A solid aluminum ingot weighs 89N in air. a. What is its volume? (The density of Al is 2.7x103kg/m3 ) b. The ingot is suspended from a rope and totally immersed in water, what is the buoyant force? And c. What is the tension in the rope (apparent weight of ingot in water)?

8. A piece of copper has a mass of 2.6 kg. a. What is the volume of this piece of copper?b. The copper is then totally submerged in water. What is the buoyant force acting on it? c. What is the piece of copper’s apparent weight in the water?

5. You are designing a diving bell to withstand the pressure of seawater at a depth of 250 m. a. What is the gauge pressure at that depth? b. What is the net force due to the water outside and the air inside the bell on a circular glass window 30.0 cm in diameter if there is 1.00 atm of pressure inside the bell.

An incompressible box is completely submerged in water at a depth of 60m. The volume of the box is 8L and it has a mass of 30 kg. The buoyant force on the box is  70N.. If the box is brought to a depth of 90m, stae what the mass of the box ,volume of the box and buoyant force on the box will be? Choose one correct answer with the correct units of measure.   A. Mass = 70kg Volume  = 8L Buoyant force = 30N   B. Mass = 30kg Volume = 8 m3 Bouyant force = 70 pound   C. Mass = 30kg  volume = 8L Buoyant force  =70N   D. Mass = 8 kg Volume = 30L Buoyant force  = 70N

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)

A common way of salvaging cannons from old wrecks is to attach an inflatable balloon filed with air.  Assume that the cannon is a solid cylinder of iron which is 1.30m long with a radius 17.3cm.  The density of iron is 7.87g/cm^3. If an air bag were filled twice the volume necessary.   a. What volume of air bag wil be floating above the water surface?

A scientist is calculating the density of an ore sample. The scien- tist measures that the ore sample weighs 22.4 N in air. When the sample is suspended by a thin light cord and totally immersed in water, the tension in the cord is 14.2 N. What is the density of the ore sample that the scientist calculates. You can assume that any buoyant force from air is negligible.

Hi please help: A cylindrical container with a cross-sectional area of 69.2 cm^2 holds a fluid of density 856kg/m^3. At the bottom of the container the pressure is 128kPa. Assume Pat= 101kPa A. What is the depth of the fluid? B. Find the pressure at the bottom of the container after an additional 2.25x10^-3m^3 of this fluid is added to the container. Assume that no fluid spills out of the container

An object of volume 2.00 m^3 is fully submerged in water ( ?water=1000.00 kg/m^3 ). In order to keep the object stationary, an upward force of 7600.00N must be applied to keep the object from sinking. Determine the density of the object. a. 612.24 kg/ m^3 b. 19600.00 kg /m^3 c. 387.76 kg /m^3 d. 12000.00 kg/ m^3 e. 1387.76 kg/ m^3
