A scuba tank, when fully submerged, displaces 14.0 L of seawater. The tank itself has a mass of 12.8 kg and, when "full," contains 3.30 kg of air.

a).Assuming only a weight and buoyant force act, determine the net force (magnitude) on the fully submerged tank at the beginning of a dive (when it is full of air). Ffull=?

b). Assuming only a weight and buoyant force act, determine the net force (magnitude on the fully submerged tank at the end of a dive (when it no longer contains any air). Fempty=?
