3. What is the density of an object that is 27% submerged when floating in water at 0°C? What percentage of the obje...
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...
What fraction of ice is submerged when it floats in freshwater, given the density of water at a temperature of 0°C is very close to 1000 kg/m3 ?
When a block is completely submerged under water, the buoyancy force on it is 11.6N; when it is completely submerged under an unknown liquid, the buoyancy force is measured to be 10.5N. What is the density (in unit of kg/m3) of the unknown liquid?
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 20 kg piece of metal displaces 7.8 L of water when submerged. Find the density (kg/m^3) A 2.3 m-tall barrel is filled with water (with a weight density of 2127N / (m ^ 3) ). Find the water pressure (in kPa) on the bottom of the barrel Find the force of gravity between a object (mass = 2.9 kg) and another planet (mass=7.6*10^ 23 kg) when the planet at its closest to Earth \ d/stance=1.2 x 10^ 10 m)...
A 4.00 cm x 4.00 cm x 4.00 cm cube of density 920 kg/m3 is floating at rest at the top of a beaker of cross sectional area 100 cm2 with 500 mL of water in it. 500 mL of oil of density 900 kg/m3 is added to the top of the beaker, and the cube is observed to float completely submerged, unevenly straddling the boundary between the oil and water. a. Draw a picture showing the beaker, layers of...
