Question

The density of of ice is 917 kilogram per metre cube. what fraction of ice lies below water ? The density of seawater is 1024 kilogram per metre cube. what fraction of iceberg do we see assuming that it has the same density as ordinary ice 917 kilogram per metre cube?

Answer 1

Answer:

10.5/100 fraction

Explanation:

formula from laws of floatation=h/H=Density of ice/density of sea water

h is the height of the glacier which is not visble and H is the total height of the glacier including the length underneath.

h/H=0.917/1.024

h/H=0.895

ratio =89.5 % , hence we se only 10.5%

to Make things convenient and to understand round off 0.895 to 0.9 which means

h/H=0.9

h/H=9/10

now this means we cant see almost 90% of the glacier ans what we see is just 10% of it.
