Later, the boat is submerged until it takes … Buoyancy , or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. The pressure difference results in a net upward force on th… WebGeneral paleness affects the entire body. It is most easily seen on the face, lining of the eyes, inner mouth, and nails.
