A block of mass 0.55 kg and density 2900 kg/m³ is completely submerged under the water in static equilibrium on top of a spring (k = 50.0 N/m) that is fixed to the bottom of the container as shown in the figure. How much is the spring compressed? (The density of water is 1000 kg/m³)

A block of mass 30 kg and volume 0.025 m3 is allowed to sink in water as shown. A circular rod 5 m long and 25 cm2 in cross section is attached to the weight and also to the wall. If the rod mass is 1.25 kg, what will be the angle, θ, for equilibrium?

Two blocks that have the same volume (V) and different masses (m1 = 0.45 kg and m2 = 1.35 kg) are connected by a string and suspended in water (density = 1000 kg/m³) as shown in the figure. If the top block is half submerged: a) Draw a free body diagram for each block. b) Using the static equilibrium condition, derive the algebraic expression for the volume of each block. c) Calculate the volume of each block.
