Hi I need help my home work says can you change use the sun energy to produce the food in this sandwich the cheese came out from the milk I'm a cow that a crash that took energy from the sun for explain fill in the other chain

Food chain: cheese a product of the sun.

Explanation:

Food chain: The energy taken from the sun through photosynthesis enables plants to exist and grow.

The animal like cow takes chemical energy from plants by eating plants product.

The cow is able to produce the milk because of the energy that has been taken from the plant.

Since the cheese came out from the milk, we can therefore conclude that the food is initially a product of the sun.

this means that the temperature of both substances will be equal

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.
