Pls help Answer the following three questions in the space below about your model rock and the real sedimentary rock sample. What processes were involved in the formation of your model? How is your model similar to the real sedimentary sample? How is your model different from the real sedimentary sample?

cant help you with that buddy,

tell you uncle and he'll help you.

he dealt with that back in the AD

Explanation:

i think its c if i'm wrong

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
