- 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 46.0 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 bone: m3 What is its average density? average density of the bone: kg/m³ about us privacy policy terms of use contact us help careersA hollow plastic sphere is held below the surface of a lake by a cord anchored to the bottom of the lake. The sphere has a volume of 0.650 m3 and the tension in the rope is 900 N. (a) Calculate the force of pushing water on the sphere. (b) What is the mass of the sphere? (c) The cord breaks and the sphere rises to the surface. When the sphere stops, what fraction of its volume will be submerged?a diving sphere has a mass of 2.05x10^5 kg and an external diameter of 12.0 meters. the sphere initially floats on the surface of the ocean. the density of the sea water is 1025 kg/m^3. a large anchor is then attached to the sphere and it sinks to the ocean floor at a depth of 1.49 km. what is the buoyant force felt by the submerged sphere? what is the tension in the anchor cable?
- A cube, 0.8 cm on a side, and a mass of 100 g is completely submerged under water (pwater = 1.0 g/cm3= 1000 kg/m3 ) and released. a) What is the density of the cube in g/cm3? b) Draw a free-body diagram for the cube. c) What is the buoyancy force on the cube? d) What is the acceleration of the block after being released under water? (include direction of acceleration in your answer)You need to determine the density of a ceramic statue. If you suspend it from a spring scale, the scale reads 28.4 N. If you then lower the statue into a tub of water so that it is completely submerged, the scale reads 17.0 N. What is the density?A scale reads 100 N when a piece of aluminum is hanging from it. What does it read when it is lowered so that the aluminum is submerged in water? The mass density of aluminum is 2700 kg/m^3. Be careful, you are given mass density instead of weight density, and we are using SI units.i need answer in problem sigfig
