How will a metallic object possessing a specific gravity of o behave when submerged in a liquid of identical specific gravity a___________________?
Show answer Hide answer
Answer: D. be fully immersed with top surface at fluid surface
Explanation
An object with a specific gravity equal to the fluid remains neutrally buoyant. Equal specific gravities mean the object's density matches the surrounding fluid perfectly. The object is fully immersed with its top surface aligned with the fluid surface. Specific gravity is the dimensionless ratio of an object's density to reference water density. Archimedes principle governs the equilibrium forces acting on submerged and floating bodies. Neutral buoyancy occurs when gravitational downward force equals upward buoyant force.
Submarines adjust ballast tanks to achieve neutral buoyancy at various underwater depths. Hydrometers rely on specific gravity principles to measure liquid densities in laboratories. Marine architects calculate specific gravity to ensure safe vessel loading and flotation. An object sinks to the bottom only if its specific gravity exceeds the fluid density. An object floats over the fluid if its specific gravity is lower than the fluid. Partial immersion occurs when the object's density is less than the surrounding fluid.

Q6. A metal object with a specific gravity of 7 floats atop liquid mercury (specific gravity 13.6). What proportion of its total volume remains submerged beneath the mercury?
Show answer Hide answer
Answer: C. 0.515
The submerged proportion equals the object specific gravity divided by fluid gravity. Dividing 7 by 13.6 yields approximately 0.515. Therefore, 51.5 percent of the metal object volume remains submerged. Specific gravity...
