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.
Hello!
I'm just going to ignore the name of the building and just do the math
1 foot is equivalent to 0.3048 meters
if the building is 1368 feet tall, multiply it by 0.3048 to get 416.9664 meters
I hope this helps, and have a nice day!
Answer:
C) Amplitude.
Explanation:
By definition, the amplitude of wave is defined as the distance from the rest position to the highest or lowest point of the wave.
The highest and lowest points of the wave are called crests and troughs respectively; Therefore, the amplitude of the waves is also said to be the height of the wave from its rest position to its crest—and also the height of the from the rest position it its trough.
This means Choice C (amplitude) is the correct term used to describe the height of a wave from its rest position to its crest.
<em>P.S: Choice A, the crest height, can also be the correct term, but the term ''amplitude'' is often used and is more technical. </em>
Answer:
273 Kelvin
Explanation:
If -273 Celsius is 0 Kelvin, then 273 Kelvin will be 0 Celsius.
Answer:
<em>The pressure given by the water at the bottom is 58,800 Pa</em>
Explanation:
<u>Pressure Exerted by a Column of Liquid
</u>
The pressure P exerted by a column of liquid of height h and density ρ is given by the hydrostatic pressure equation:
P = ρgh
Where ρ is the density of the liquid, g is the acceleration of gravity g=9.8m/s^2, and h is the height of the column of liquid.
The height of water in a well is h=6 m. The density of water is a known quantity:
![\rho = 1,000\ kg/m^3](https://tex.z-dn.net/?f=%5Crho%20%3D%201%2C000%5C%20kg%2Fm%5E3)
Calculating P:
P = 1,000*9.8*6
P = 58,800 Pa
The pressure given by the water at the bottom is 58,800 Pa
