The specific gravity of an material is defined as the ratio of the density of the material to the density of water. The specific
Alexandra [31]

The percentage of the iceberg that is visible above the water's surface will be 11.5%.

<h3>What is density?</h3>

Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.

The mass and density relation is given as

mass = density × volume

Density of ice = 917 kg/m³

Density of the seawater=1025 kg/m³

The ratio by which the iceberg submerge is found as;

\rm  \frac{V_S}{V} =\frac{\rho}{\rho_0} \\\\ \frac{V_S}{V} =\frac{917}{1025} \\\\ \frac{V_S}{V} =.895

Hence,89.5 % of the ice is submerged.

The percentage of the iceberg that is visible above the water's surface is;

⇒1-.89.5 %

⇒11.55 %

Hence, the percentage of the iceberg that is visible above the water's surface will be 11.5%.

To learn more about the density refers to the link;
