Need answer how does porosity relate to permeability? a) the more porous, the less permeable b) the less porous, the less permeable c) porosity and permeability are not related d) the more porous, the less permeable

The correct answer is option B. The less porous the less permeable.

Explanation:

The porosity of a solid is a character that explains how much the space present between the grains of the solid. The rocks with more space in its grain have high porosity.

Permeability is the ability to pass a liquid through itself and it is closely related to the porosity. The more porosity the more permeability and vice verse.

Thus, the correct answer is option B.

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
