To Find: The fraction of an iceberg is above the surface of the water
Answer to Problem 33P
The fraction of iceberg above the water surface is
Explanation of Solution
Given information:
For ice,
For sea water,
Density of water,
Formula used:
- When an object is submerged into the fluid, then a force is provided by the fluid to the object, this force is known as Buoyant force.
- Specific gravity is the density of the substance divided by the water’s density, so,
This force is written as,
Calculation:
Now, substitute the given values in the above formula for calculating the density for ice and sea water.
And,
The net force is
Now, the buoyant force for iceberg is
From the above two equation,
Now, percentage of iceberg above water
But,
So,
Conclusion:
The fraction of iceberg above the water surface is
