When a wooden box is placed in a pail of water, it floats with 40% of its height above the waterline. When this box is placed in a pail full of oil, it floats with 30% of its height above oil. What is the density of (a) box (b) oil?
A wooden raft has a mass of 100.0 kg. When empty it floats in water (density of 1000 kg/m3 ) with 40% of its volume submerged. How many students of mass 75 kg each can stand on the raft without it sinking?
A wooden disk with density 700 kg/m 3 floats face down in pure water. It has radius 50.0 cm and thickness 20.0 cm. (a) Calculate the height of the top of the disk above the water level. (Answer: 6.0 cm) (b) A lead weight is loaded onto the disk, so that the disk sits deeper in the water, and its top face is now only 2.00 cm above the water level. Calculate the mass of the lead weight. (Answer: 31.4...
A wooden cylinder 30.0 cm high floats vertically in a tub of water. The top of the cylinder is 14.1 cm above the surface of the liquid. What is the density of the wood?
When a large cube is placed in a tub of water, it floats with 0.5 m of it submerged. When the same cube is placed in anunknown liquid, 3.5 m of it is submerged. What is the density of the unknown liquid (in kg/m3)?
A wooden block of volume 5.26 times 10^-4 m^3 floats in water, and a small steel object of mass m is placed on top of the block. When m = 0.400 kg, the system is in equilibrium and the top of the wooden block is at the level of the water. (Take the density of steel to be 8 g/cm^3.) (a) What is the density of the wood? kg/m^3 (b) What happens to the block when the steel object is...
6.) A plastic cube is placed in a cup of pure water and it floats with 28.0 % of its volume above the surface. The same cube is then placed in a cup of an unknown fluid, and it floats with only 16.0 % of its volume above the surface. What is the density of the unknown fluid?
When a 122.4kg chest is placed on the raft, the raft floats with its top surface 20cm above the water(10 cm is under water). The density of the water is 1077 kg/m^3 What is the mass of just the raft? How strong it the buoyant force being exerted by the water on the raft? How many crates can the raft hold (including the on on it)? 30m I poom
A cube is placed in a tub of water and floats with 2.50 m of the cube submerged. An identical cube is placed in a tub of an unknown liquid, and floats with 1.50 m of it submerged. What is the density of the unknown liquid in kg/m3?
Suppose you pour water into a container until it reaches a depth of 20 cm. Next, you carefully pour in a 8.5 cm thickness of olive oil so that it floats on top of the water. What is the pressure at the bottom of the container? Express your answer using two significant figures. Density of olive oil and water not given.
