To verify her suspicion that a rock specimen is hollow, a geologist weighs the specimen in air and in water. She finds that the specimen weighs twice as much in air as it does in water. The density of the solid part of the specimen is 5.87 × 103 kg/m3. What fraction of the specimen’s apparent volume is solid?

To verify her suspicion that a rock specimen is hollow, a geologist weighs the specimen in air and in water. She rinds that the specimen weighs twice as much in air as it does in water. The density of the solid part of the specimen is 5.17 times 10^3 kg/m^3. What fraction of the specimen's apparent volume is solid'

Bird bones have air pockets in them to reduce their weight. This also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 45.0 g and its apparent mass when submerged is 3.60 g(the bone is watertight). What mass of water is displaced? mass of water displaced: kg What is the volume of the bone? volume of the...

LEARN MORE REMARKS Because the density of gold Is 1.93 x 104 kg/m", the crown is elther hollow, made of an alloy, or both. Despite the mathematical complexity, it is certainly conceivable that this was the method that occurred to Archimedes. Conceptually, it's a matter of realizing (or guessing) that equal weights of gold and a silver-gold alloy would have different scale readings when immersed in water because their densities and hence their volumes are different, leading to differing buoyant...

To know how many Helium balloons are needed to lift a girl who weighs 35 kg, one intends to measure how much weight a single balloon can lift. A scale that is sensitive to 0.1 g, small pieces of copper, and an ordinary party balloon show that a balloon with a volume of about 2 l can lift 2g of copper. How many balloons will it take to lift the girl? Does this agree with the result obtained if you...
