DBS10012 - SOLID & LIQUID (TOPIC 5)

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

What is the volume of Object X?

• 10.0 cm³

• 15.0 cm³

• 20.0 cm³

• 25.0 cm³

This principle says that an increase in pressure on a confined fluid is transmitted equally to all parts of the fluid.

• Newton's Principle

• Bernoulli's Principle

• Archimedes' Principle

• Pascal's Principle

What direction is the buoyant force in?

• Downward
• Left
• Right
• Upward

What are the three states of matter? 

• boxes, solids, and gases
• square, circle and triangle
• solids, liquids and gases

Gas particles move in random direction and at...

• steady speeds

• random speeds

• faster speeds

• slower speeds

Which state of matter is able change to the shape of the container but not be compressed?

• Solids

• Gases

• Liquids

• Sublimation

What was the principle Archimedes discovered?

• Principle of Volume
• Principle of Density
• Principle of Buoyancy
• Principle of Gravity

If an object weighing 50.0 N displaces a volume of water with a weight of 10.0 N, what is the buoyant force on the object?

• 10 N
• 60 N
• 40 N 
• 20 N 

In a car lift, compressed air exerts a force, F₁ on a small piston having a radius of 5.5 cm. This pressure is transmitted to a second piston of radius 20 cm as shown in figure above. The mass of the car is 1250 kg.

Calculate the pressure on the smaller piston F_1.

• 6.25 kPa

• 61.31 kPa

• 97.57 kPa

• 306.56 kPa
