What does the heliocentric view of a solar system imply

   Planets revolve around the Sun

Explanation:  The heliocentric model implies that all the planets of the solar system, therefore, the Earth, together with their satellites orbit the Sun. This means that the Sun is the center of the solar system, not the Earth as it was believed to be under the influence of the teachings of the Church in the Middle Ages. The reason for this is that gravitational force acts between celestial bodies as a consequence of the huge masses that celestial bodies have.  Since the Sun has a much larger mass than all the planets and satellites of the solar system, the greatest influence, that is, the attractive force, acts from the Sun, and all planets therefore revolve around the Sun. Also, the Earth has a larger mass than the Moon, so the Moon orbits the Earth, but together with the Earth it orbits the Sun because of the huge mass of the Sun.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

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.
