A person sinks in a water body while a fish does not because the person has a higher density than the water, the fish displaces less water and also it has less volume, and it has a lesser density than the water.
A fish stays immobile at the same depth in a body of water. A person sinks in the same body of water while not moving. The idea has to do with mass, density, and volume. As a result of having a higher mass and volume than water, a person has a higher density than a fish because the latter displaces less water than the former. A person also has a higher mass than a fish. Therefore, option A, B, D, and E are correct. The mass per unit volume formula is used to compute density. It is described as the total mass that a body contains in relation to its volume. It can be represented as:
Density = mass/volume
This is consistent with the fact that fish have streamlined bodies in addition to their bodies not having any. Human bodies are not streamlined. In addition to its air bladder, a fish has gills that allow it to breathe underwater. This allows fish to survive.
