A
2
Q
Give the properties of pressure on an object in a liquid
A
- Pressure exerted evenly across the whole surface in all directions
- The pressure creates forces against the surface
- These forces act ninety degrees to the surface
3
Q

A
Depth within the fluid and density of the fluid
4
Q
Formula for pressure within a liquid
A
Δp = change in pressure
ρ = density of the liquid
g = gravitational field strength
Δh = change in height of the column
