When a fluid fills a closed container, it exerts pressure
only on the bottom of the container
only on the sides of the container
only on particles within the fluid
everywhere inside the container
Fluids exert pressure because they
contain force particles
are confined to small area
have constantly moving particles
all of these are correct
