Answer: b. mirages

Explanation:

A mirage is an optical illusion that occurs naturally due to refraction in the atmosphere. This phenomenon occurs especially in environments where the air exhibits large variations in its temperature, causing each of the layers with different temperatures to have a different index of refraction and therefore, the light rays will be diverted to the colder side.

Then, when this happens, displaced images of distant objects, or in the sky, are produced. In fact, sometimes it seems that distant objects are reflected on a liquid surface that is not real.

Question ~ What's the difference between the American and National Baseball Leagues?

Answer ~ Major League Baseball is divided into two leagues with long and storied histories. See more sports pictures

Most people know that Major League Baseball is divided into two separate leagues: 1The American League and the National League. The National League, formed in 1876, is the older of the two leagues that make up the professional Major League Baseball organization in the United States and Canada. The main difference in the two is that the American League uses the designated hitter rule to replace pitchers during at-bats, and the National League does not.

Alexander Cartwright, an architect and sportsman in New York City, is widely recognized as the father of modern organized baseball. He was instrumental in founding the first organization devoted to playing baseball, the Knickerbocker Base Ball Club, in 1845. He wrote 20 rules about the field layout and how the game was played. The most important one was that players had to be tagged or forced out rather than having the ball thrown at them [source: Dickey]. Of course, the rules were modified as the game evolved, but Cartwright gave us the essence of baseball.

Three differences between the American League and National League in Baseball include the use of the DH rule by the AL but not traditionally by the NL, the former impact of the All-Star Game on World Series home-field advantage, and the integration of Interleague play.

The American League (AL) and the National League (NL) are the two leagues that make up Major League Baseball (MLB). Historically, there have been several differences between them. Here are three distinct differences:

These differences contribute to unique strategies and fan experiences within each league.

Refer to the diagram attached (created with GeoGebra). Consider the 5 N force in two directions: parallel to the 8 N force and normal to the 8 N force.

The sum of forces on each direction will be the resultant force on that direction:

Apply the Pythagorean Theorem to find the magnitude of the resultant force.

[tex]\displaystyle \Sigma F = \sqrt{{(8 + \dfrac{5\sqrt{2}}{2})}^2 + {(\dfrac{5\sqrt{2}}{2})}^2} = 12.1\;\text{N}[/tex] (3 sig. fig.).

The size of the angle between the resultant force and the 8 N force can be found from the tangent value of the angle. Tangent of the angle:

[tex]\displaystyle \dfrac{\Sigma F_\text{Normal}}{\Sigma F_\text{Parallel}} = \dfrac{8 + \dfrac{5\sqrt{2}}{2}}{\dfrac{5\sqrt{2}}{2}} \approx 0.306491[/tex].

Find the size of the angle using inverse tangent:

[tex]\displaystyle \arctan{ \dfrac{\Sigma F_\text{Normal}}{\Sigma F_\text{Parallel}}} = \arctan{0.306491} = 17.0\textdegree[/tex].

In other words, the resultant force is 17.0° relative to the 8 N force.

Answer:

1 average 2 subtract.

Explanation:

a). add

b). subtract.

We measure temperature of matters with a device called thermometer. There are three types of thermometer, Celsius Thermometer, Fahrenheit Thermometer and Kelvin Thermometer.

Non-examples of temperature include instances like inaccurately implying ratios in temperature, thinking an increase in internal energy always results in an increase in temperature, and misconceptions about absolute zero in temperature scales.

A non-example of temperature could be simply understood as a situation or instance where temperature doesn't play a significant role, or where the notion of temperature as we usually perceive it, does not apply. For instance, the concept of ratio or multiplication in temperature such as saying 80 °C is four times as hot as 20 °C is a non-example, because there's no meaning to the ratio of 80 to 20 (or four to one) in the context of temperature. Another non-example is the assumption that increasing internal energy of a system necessarily increases its temperature; this is not always true. The temperature does not change when a substance changes from one phase to another, like during the melting of ice. This can be accomplished by adding heat or doing frictional work without changing temperature.

The concept of absolute zero, where there is zero molecular motion, is another perception which sometimes confounds the casual understanding of temperature, especially in cases like Celsius (C) and Fahrenheit (F) temperature scales where 0 degrees does not mean absence of heat because temperatures lower than zero exist and are in fact colder. Thus, these cases represent non-examples of common understanding of temperature.

I just had this question on my test, the answer is C.

Answer:

The new force will decrease to one sixth the original value.

Explanation:

It is given that,

One charge is decreased to one-third of its original value, and a second charge is decreased to one-half of its original value.

Let, [tex]q'_1=\dfrac{1}{3}q_1[/tex] q₁ is the charge 1

[tex]q'_2=\dfrac{1}{2}q_2[/tex] q₂ is the charge 2

Initially, the electrical force between the charges is given by :

[tex]F=k\dfrac{q_1q_2}{r^2}[/tex]...........(1)

Let F' is the new force i.e.

[tex]F'=k\dfrac{q'_1q'_2}{r^2}[/tex]

So,

[tex]F'=k\dfrac{\dfrac{1}{3}q_1\times \dfrac{1}{2}q_2}{r^2}[/tex]

[tex]F'=\dfrac{1}{6}k\dfrac{q_1q_2}{r^2}[/tex]

[tex]F'=\dfrac{1}{6}F[/tex]  (from equation 1)

Hence, the new force will decrease to one sixth the original value.

Answer:

2 m/s

Explanation:

The impulse exerted by the obstacle on the block is equal to the change in momentum of the block:

[tex]I=\Delta p = -6 Ns[/tex]

where we put a negative sign because the direction of the impulse is south, which is opposite to the initial direction of travelling of the block (north).

The change in momentum is also equal to

[tex]\Delta p = m (v-u)[/tex]

where

m = 3 kg is the mass of the block

v is the final velocity

u = +4 m/s is the initial velocity

Solving the equation for v, we find the final velocity of the block:

[tex]v=u+\frac{\Delta p}{m}=+4 m/s+\frac{-6 Ns}{3 kg}=+2 m/s[/tex]

and the positive sign means the direction is still north.

Yes, the statement is true. When white light passes through a prism, red light is the least deviated because it has the longest wavelength among the visible light spectrum. This dispersion phenomena breaks white light into its constituent colors.

The statement 'When white light passes through a prism, red light is least changed in direction' is True. This is because when white light, which is made up of different colors or wavelengths, is refracted through a prism, it experiences dispersion. As a result, different wavelengths of light are bent by different amounts. This phenomenon occurs because different frequencies of light have different refractive indices for a given material. Therefore, each color follows a slightly different path through the prism. Red light has the longest wavelength among the visible light spectrum and is refracted or bent the least compared to other colors such as violet, which has the shortest wavelength and is refracted the most. This explains why when we observe the dispersion of white light through a prism, such as in Newton's rainbow experiment, we see red light emerge at the least deviated angle, and violet light at the most deviated angle.

Answer:

Unbalanced, 5N to the right.

Explanation:

The product of (wavelength) x (frequency) is always the same number ... the wave's speed.  

So if the wavelength is somehow reduced to  1/4  its original length, the frequency is immediately multiplied by 4 .  That's the only way their product can remain the same.

The frequency increases by a factor of four when the wavelength is lowered by a factor of four.

Frequency is defined as the number of repetitions of a wave occurring waves in 1 second.

Frequency is given by the formula as,

[tex]\rm v = \lambda \times f[/tex]

If a wave travels at a constant speed the e frequency is inversely proportional to the wavelength.

if the wavelength is reduced by a factor of 4 then the frequency increases by a factor of 4.

Hence, the frequency increases by a factor of 4.

Since you didn't add any answer choices I will explain the frequency of a wave the best I can.

The frequency of a wave is the distance between one crest and another. Frequency can affect the energy of a wave. If the crests in a wave are close together, than the frequency of said wave is high as well as the energy. If they are far apart, than the frequency will be low and the energy will also be low.

Hope this helped.

Wave frequency is the number of waves that pass a fixed point in a given amount of time.

The number of vibrations counted per second is called frequency. A wave is a group of vibrations that are referred to as energy. The bottom node is known as the crest, and the top node is known as the trough.

The frequency of an alternating current is the number of full cycles per second. The hertz, also known as Hz, is the accepted unit of frequency. The frequency of a current is 1 Hz if one cycle is completed per second; 60 cycles per second equals 60 Hz.

A often utilized factor in relation to the wave is frequency. Let's say we need to determine the wave's frequency and the wave moves at a certain pace. The wavelength and velocity of the light wave are also used to calculate the number of cycles the wave has completed in one second. The frequency term is frequently taken into account in relation to the sound wave.

Explanation:

1. When the distance is doubled: [tex]3\cdot 10^{-7}N[/tex]

The electrostatic force between two charges is given by:

[tex]F=k\frac{q_1 q_2}{r^2}[/tex]

where

k is the Coulomb's constant

q1 and q2 are the two charges

r is the distance between the two charges

The initial force between the two charges is [tex]F=1.2\cdot 10^{-6}N[/tex]. In this part of the problem, the distance between the two charges is doubled, so we can write

[tex]r'=2r[/tex]

And substituting into the formula, we find the new force:

[tex]F'=k\frac{q_1 q_2}{r'^2}=k\frac{q_1 q_2}{(2r)^2}=\frac{1}{4}k\frac{q_1 q_2}{r^2}=\frac{F}{4}[/tex]

So, the force is reduced to 1/4 of its original value. Therefore, it is

[tex]F'=\frac{1.2\cdot 10^{-6} N}{4}=3\cdot 10^{-7}N[/tex]

2. When the distance is halved: [tex]4.8\cdot 10^{-6}N[/tex]

The initial force between the two charges is [tex]F=1.2\cdot 10^{-6}N[/tex]. In this part of the problem, the distance between the two charges is halved, so we can write

[tex]r'=r/2[/tex]

And substituting into the formula, we find the new force:

[tex]F'=k\frac{q_1 q_2}{r'^2}=k\frac{q_1 q_2}{(r/2)^2}=4k\frac{q_1 q_2}{r^2}=4F[/tex]

So, the force is quadrupled. Therefore, it is

[tex]F'=4(1.2\cdot 10^{-6} N)=4.8\cdot 10^{-6}N[/tex]

3. When the distance is tripled: [tex]1.33\cdot 10^{-7}N[/tex]

The initial force between the two charges is [tex]F=1.2\cdot 10^{-6}N[/tex]. In this part of the problem, the distance between the two charges is tripled, so we can write

[tex]r'=3r[/tex]

And substituting into the formula, we find the new force:

[tex]F'=k\frac{q_1 q_2}{r'^2}=k\frac{q_1 q_2}{(3r)^2}=\frac{1}{9}k\frac{q_1 q_2}{r^2}=\frac{F}{9}[/tex]

So, the force is reduced to 1/9 of its original value. Therefore, it is

[tex]F'=\frac{1.2\cdot 10^{-6} N}{9}=1.33\cdot 10^{-7}N[/tex]

Answer:

The last part on the right side of the diagram

Explanation:

Im on plato and just got it right :)

The last part on the right end of the given wave has the highest frequency.

The frequency can be defined as the number of oscillations of a wave in 1 second. The wavelength can be described as the distance between the two crests or troughs on a wave that is separated by a distance.

For periodic waves, media in which the wave speed is independent of frequency, therefore the frequency has an inverse relationship to the wavelength.

[tex]{\displaystyle f={\frac {v}{\lambda }}[/tex]

In electromagnetic waves in vacuum, then v = c, where c is the speed of light:

[tex]{\displaystyle f={\frac {c}{\lambda }}[/tex]

When monochromatic waves propagate from one medium to another, their frequency will remain the same.

Frequency can be defined as the number of occurrences of a repeating event per unit of time. Frequency can be measured in hertz (Hz) which is generally equal to one event per second.

Therefore, the part at the very right of the wave has the highest frequency.

Final answer:

Reflection can be seen when light bounces off a body of water, when it reflects from a mirror, or even off rough surfaces like sidewalks, where the light is scattered rather than forming a clear image.

Explanation:

An example of reflection can be observed when looking at the surface of a body of water. From above, the water reflects light back into the air, providing us with the visible image of our surroundings. A familiar everyday experience is observing light reflection from a mirror, where light rays hit the mirror and bounce off at the same angle, forming a clear image. Surfaces like sidewalks also demonstrate reflection; the rough texture scatters the light in various directions, which is why we do not see a distinct image of the sun, but we still perceive the concrete due to reflected light.
