Can you please answer this fast this is due today and its on study island!!! Part of the rock cycle takes place under the Earth's surface. What provides the energy for this part of the rock cycle?
A.
potential energy from the Moon's gravitational influence
B.
heat energy from the Earth's interior
C.
kinetic energy from Earth's angular momentum
D.
light energy from the Sun

answer: hey stupid

what the hell you doing i need you at my house

explanation: it's me king omoregie

it is easily magnetized.

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.
