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;
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%.

Answer:
(A) The magnitude of its angular acceleration 1.09 x 10⁻³ rad/s²
(B) Time of motion 240.2 s
Explanation:
Given;
final angular speed, ωf = 2.5 RPM
angular distance, θ = 5 rev = 5 x 2π = 10π rad
initial angular speed, ωi = 0
final angular speed in rad/s;
(A) the magnitude of its angular acceleration(rad/s^2);
(B) Time of motion;
