mpletely submerged. The container is 5.9 m long, 2.8 m wide, and 2.3 m high. Salvage experts attach a spherical balloon to the top of the container and inflate it with air pumped down from the surface. When the balloon's radius is 1.7 m, the shipping container just begins to rise towards the surface. What is the mass of the container? Ignore the mass of the balloon and the air within it. Do not neglect the buoyant force exerted on the shipping container by the water. The density of seawater

OSU has been given a large model of the solar system which consists of hollow Styrofoam spheres of different sizes representing the Sun and planets. The planets are all connected to the center of the sun by means of steel rods of varying lengths and at varying angles relative to the x-axis as shown above. The steel rods are all 0.5 cm in diameter and are made of steel having a density of 7.88 g/cm3. We’d like to suspend the model from it’s center of mass, but it doesn’t look like the center of mass coincides with the position of the Sun. Find the center of mass of the model (direction and angle) relative to the Sun in the center of the model. The Styrofoam spheres are so much lighter in comparison to the rods, that their mass can be neglected. Hint: calculate the center of mass for the x and y dimensions separately, then combine them to get the final answer

A large spherical air balloon is filled with helium. If the balloon is to support (meaning produce a net acceleration of 0) a total load of 300 kg, including its own mass, calculate the minimum radius of the balloon. Assume values of the density of air and helium to be 1.29 kg/m and 0.18 kg/m respectively 4.8 m 3.6 m O 3.8 m O 3.1 m O 4.5 m

Suppose that a solid cube of some material floats motionless on the surface of an oil puddle at a service station with  61.5%  of its volume submerged. The density of the oil is  907 kg/m3. What is the density  ?  of the cube's material?     1000  kg/m3     558  kg/m3     796  kg/m3     145  kg/m3
