Question

principle of floatation​

Answer 1

Explanation:

the concept of floating and sinking has many applications .some of them are -

1. the relative density of candle wax is 0.93,hence objects made of wax float on water .
2. unlike the over water , sea water has lots of salts dissolved in it. So,sea water is denser than river water .therefore ,it is easier to swim in sea water than in river water .
3. the density of ice is less than that of water .this is why ,icebergs float on sea water .
4. since river water has a lower density than seawater , a ship loaded with cargo submerges more in river water than in sea water . So,the weight of the cargo has to be limited to prevent the sinking of a ship in river water. for the same reason , all ships have markings on their hall to indicate the level up to which they can be submerged safely in a particular sea or river .these markings are called plimsoll line . if a ship is loaded beyond its plimsoll line , it runs the risk of sinking ....hope it helps u ....
