^{-3}

- 0.015kgm
- The thickness of a molecule is 0.000000001m. This can be written as
- 1.0x10
^{9}m - 1.0x10
^{-9}m - 1.0x10
^{10}m - 1.0x10

- A spherical stone has a mass of 1546kg and if its radius is 2.0cm. Find the density of the stone in gm
^{-3}- 4.6848kgm
^{3} - 0.046848kgm
^{3} - 46.848kgm
^{3} - 0.00004648kgm
^{3}

- 4.6848kgm
- Density can be calculated from
- Mass/Volume
- Mass x Volume
- Volume/Mass
- area x height

- A stone of density 5gcm
^{-3}is dropped in a measuring cylinder containing a liquid. The liquid level rises from 25cm^{3}to 55cm^{3}. Calculate the mass of the liquid displaced by the stone.(Take density of liquid as 1.2gcm^{-3})- 0.36g
- 150g
- 0.15g
- 3.6g

- Fundamental quantities are defined as
- quantities that cannot be expressed in terms of other quantities
- quantities that can be expressed in terms of other quantities
- quantities that can be expressed a percentage of other quantities
- quantities that cannot be expressed as a percentage of other quantities

- The intermolecular forces is strong in solids than liquids. This is becuase;
- they are not fixed in one position in which they vibrate
- they are fixed in one position in which they vibrate
- they are not fixed in one position in which they vibrate
- they are not fixed in one position in which they vibrate

- The displacement method is used to measure the volume of
- nice objects
- regular objects
- irregular objects
- shaped objects

- Surface tension
- Cohesion
- Viscosity

- Three of the fundamental physical quantities are;
- length , time and weight
- volume, temperature, pressure
- Density mass and time
- length, time and mass
