X represents kerosene and Y represents water Among A and B which is the right figure Why Answer B is the right figure. All you have to do is provide the density of a fluid and the volume of an object that stays underwater and it will use the buoyancy formula to estimate the force that keeps the object floating. where rho is the density of the fluid V is the volume of fluid displaced and g is acceleration due to gravity. Because it s The relative density of one water mass in relation to another determines whether a layer of water floats or sinks. Put dropper in bottle and put on cap 4. There are situations where density is a function of the 2. Pascal 39 s principle explains the relationship between density and buoyancy. However the steel ball has more weight since it has a higher density. For example when a piece of wood is pushed into different fluids different forces have to be applied to do so.

Find the difference between the actual and apparent masses and compare this to the mass of the water displaced using relationship 3 . 3. Develop the relationship between the densities of liquids and solid and the location of the solid cubical. DENSITY amp BUOYANCY Having the same density as water means that the boot s buoyant force is equal to the weight of the boot. This buoyancy centric view however does not directly account for frontal precipitation or stratiform rain Houze 1997 Schumacher and Houze 2003 even though the Density is defined by the ratio of the mass of a substance to its volume. On the other hand buoyancy is the force exerted by the liquid on the object immersed in the liquid and it depends only on th The buoyancy of an object is its tendency to float on or rise in a liquid. However the relationship between density and if the egg floats or sinks is not a direct causality. The reason a large steel carrier can float in the water is due to its density characteristics and the resulting floating properties as expressed in its buoyancy. Other forces act on a floating body in the ocean such as drag due to the density of the fluid thrust if the body pushes the water away and weight which pushes the body down toward the ocean floor . Figure 4. What is weight Click card nbsp Download scientific diagram Figure S2. This article contains a temperature salinity diagram with lines for different buoyancy. P nbsp Density is a measurement of an object 39 s mass per unit volume of space that it occupies.
