Exercises of Archimedes Principle.

 1.   a)    The maximum buoyant force experienced by the boat is 17400N.

       b)      The one who is more eligible to go in the boat is the man  with 60 kg. Because 

           the man will not make the boat inverted.



                                                                       

2.    a)   Hydrometer is used to measure the density of a liquid.

       b)  A lead shoot is place at its bottom so that it can float upright.

       c)  A solid suspended in a fluid will be buoyed up by a force equal to the weight of the fluid displaced by the submerged part of the suspended solid. Thus, the lower the density of the substance, the farther the hydrometer will sink
