A solid object has a mass of 0.5 kg and a volume of 100 cm^3. If the object is submerged in water, what is the buoyant force acting on the object? (Assume the density of water is 1000 kg/m^3 and g = 9.8 m/s^2.)

A string holds a 100-kg Iron sphere 2 meters below the surface of the Ocean. If the volume of water displaced by the sphere is 0.05 m3, what is the tension in the string? The density of saltwater is 1025 kg/m3. (Hint: Make a force diagram of the string and sphere)

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 wood having an edge dimension of 18.7 cm and a density of 651 kg/m° floats on water. (a) What is the distance from the horizontal top surface of the cube to the water level? cm (b) What mass of lead should be placed on the cube so that the top of the cube will be just level with the water surface? kg

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…

A life preserver is manufactured to support a 70 kg person with 25% of his volume out of the water.   If the density of the life preserver is 100 kg/m^3 and it is completely submerged, what must its volume be? Assume that the density of the person to be about the same as the density of water, 1000 kg/m^3. Express your answer with the appropriate units.

Water has a mass density of 1000 kg/m3. If a block of volume 20 m3 is fully submerged in water, what is the buoyant force acting on it?

If the human body has an average density of 971 kg/m3, what fraction of a person is submerged when floating gently in fresh water?

A 6.2 m^3 object floats in water with 46% of its volume above the waterline. What is the force the Earth exerts on the object? The density of water is 1000 kg/m^3.
