Answer 1

Hi friend, Here is the required answer :-

ARCHIMEDES PRINCIPLE
======================

Archimedes principle states that when a body is immersed fully or partially in a fluid, it experiences an upward force which is equal to the weight of the fluid displaced by it.

APPLICATIONS
==============

The two applications of this principle are:-

1. It is used in designing ships and submarines.

2. Lactometers which are used to determine the purity of milk and hydrometer used for determining the density of liquids are based on this principle.
=========================

Hope this helps you...
PLEASE MARK AS BRAINLIEST ANSWER!!!

Answer 2

★ Archimedes principle ★

states that the upward buoyant force that is exerted on a body immersed in a fluid whether fully, or partially submerged is equal to the weight of the fluid that the body displaces.

some real life practical applications of Archimedes principle is :-

★ used in designing ships , boats and submarines.

★ used in making lactometers, which are used to determine the purity of milk.

★ hydrometer is used for determining the density of any liquid.

★ aquatic animals like :- fishes uses this principle.
