A 3.4kg aluminium ball has an apparent mass of 2.10kg when submerged in a particular liquid. Calculate the density of the liquid.

1083.3kg/m ³

Explanation:

Given parameters:

Mass of aluminium ball = 3.4kg

Apparent mass of ball = 2.1kg

Unknown:

Density of the liquid = ?

Solution:

Density is is the mass per unit volume of any give substance;

         Density =

     Now, we must understand that the apparent weight of the aluminium is the part of its weight supported by the fluid;

   Pl =

   Pl = density of liquid

   Ml = mass of liquid

   Vl = volume of liquid

 Mass of liquid = Mal - Mapparent

       Mal = mass of aluminium

The volume of liquid displaced is the same as the volume of the aluminium according to Archimedes's principle;

              Ml = Pl x Vl

      Val = Vl

      Val volume of aluminium

      Vl = volume of liquid

            ****

        Pal =

       Val =

       Val = volume of aluminium

       Mal = mass of aluminium

       Pal = density of aluminium

   *****

      Since the Val = Vl

          Ml = Pl x

    Since

          Ml = Mal - Mapparent

                Mal - Mapparent  = Pl  x

Pal = density of aluminium = 2712 kg/m ³

             3.4 - 2.1 = Pl x

                 1.3 = Pl x 0.00123

                    Pl = 1083.3kg/m ³

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
