1.When a fluid fills a closed container, it exerts pressureImmersive Reader only on the bottom of the container only on the sides of the container only on particles within the fluid everywhere inside the container

It exerts pressure everywhere inside the container.

Explanation:

Pressure is the forelce exerted by a body per crossectional area,ie pressure is force/area.In fluid system an important law that explains the behavior of fluid in a closed vessel is the Pascal law.It state that a liquid in a containing vessel exerts pressure undiminished in all direction in a vessel and to all portion of the fluid.

the independent variable, or the one that is intentionally manipulated is the speed.

true tan speed = ang vel x radius
