Answer:
C) Index of refraction
Explanation:
Index of refraction also known as refractive index is defined as speed of light in a vacuum divided by the speed of light in a given material.
The formula for Index of refraction is:
n = c ÷ v
where n represents Index of refraction,
c represents speed of light in a vacuum,
v represents speed of light in a given material.
The speed and direction of light changes when it moves from one medium to another. The change in direction is basically called refraction.
Answer:
Explanation:
helps recycle water
reduces the temperature extremes between day and night
recycles carbon dioxide and oxygen
protects the earth from harmful radiation
Answer:
the higher the ramp the less distance it will travel
Answer:
Option (A) and (F)
Explanation:
As the liquid cools down, it means the temperature decreases the density of the liquid increases in most o the cases.
Now the volume is inversely proportional to the density of substance so density increases.
