(17%) Problem 5: A cube with edge length L = 0.28 m and density Qc = 3.7x105 kg/m3 is exactly half submerged in a liquid of density 91 = 0.87x105 kg/m', as shown in the figure. The cube is suspended by a taut string and is in static equilibrium. L/2 13% Part (a) Which of the following figures shows the correct free-body diagram for the cube for the vertical forces acting on it? T F . Correct! 13% Part (b) Enter an expression for the magnitude of the weight of the cube, in terms of Oc, L, and the acceleration due to gravity, g. w = Qc L' g Correct! 13% Part (c) Calculate the magnitude of the weight of the cube, in newtons. W = 795.9 Correct! *13% Part (d) Enter an expression for the magnitude of the buoyant force acting on the cube, in terms of 91, L, and g.
