Pressure

What is the correct equation to calculate pressure?

• none

pressure can be defined as

• force per cubic meter

• force exerted by a fluid on a solid

• force exerted per unit area

• product of force and area

Pa is the SI unit for which quantity?

• mass

• force

• area

• pressure

Complete the statement:

The larger the area, then ___________.

• the larger the pressure

• the smaller the pressure

• the pressure will equal the force

• none

CALCULATE THE PRESSURE:

A box on the floor has a weight of 200N. The surface area the box takes up is 4m².

What is the pressure exerted by the box?

•  50 Pa

• 800 Pa

• 0,02 Pa

True / False:

Pressure can be transmitted through a liquid.

Look at the picture. Select the correct statement.

• In Picture A, the pressure is small because the force is larger than the area.

• In both pictures the pressure is the same

• In Picture B, the pressure is large due to a small area of the needle

• In Picture A, the force and area are equal.
