Question

what does the shape of a particle affect?
o buoyancy
o density
o drag
o volume

Explanation:

The shape of a particle affects the resistance it experiences as it moves through a fluid (drag). Buoyancy depends on the volume of fluid displaced and the density of the fluid and particle, density is mass per unit volume and is an intrinsic property not directly related to shape, and volume is a measure of the space occupied and while shape can influence how volume is calculated, it's not the primary factor affected by shape in the context of fluid - particle interaction. Drag is highly dependent on the shape of the particle as different shapes encounter different levels of fluid resistance.

Answer:

drag
