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 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?

A spring is attched to the bottom of an empty swimming pool, with axis ot the spring oriented vertically. An 8.0 kg block of wood with density of d=850 kgm^-3 is fixed to the top of spring and compereeses it. Then the pool is filled with water, completley covering the block. The spring is now observed to be streched twice as much as it had been compressed. a) Determine the percentage of the block's total volume that is hollow. Ignor...

QUESTION 4 a) The human femur bone breaks if compressive stress greater than 1.50 * 10 N/m2 is imposed on it. Assuming the Young's modulus for bone is 1.50 * 1010 N/m2, determine 1) the maximum force that can be exerted on the femur bone in the leg if it has a cross-sectional area of 4.90 x 10-4 m2 by how much does a 0.400 m long bone shorten if this maximum force is applied compressively to the bone. (6...

A diver is located 63 m below the surface of the ocean (the density of seawater is 1.025 kg/m3). To raise a treasure chest that she discovered, the diver inflates a plastic, spherical buoy with her compressed air tanks. The radius of the buoy is inflated to 0.41 m. If the treasure has a mass of 215 kg, what is the acceleration of the buoy and the treasure chest when they are tethered together and released? The chest is 22...
