Someone in a car going past you at the
speed of 46 m/s drops a small rock from a
height of 2.2 m.
how far from the point of the drop will the
rock hit the ground? the acceleration due to
gravity is 9.8 m/s
2
.

the awnser is 46 because the square root of d in yo mouth is dis jis wit da stik on yo block cuz

Explanation:

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.
