Explain the following:
Icebergs floating in the sea are very dangerous for ships.

Solution
Relative density of Ice is = 0.9 cm-3
Relative density of sea water is = 1 cm-3
(Density of ice / Density of sea water) = fraction submerged of iceberg
0.9/1 = fraction of iceberg submerged
The fraction of the iceberg submerged = 9/10.
Thus in colder countries where there are icebergs in oceans, only about 1/10 is seen above water and the remaining water 9/10 remains submerged. Hence, there is a danger of these icebergs to the ships sailing in these oceans.
