When the velocity of a liquid flowing steadily in a tube increases what happens to the pressure

Bernoulli's Principle states that as the speed of a moving fluid increases, the pressure within the fluid decreases. The Bernoulli's Principle explains the behavior of an ideal fluid passing through a pipe or enclosed passageway such a pump.

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
