6) A room has its walls aligned accurately with respect to north, south, east, and west. The north wall has an
area of 15 m the east wall has an area of 12 m, and the floor's area is 35 m? At the site the Earth's
magnetic field has a value of 0.60 G and is directed 50 below the horizontal and 70 east of north. Find the
fluxes through the north wall, the east wall, and the floor

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

where is the photo and the answer choices?

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.
