A lost shipping container is found resting on the ocean floor and completely submerged. The container is 6.4 m long, 2.4 m wide, and 2.5 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...

3. Archimedes' Principle states that the buoyant force on an object partially or fully submerged in a fluid is equal to the weight of the fluid that the object displaces. For an object of density po floating partly submerged in a fluid of density pf, the buoyant force is given by F P19 SA(y)dy, where g is the acceleration due to gravity and A(y) is the area of a typical cross-section of the object. The weight of the object is...

b. When an object is submersed in a fluid, its weight is reduced due to the buoyant force. Deter- mine the mathematical expression of the apparent weight of an object in terms of the following variables: V,-Volume of the object ρ,-Density of the object Pf Density of the fluid g Gravitational acceleration boyant Cp.

An object completely submerged in an incompressible fluid is at rest. Which of the following are true? (Select all that apply.) If the object is pushed slightly upwards it will slow down until it comes to rest If the object is pushed slightly downwards it will keep moving downwards with constant velocity The mean density of the object is the same as that of the fluid If the object is pushed slightly upwards it will keep moving upwards with constant...

Question 2. Deep sea drones are used to explore the bottom of the ocean. The drone is allowed to sink using its weight force, however if the drone hits the ocean floor with a high velocity the operational camera will break. Hence the velocity of the sinking drone should be less than 4 m/s when hitting the ocean floor. The weight force is countered by drag and buoyancy (See Figure 1). Drag is directly proportional to velocity i.e. D =...
