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.
How should the student calculate the density of the stone?
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?A
A
B
C
D
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 10g.
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 2.5g/cm3.
What is the mass of the block?
8.0 g
16 g
50 g
100 g

2 000 J
8 000 J
10 000 J
12 000 J

dead plant and animal remains
sedimentary rocks
magma and lava
water
Hydroelectric power is electricity created by
water
the sun
burning coal

One con of hydroelectric power is that dams can
create lakes
control irrigation
block routes for fish
keep soil rich
Which is a CON of solar energy?
energy can be saved in summer to use in winter
it can lower electric costs
there is a lot of sun in the desert
solar panels can be expensive
One pro of nuclear energy
it doesn't create pollution

it increases global warming
One danger of nuclear power plants is that
atomic bombs are not dangerous
the waste material is radioactive
water creates pollution
atoms are difficult to find
What is the unit of electrical power?
