Question

Quizplus · Accepted Answer

Density is defined as the mass per unit volume. A submerged submarine displaces an amount of water equal to its own volume, therefore, if its density is the same as that of water, it will neither sink nor float. Options A and B have densities greater than that of water and would sink, while option C has a lower density and would float.
