A spherical submarine, with radius 4 m, has mass such that it is neutrally buoyant; i. its average density is equal to the density of the surrounding water. It now wants t move toward the bottom of the sea at a constant velocity - 0.3 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)

A small solid ball is released from rest while fully submerged in a liquid and then its kinetic energy is measured when it has moved 4.10 cm in the liquid (if it moves). The figure gives the results after many liquids are used: The kinetic energy K is plotted versus the liquid density plig, and Kg = 1.70 J sets the scale on the vertical axis. What is the volume of the ball in m3? K, 1 3. Pliq (g/cm³) K (J)
A cube of side L whose density is 2 g/cm3 floats submerged up to its half in a liquid density 4 g/cm3 as sample Figure 1.
