A cubic object of dimensions L = 0.608 m on a side and weight W = 4450 N in a vacuum is suspended by a wire in an open tank of liquid of density p = 944 kg/m³, as in Fig. 15-19. (a) Find the total downward force exerted by the liquid and the atmosphere on the top of the object. (b) Find the total upward force on the bottom of the object. (c) Find the tension in the wire. (d) Calculate the buoyant force on the object using Archimedes' principle. What relation exists among all these quantities?

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of spring
constant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by the
damping constant b = 0.07kg/s.
(i) Find the period of the damped oscillation.
(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
