hich of the following statements concerning center of mass and center of buoyancy are correct? Choose all that apply. a. The center of mass and the center of buoyancy for an object can be the same point on the object, given the right conditions. b. An object which sinks to the bottom of a fluid (does not float) still has a center of buoyancy. c. The center of buoyancy of an object never changes no matter how an object is situated in a fluid. d. The center of mass of an object never changes no matter how an object is situated in a fluid. e. If the center of buoyancy and mass are not vertically alligned for a floating object, then that object is inherently unstable. f. For a ship to be stable, the center of mass must always be below the center of buoyancy. g. The metacentric height (M) of a ship must be negative in order for the ship to be stable. h. A neutrally stable object will always have centers of buoyancy and mass which are coincident with each other.
