A town is considering building a biodiesel power plant that would burn biomass to generate electricity. Which of the
following correctly lists an advantage and a disadvantage of this project?

a) Advantage: it could help get rid of unwanted waste. Disadvantage: there is no way to use the electricity created.

b) Advantage: it reduces dependence on fossil fuels. Disadvantage: it would emit pollution into the air.

c) Advantage: it is a commonly used energy source. Disadvantage: building the plant would attract new people to
the area.

d) Advantage: it would use energy from the sun and wind. Disadvantage: it is a non-renewable source of energy.

this is a good question! i'll do some research and come back when i have the answer!

time (seconds)

answer: 0 meters/second^2

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.
