B. Both begins with "We, the People".

C. Both prohibits the collection of personal income taxes.

D. Both contains provisions on how citizens should register to vote.

The U.S. and Florida constitutions both have a preamble (an introduction that states the purpose and goals of government), articles (sections that describe the powers and functions of the government), and amendments (changes that have been made to the constitution).Explanation:

answer: i pick a

explanation:

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.
