<h2>
Answer: Diamond</h2>
Explanation:
This described situation is known as Refraction, a phenomenon in which the light bends or changes it direction when passing through a medium with a index of refraction different from the other medium.
In this context, the index of refraction is a number that describes how fast light propagates through a medium or material.
According to Snell’s Law:
(1)
Where:
is the first medium index of refraction (air)
is the second medium index of refraction (the value we want to know)
is the angle of the incident ray
is the angle of the refracted ray
Now, let's find from (1):
(2)
Substituting the known values:
Finally:
If we compare this result with the given table, the index of refraction value that is close to this number is diamond's index of refraction.
Therefore, the correct option is A: the material is diamond.
Answer:
0N
Explanation:
When you draw a free body diagram, You have a 7N arrow pointing left, and a 3N arrow pointing right. When you subtract the two, you still have a force of 4N on the left. However, seeing as how gravity is in play at a force of 4N, the two forces cancel out and you get 0N.
Answer:
A change of one degree Celsius = a change of one Kelvin, but a Celsius temperature is never equal to a Kelvin temperature. A change of 1 degree Fahrenheit equals a change of 5/9 = 0.56 degrees Celsius. To convert a Fahrenheit temperature to Celsius, subtract 32 and multiply by 5/9.
