Iceberg area: 3.10x10^4 km^2, Flat top and bottom.
Submerged part .84 km.
Water density: 1.035x10^3
what is the buoyant force acting on the iceberg?
Homework Equations
Fb=Fg pf object of subject = P0V0g
PfVfg=Weight of displaced fluid=p0v0g=weight of object
Vu=v0-vf=v0-(p0v0g/pfg)=v0(1-(po/pf)
I have spend now over 2 hours trying to solve this problem, but no success... Can any help me solve it... driving me crazy..
Thanks in advance..
Buoyant force is the upward force exerted by a fluid (such as water) on an object that is partially or fully submerged in the fluid. It is caused by the difference in pressure between the top and bottom of the object.
Buoyant force is calculated by multiplying the density of the fluid by the volume of the displaced fluid and the acceleration due to gravity. The formula is Fb = ρVg, where Fb is buoyant force, ρ is the density of the fluid, V is the volume of the displaced fluid, and g is the acceleration due to gravity.
The buoyant force on an object is affected by the density of the fluid, the volume of the displaced fluid, and the acceleration due to gravity. It is also affected by the shape and size of the object, as well as the depth at which it is submerged.
Buoyant force is directly related to Archimedes' Principle, which states that the buoyant force on an object is equal to the weight of the fluid it displaces. This principle helps explain why objects float or sink in fluids.
An example of a buoyant force problem could be calculating the buoyant force on a boat that is floating in a lake. This would involve using the formula Fb = ρVg and considering the density of the water, the volume of the boat, and the acceleration due to gravity.
