A hollow tube, sealed at one end, has a cross-sectional area A of 24 cm². The tube contains sand so that the total mass M of the tube and sand is 0.23 kg. The tube floats upright in a liquid of density ρ, as illustrated in Fig. 3.1. [Figure 3.1] The depth of the bottom of the tube below the liquid surface is h. The tube is displaced vertically and then released. The variation with time t of the depth h is shown in Fig. 3.2. [Figure 3.2]
