The forces of the tides on lo are strong enough to push the rocks of lo on top of each other. This constant rubbing and grinding creates enough heat
and pressure to cause new minerals to form. This makes lo one of the mos
geologically active places in the solar system.
What are the tidal forces acting on lo most similar to in the geology of the
Earth?
A. the formation of metamorphic rocks
B. our planet's molten core
C. mudslides after earthquakes
D. the accretion of sedimentary rocks
Tyne answer here:

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.

i already answered it by 34/s

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
