Deep water research is conducted from a spherical vessel with a radius and mass respectively of 1.49 m and 1.19 x 104 kg. To dive, the vessel takes on mass in the form of sea water. Determine the amount of mass (in kg) that the vessel must take on if it is to descend at a constant speed, when the resistive force on it is 1,095 N in the upward direction. The density of seawater is 1.03 x 10 kg/m.
