Question

1) State Archimedes principle?

2) Give two applications of archimedes principle.

Answer 1

when an object is fully or partially immersed in liquid it experience a buoyant force or upthrust which is equal to the weight of liquid displaced by the object.
application:
*desigie ship and submarine's
*determining the relative density of substance

Answer 2

when an object is wholly or pertially submerged under water it experience an upthrust which is equal to the water displaced due to this upthrust
two app are
1... determing the purity of an sample of milk using lactometer
2... determination of density of liquids using hydrometer
