Consider two cubes with side length of 10 cm. The cubes are submerged in water. One cube is made from wood (density of 460 kg/m3) and the other cube is made from aluminium (density of 2742 kg/m3). N J (a) Will the buoyancy force acting on these two cubes be the same or different? Please explain your answer. Ņ (b) Will these cubes float or sink? Please explain your answer. (c) Would the behaviour of the cubes change if they were placed in oil (with density of 894 kg/m3) instead of water?

< The mass of a piece of ice is 0.850 kg. density of water = 1.00 x 103 kg/m³, and density of ice = 917 kg/m³. 2. What is the buoyant force on the ice floating freely in liquid water? Enter a positive answer if the buoyant force is upward and a negative answer if the buoyant force is downward. N Question 2 (of 8)

Please answer A-C

Suppose your body has a density of 988 kg/m3. part a)  What fraction of you will be submerged when floating gently in freshwater (with density 1000 kg/m3)? (hint: vsf/vo) part b)   What fraction of you will be submerged when floating gently in salt water (with a density of 1027 kg/m3)?

Over the summer I decide to supplement my income educational offerings by building a glass-bottomed boat to drive around Lake Michigan. The glass floor is a rectangle, two meter by three meters, and that floor lies one meter below the water's surface. What additional force pushes up on the glass floor due to the increased gauge pressure underwater?  a 10,000 N  b 40,000 N  c 60,000 N  d 120,000N

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.

Part B - An aluminum block of volume 200 × 10-6 m3 is held by a string at rest in oil as shown. ρAL = 2700 kg/m3, ρoil = 900 kg/m3, and g = 10 m/s2.  Now the same block is placed in water, still completely submerged. Water is more dense than oil. The net force on the block will  ______.       Answers: decrease   increase   stay the same   Part C -  Now the same block is placed in water, still completely submerged. Water is more dense than oil. The buoyant force on the block will  ______.       Answers: stay the same   decrease   increase   Part D -  Now the same block is placed in water, still completely submerged. Water is more dense than oil. The tension in the string will  ______.       Answers: stay the same   decrease   increase

What is the buoyant force of an object with a volume of 0.5 m3 that is fully submerged in water? The density of water is 1000 kg/m3. O 500 N O 420 N 4,900 N 9,800 N
