Question

a small, jagged particle with a density of 1.2 g/cm³ deposits on the ground before a large, round particle with a density of 0.82 g/cm³. which most likely influences the rate of deposition of the jagged particle? large size low density high density irregular shape

Explanation:

When comparing the two particles, the small jagged particle has a higher density ($1.2\ g/cm^{3}$) than the large round particle ($0.82\ g/cm^{3}$). Density plays a significant role in sedimentation (deposition). Higher - density particles tend to settle (deposit) more quickly. The size of the jagged particle is smaller than the round particle, so size is not the factor here. The density of the jagged particle is high, not low. While shape can affect deposition (more jagged particles may have more frictional resistance), in this case, when comparing to a particle with a lower density, the density difference is more likely the dominant factor.

Answer:

high density
