density=force/volume

What is the density of water?

1.0 g/cm³

1.5 g/cm³

2.0 g/cm³

2.5 g/cm³

Air pressure does not crush objects on earth

because more air pushes down than up

because gravity keeps air pressure away

because air pressure pushes in all directions

because the Earth has an opposing force of gravity

Why is it hard to breath at high altitudes?

There is too much oxygen in this location.

There is a higher density of air molecules.

There is a low density of air molecules.

The air pressure is greater than at low altitudes.

If a hydraulic system has 1000 N applied to the input piston and has an area of 81 cm², what is the pressure?

12.35 Pa

12,346 Pa

1235 Pa

123,457 Pa

11.

An instrument used to measure atmospheric pressure.

barometer

pressure meter

atomizer

thermometer

12.

Pascal states that

Pressure is force per unit area

When velocity is higher, the pressure is lower

When force is applied, the pressure is transmitted equally through the fluid

Pressure transmitted is directly proportional to the force applied

P1 > P2

F1 > F2

P1 = P2
