The specific gravity of an material is defined as the ratio of the density of the material to the density of water. The specific

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%.

Explain why energy from the sun cannot reach us by conduction or convection?
34kurt

Answer:

It cannot reach us by conduction or convection as there is no medium such as air in most part of the space between the earth and the sun. From the sun the heat comes to us by another process known as radiation. The transfer of heat by radiation does not require any medium.
