1000 Pa.
1000000 Pa.
In an open container of liquid, the pressure at a point in the liquid depends on:
The density of the liquid and depth.
The type of container.
The surface area of the container.
The temperature of the liquid.
In a fluid at rest, the pressure at a given point is:
Dependent on the shape of the container.
Zero.
Only applied vertically.
Equal in all directions.
Which of the following correctly describes the effect of the density of a fluid on pressure?
Higher density increases pressure.
Higher density has no effect on pressure.
Higher density only affects volume, not pressure.
Higher density decreases pressure.
