- You come across an open container that is filled with two liquids. Since the two liquids have different densities, there is a distinct separation between them. Water, which has a density of ?w=1.00×103 kg/m3, fills the lower portion of the container to a depth of 0.215 m. The fluid that is floating on top of the water is 0.307 m deep. If the absolute pressure on the bottom of the container is 1.049×105 Pa, what is the density, ?l, of the unknown fluid? The acceleration due to gravity is ?=9.81 m/s2 and atmospheric pressure is ?0=1.013×105 Pa.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?You come across an open container that is filled with two liquids. Since the two liquids have different densities, there is a distinct separation between them. Water, which has a density of ?w=1.00×103 kg/m3, fills the lower portion of the container to a depth of 0.200 m. The fluid that is floating on top of the water is 0.307 m deep.

- An object with a mass 1kg, when placed in water, has an apparent weight of 5N. It is then placed into a fluid with an unknown density p. Its apparent weight in the unknown fluid is 6.2N. What is the density of the unknown fluid?You put a marble on a balance and find it has a mass of 1.2 grams. It is an irregular shape, so you need to do displacement to find its volume. You put it in a graduated cylinder with a starting volume of 30.0 mL of water. After you add the marble, the water rises to 31.5 mL. What is the density? Group of answer choices 0.038 g/mL 1.3 g/mL 0.80 g/mL 1.8 g/mLA 6.2 m^3 object floats in water with 46% of its volume above the waterline. What is the force the Earth exerts on the object? The density of water is 1000 kg/m^3.
