Term
An immersed object displaces _______ of the fluid in which it is immersed. 

Definition


Term
A completely submerged object always displaces a volume of fluid equal to its own ___________. 

Definition


Term
Define: Archimedes’ principle 

Definition

Term
Give three principles of flotation. 

Definition
A. Object more dense than immersion fluid, it sinks. B. Object less dense than immersion fluid, it floats. C. Object equal in density of immersion fluid, it suspends. 


Term
A floating object displaces a weight of fluid equal to its own ______________. 

Definition


Term
Changes in pressure at any point in an enclosed fluid at rest are transmitted _______________ to all points in the fluid and act in all directions. 

Definition


Term
The hydraulic press is based on ________ principle 

Definition


Term
Pressure of a liquid at rest does/does not depends on the shape of the container. 

Definition


Term
Give me an Equation for pressure (due to a liquid). 

Definition
(Weight density)(depth) More explanation: Pressure = F/A which is Weight/Area Weight = weight density* volume so: Pressure = weight density*area*depth/area The area’s divide out giving us: Weight density * Depth
