When an object with a volume of 4 x 10^-3 m^3 is completely submerged in water ( p water = 1000 kg/m^3), the buoyant force acting on the object will be?

A metal has mass of 8 kg when the mental is hanging from a spring scale and the totally submerged in water, the scale needs 3.30kg. What is the density of the mental? (water density=1000kg/m^3) (A)2.80x10^3kg/m^3 (B)5.80x10^3kg/m^3 (C)1.70x10^3kg/m^3 (D)3.30x10^3kg/m^3

A cube of some unknown substance sits on the surface of water. The cube has a mass of 0.450 kg and a volume of 0.000720 m^3.How much additional mass can be placed on top of the cube without it sinking? [The entire cube will be stationary, but submerged.]

A large rectangular cube made of wood has the follow dimentions: a height, h = 2m, and an area od A = 0.25m^2. The wood that the cube is made of has a density of 800kg/m^3. The cube is then place vertically in water where it floats to rest. The density of the water is 1000kg/m^3. Then the cube is pushed down slightly (by a distance y) and released. The resulting motion is simple harmonic motion.    A) Determine the mass of the cube. B) Determine the depth,d, that the cube will float. C) If the cube is pushed further down under water by a distance, y, write an expression for the net force on the block in terms of: y,A,g,p. Where g=9.8m/s^2 D)Use the expression for the net forcee found in part C), and apply newton's second law (Fnet = ma) to the situation of the cube that is being pushed down slightly to derive an equation for the vertical accerlation (ay) (hint: dont forget to pick a positive direction)  Compare your results from part D) to the equation for simple harmonic motion using…
