HELP PLEASE 100 POINTS Which direction will air flow: from areas of high pressure to low pressure OR areas of low pressure to high pressure?

See the explanation below.

Explanation:

The air will always move from a high pressure area to a lower pressure area, this can be easily deduced by the bernoulli equation, which tells us that the sum of the energy in point 1 must be equal to the energy in point 2. In order to better understand this equation an example will be shown.

In the figure we can see that the pressure at the point must be greater than the pressure at Point 2, so that air moves from Point 1 to point 2.

i think the answer would be reserve.

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.
