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 2.49 × 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...

A spring is attached to the bottom of an empty swimming pool, with the axis of the spring oriented vertically. An 7.55-kg block of wood (density = 715 kg/m3) is fixed to the top of the spring and compresses it. Then the pool is filled with water, completely covering the block. The spring is now observed to be stretched twice as much as it had been compressed. Determine the percentage of the block's total volume that is hollow. Ignore any...

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...
