Base units for mass, length, time, and charge, and the number 10. All metric units, quantities, and operations are combinations of these.
Example: 1 micro-Newton (a tiny force) is 1 kilogram-meter per second squared times 10^-6.

Answer:
Because liquids and solids are denser than gasses.
Explanation:
Solids and liquids are denser than gasses making it easier for things like sound to conduct through them. Being dense contributes to a better conduction because the particles and such within the solid or liquid are closer together which allows for things like sound to travel at a much faster rate because they're so much easier to vibrate.
A testable question is something you need data for, ex: if i bounce a bouncy ball from larger heights, how high will it fly? it can't be just a regular yes or no question
