What is the smallest division you can measure to with a metre rule?

• 1 mm
• 1 cm
• 0.5 cm
• 0.5 mm

The SI units for length, mass and time are:

• metre, kilogram, second
• metre, gram, second
• centimetre, gram, second
• far, heavy, long

The reading shown on the micrometer is:

• 6.48 mm
• 6.20 mm
• 6.02 mm
• 5.98 mm

The average of these three measurements:
34.53 s    33.97 s   34.09 s

• 102.59 s
• 34.20 s
• 34.17 s
• 102.5 s

The instrument used to measure volumes of liquid

• measuring cylinder
• measuring cup
• measuring bucket
• measuring beaker

The amount of mass per unit of volume is

• density
• weight
• Newton
• strength

The SI unit for density

• kgm^-3
• kgm³
• kg³m
• kg^-3m

Calculate the density of 891 g of mercury that takes up a volume of 66 cm³

• 13.5 gm^-3
• 58800 gm^-3
• 58.8 gm^-3
• 0.0135 gm^-3

Determine the volume taken up by 1650 g of iron if the density is known to be 7895 kgm^-3

• 209 cm³
• 209 m³
• 0.000209 cm³
• 20.9 m³

If a solid object has a density of 0.925 gcm^-3

• it will float in water
• it will sink in water
• it will float in mid-air
• it will sink at first but then stop halfway down
