The fraction of the iceberg that is above the surface of the water is 8.3 %.
The specific gravity of any material is defined as the ratio of the density of the material to the density of water.
Mathematically, the formula for specific gravity of materials =
= S.G = density of the material / density of water
Specific gravity of the iceberg = 0.917
Specific gravity of the seawater = 1.025
The fraction of the iceberg submerged in the seawater =
= 0.917 = 0.917 x 100 %
= 91.7 %
The fraction of the iceberg that is above the surface of the water =
= 1 - 0.917
= 0.083
= 0.083 x 100 %
= 8.3 %
Thus, the fraction of the iceberg submerged in the water is a function of the specific gravity of the iceberg.
