An object with a density of 10.2 g/cm³ will not float in water, as it is denser than water's typical density of 1.0 g/cm³. Option B is correct.
No, an object with a density of 10.2 g/cm³ will not float in water. The key to understanding this concept lies in the principle of buoyancy, which states that an object will float if its density is less than the density of the liquid it is submerged in.
The density of water is typically 1.0 g/cm³, which is equivalent to 1000 kg/m³. Since 10.2 g/cm³ is greater than 1.0 g/cm³, the object in question is denser than water, and therefore, it will sink rather than float.
Hence, B. is the correct option.
