PHYSICS LEVEL 10 UNIT 1 TEST PG

The diagram shows an enlarged drawing of the end of a metre rule. It is being used to measure

the length of a small feather.

What is the length of the feather?

• 19 mm

• 29 mm

• 19 cm

• 29 cm

A student wishes to find the volume of a small, irregularly-shaped stone.

A ruler and a measuring cylinder containing some water are available.

Which apparatus is needed?

• neither the ruler nor the measuring cylinder

• the measuring cylinder only

• the ruler and the measuring cylinder

• the ruler only

A measuring cylinder is used to measure the volume of a quantity of water.

Which measuring technique would not improve the accuracy of the measurement?

• making sure that the measuring cylinder is vertical

• making sure that the water surface is at eye level

• reading the top of the water meniscus

• using the smallest measuring cylinder available that will contain all the water

The diagram shows four identical spheres placed between two wooden blocks on a ruler.

What is the diameter of one sphere?

• 1.0 cm

• 2.0 cm

• 3.0 cm

• 4.0 cm

A student wishes to determine the density of an irregularly-shaped stone.

First he finds the mass of the stone. Next he lowers the stone into a measuring cylinder containing water.

The diagrams show the measuring cylinder before and after the stone is lowered into it.

• mass of stone × reading 2

• mass of stone × (reading 2 – reading 1)

• mass of stone ÷ reading 2

• mass of stone ÷ (reading 2 – reading 1)

The diagrams show the dimensions and masses of four regular solid objects. The objects are made from different metals.

Which metal has the greatest density?

• 
• 
• 
• 

Diagram 1 shows a measuring cylinder containing water.

Diagram 2 shows the same measuring cylinder and water after 10 identical solid glass spheres have been added.
The mass of one of the spheres is 10 g.

What is the density of the glass from which the spheres are made?

• 0.25 g / cm³

• 0.40 g / cm³

• 2.5 g / cm³

• 4.0 g / cm³

The diagram shows a cuboid block made from a metal of density 2.5 g / cm³.

What is the mass of the block?

• 8.0 g

• 16 g

• 50 g

• 100 g

The diagram shows an experiment to find the density of a liquid.

What is the density of the liquid?

• 0.5 g / cm³

• 2.0 g / cm³

• 8.0 g / cm³

• 10.0 g / cm³

Two cylinders are made of the same metal. Both cylinders have the same cross-sectional area but one is longer than the other.

Which quantity is the same for both cylinders?

• density

• mass

• resistance

• volume
