Construction, like building a home/building, digging, like in a mine, and opening a soda can, where the part to open is a lever.
Answer:
5. dispersion
6. 49.8°
Explanation:
5. Dispersion is the name given to the phenomenon of light of different wavelengths being bent differently. A rainbow is the result of light from a point source (the sun) being spread out by wavelength (color), a nice example of dispersion.
___
6. n = 1.31 is the ratio of the sine of the angle of refraction to the sine of the angle of incidence (for light passing to a medium of n = 1). When the angle of refraction is 90°, the angle of incidence is the "critical angle." So, ...
sin(90°)/sin(critical) = 1.31
critical angle = arcsin(1/1.31) ≈ 49.8°
<h2>C
omets are made of Chunks of rock, gas, Ice, and dust. The Answer is A and C.</h2>
Explanation:
Comets is one of the main types of space rocks. Recent researchers has termed Comets as 'dirty snowballs' of space, that contains ice, rock, gas and dust. The solid center of the comet is less than 10 kilometers across.
Comets are believed to have originated beyond Neptune and Pluto. It is called the Oort Cloud that surrounds the solar system.
It carries carbon dioxide, methane, ammonia, and many more gases. According to Astronomers, comets are assumed to be the leftovers of the material that was initially the part of solar system about billion years ago.
