Compared to a rounded particle with low density, a HIGH density, rounded particle of the same size will sink through water

•more slowly
•at the same rate
•more rapidly

more rapidly

Explanation:

Density of a substance refers to the mass of that substance in relation to one unit of its volume. The density of a substance is the basis of whether such substance will float or sink in a liquid. This means that if the density of an object is higher than that of a liquid medium e.g water, the object will SINK while if the density of the object is lower in relation to the liquid medium, the object will FLOAT.

According to this question involving a rounded particle. If the rounded particle is of low density than water, it will float. However, if the rounded particle of the same size is of HIGH density than water, it will SINK MORE RAPIDLY.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
