Question

which is a way to increase an objects buoyancy? increase acceleration increase gravity decrease density

Explanation:

Buoyancy is related to density. According to Archimedes' principle, buoyant force \(F_b=
ho Vg\) (where \(
ho\) is the density of the fluid, \(V\) is the volume of the displaced fluid, and \(g\) is the acceleration due to gravity). For an object, if its density is decreased (while keeping other factors like volume in mind), it can displace more fluid (or in a more general sense, be more buoyant as it is less likely to sink). Increasing acceleration or gravity doesn't directly relate to increasing an object's inherent buoyancy in the way density does.

Answer:

decrease density
