A spherical submarine, with radius 3 m, has mass such that it is neutrally buoyant; I.e. its average density is equal to the density of the surrounding water. It now wants to move toward the bottom of the sea at a constant velocity = 0.6 m/s. How much extra mass does the submarine need to take in? (It will do this by taking in water, adding to the submarine's total mass) %3D O 0.0046 kg O0.0029 kg 0.0061 kg O 0.0023 kg 0.0035 kg O 0.0039 kg
