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%.

Draw a free body diagram to help you visualize. draw the object and use arrows to label and determine where all the forces acting upon it will be. then u add up the sum of all forces. if two forces of equal magnitude and opposite directions will cancel each other out.
Answer:
The correct answer is "
".
Explanation:
According to the question,
The work will be:
⇒ 
Thus the above is the correct answer.
The rate of energy radiated by the man is 3.86 x 
J/s. 
.
The amount of energy radiated by an object majorly depends on the area of its surface and its temperature. The is well explained in the Stefan-Boltzmann's law which states that:
Q(t) = Aeσ
where: Q is the quantity of heat radiated, A is the surface area of the object, e is the emmisivity of the object, σ is the Stefan-Boltzmann constant and T is the temperature of the object.
To determine the rate of energy radiated by the man in the given question;
= Aeσ
But A = 1.7 m², e = 0.4 and σ = 5.67 x J/s.
So that;
= 1.7 * 0.4 * 5.67 x
= 3.8556 x
= 3.86 x J/s.
Thus, the rate of energy radiated by the man is 3.86 x J/s. .
