What causes buoyant force (or upthrust) on a boat ?

In Fig. , a rectangular block floats in a liquid . A block of mass m = 0.500 kg and density rho = 700 kg//m^(3) floats face down in a liquid of density rho_(f) = 1200 kg//m^(3) . What are the magnitude of the buoyant force on the block from the liquid , the weight of the liquid displaced by the block (liquid that would be in the space now occupied by the block ) , and the mass of that displaced liquid ? What fraction of the block's volume is submerged ? What fraction of its height is submerged ?

According to Archimedes's principle the loss in of weight is equal to (V is the volume displaced by the body, rho is the density of liquid in which body is immersed)

A penguin floats first in a fluid of density rho_(0) then in a fluid of density 0.95 rho_(0) and then in a fluid of density 1.1 rho_(0) . (a) Rank the densities according to the magnitude of the buoyant force on the penguin , greatest first . (b) Rank the densities according to the amount of fluid displaced by the penguin , greatest first.

An object with uniform density ρ is attached to a spring that is known to stretch linearly with applied force as shown below. When the spring-object system is immersed in a liquid of density rho_(1) as shown in the figure, the spring stretches by an amount x_(1)(rho gt rho_(1)) . When the experiment is repeated in a liquid of density rho_(2) gt rho_(1) , the spring stretches by an amount x_(2) . Neglecting any buoyant force on the spring, the density of the object is

The time period (t) of vibration of a liquid drop depends on surface tension (s),radius ( r) of the drop and density (rho) of the liquid .Find t.

Derive an expression for the buoyant force acting on a body completely submerged in a liquid of density rho .

If the time period (T) of vibration of a liquid drop depends on surface tension (S) , radius ( r ) of the drop , and density ( rho ) of the liquid , then find the expression of T .
