A homogeneous solid object floats on water with 80% of its volume below the surface. The same object when placed in a second liquid floats on that liquid with 73% of its volume below the surface. Determine the density of the object.
An object of mass M floats with 1/2 its volume submerged in a fluid (fluid A) of unknown density. An identical object of mass M is then placed in a 2nd unknown fluid (fluid B) where it floats with 2/3 of the objects volume submerged. what is the ratio of densities of the fluid A to fluid B?
Two objects of different shapes, sizes, and materials, are floating in water (density 1000 kg/m3). Object A floats with 60% of its volume submerged, while object B floats with 50% of its volume submerged. What can be concluded about the densities ρA and ρB of the two objects? A.) ρA < ρB B.) ρA > ρB C.) ρA = ρB D.) Not enough information
3. Archimedes' Principle states that the buoyant force on an object partially or fully submerged in a fluid is equal to the weight of the fluid that the object displaces. For an object of density po floating partly submerged in a fluid of density pf, the buoyant force is given by F P19 SA(y)dy, where g is the acceleration due to gravity and A(y) is the area of a typical cross-section of the object. The weight of the object is...
3. What is the density of an object that is 27% submerged when floating in water at 0°C? What percentage of the object will be submerged if it is placed in ethanol at 0° C? Density (kg/m3) Liquid Gasoline 680 Ethanol 790 Oil 850 Water (0°C) 999.87 Water (3.98°C) 1000.00 Seawater 1025
4) A) A 10 kg cube of lucite (plastic, get the density from the web) floats on water in a tub. Assume that the tub is large enough for the lucite (so that it is far from the edges and the bottom) what percentage of lucite's volume is below the surface of water. Explain all your calculations, no points for just a numerical answer. (13 pts)
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?
need it asap pls
10. An object will float at the surface of a liquid if the mass of the object is less than the mass of the liquid that it displaces. A spherical vessel (diameter = 2.00 cm) when empty has a mass of 2.00 g. What is the greatest volume of water that can be placed in the vessel and still have the vessel float at the surface of water? (Given: density of water - 1.00 g/cm)
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?
Can you use Archimedes' principle to find the density of an object that floats? a. Yes, attach a weight to the object and find the difference in buoyant forces. b. No, the object must be able to sink. c. Yes, a floating object will still displace fluid equivalent to the buoyant force.
