (where the constant is approximately 3 x 106 nm·K). Since 400 nm is shorter than 550 nm, the star with a peak emission at 400 nm must have a higher temperature than the Sun to satisfy the inverse relationship described by Wein's Law.

The statement is false that wherever you see the stem, fog, or clouds you are seeing water in a liquid state.

In the Earth's atmosphere, clouds are visible collections of minute water droplets or ice crystals. The size, form, and color of clouds vary widely. They can appear big and lumpy or delicate and airy.

Because the small water droplets inside of clouds are closely packed, they typically have a white appearance because they reflect most of the sunlight that strikes them. Our eyes interpret the combined spectrum of sunlight as white. Clouds become darker as rain approaches because the water vapor is condensing into raindrops and widening the spaces between them. It reflects less light. The rain cloud looks to be gray or black.

Therefore, the given statement is false.

The San Andreas fault zone in California is an example of a transform   boundary. The movement of tectonic plates relative to each other make the plate boundaries.

Plate boundaries are region between two tectonic plates. Where the plates interact each other by moving past each other or slides away. There are three types of plate boundaries namely, convergent, divergent and transform plate boundaries.

In geology, a strike-slip fault is a crack in the Earth's crustal rocks when the rock masses slide past one another parallel to the strike. It is formed when a rock surface intersects with the surface or another horizontal plane.

The San Andreas Fault is thought to be the transform (strike-slip) border between two significant plates of the Earth's crust: the North American to the north and east and the Northern Pacific to the south and west. The San Andreas fault is a strike-slip fault because the Northern Pacific plate is passing the North American plate laterally in a northerly manner.

We can solve for the resultant x and y components by using the sine and cosine functions.

resultant x = 2.5 cos 35 + 5.2 cos 22 = 6.87 km

resultant y = 2.5 sin 35 + 5.2 sin 22 = 3.38 km

The resultant displacement is calculated using hypotenuse equation:

displacement = sqrt (6.87^2 + 3.38^2)

displacement = 7.66 km

The resultant angle is:

θ = tan^-1 (3.38 / 6.87)

θ = 26.20°

Therefore the magnitude and direction is:

7.66 km, 26.20° to the ground

To find the plane's total displacement, we calculate the horizontal and vertical components of each part of the journey, then combine these components. The magnitude is the hypotenuse of the triangle formed by the summed components, while the direction is the angle from the horizontal.

We can find the plane's total displacement by breaking the first and second parts of the journey into their respective horizontal and vertical components and then combining these components. Here's how we'll do it step-by-step:

The magnitude is the hypotenuse of the right triangle formed by the x_total and y_total components, and the direction is the angle that this vector makes with the positive x-axis, which is usually horizontal ground-level movement.

The statement that best describes the relationship between plants , animals and carbon cycle is : ( A ) Plants use carbon and release oxygen and animals release carbon and use oxygen.

In the carbon cycle plants absorb carbon dioxide from the atmosphere and energy from sunlight and water to produce its food ( photosynthesis ). during photosynthesis plants give back oxygen into the atmosphere which is inhaled by animals during respiration.

Animals take in oxygen while giving out carbon dioxide as  a waste product.

Hence we can conclude that the correct statement is plants use carbon and release oxygen and animals release carbon and use oxygen.

Final answer:

The gravitational force on Planet 2, which is four times more massive but orbits at three times the distance from a star compared to Planet 1, would be 4/9 of the gravitational force on Planet 1, according to Newton's law of universal gravitation.

Explanation:

The question pertains to the gravitational force exerted by a star on two different planets in orbit. According to the provided scenario, Planet 1 experiences a gravitational force denoted as f1. Planet 2 is four times as massive as Planet 1 and orbits at a distance that is three times larger from the star, resulting in gravitational force f2. To compare f1 and f2, one can use Newton's law of universal gravitation, which states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. For Planet 2, which has four times the mass (4M), but is at three times the distance (3d), the force of gravity, f2, can be calculated as follows:

f2 = (G * (4M) * M_star) / (3d)^2 = (4/9) * (G * M * M_star) / d^2

Where:

G represents the gravitational constant

M is the mass of Planet 1

M_star is the mass of the star

d is the original distance between Planet 1 and the star

Comparing f2 with f1, which is (G * M * M_star) / d^2, it becomes clear that f2 = (4/9)f1. Therefore, the gravitational force acting on Planet 2 is 4/9 that of the gravitational force acting on Planet 1.

Answer:

Visible light has higher energy than infrared light because visible light has higher frequencies.

Explanation:

higher frequencies have a higher amplitude in turn having more energy.

When forces are balanced, the object remains stationary.

When the force with which an object pushes down on the ground is equal and opposite to the force with which the ground pushes it up, the object will remain stationary. This is because the forces are balanced, resulting in no net force and therefore no motion.
