일반물리학 1 — Fluids: Problem 44

44 In Fig. 14-39a, a rectangular block is gradually pushed face-down into a liquid. The block has height \(d\); on the bottom and top the face area is \(A = 8.00 \text{ cm}^2\). Figure 14-39b gives the apparent weight \(W_{\text{app}}\) of the block as a function of the depth \(h\) of its lower face. The scale on the vertical axis is set by \(W_s = 0.20 \text{ N}\). What is the density of the liquid?
