In all of the cases objects are partially submerged so weight of object will be equal to buyont force and density of water is 1 g/cm3
A. Greatest to lowest
F - B - C - A - E - D
Now for the case F ......
VOLUME of water displaced is 60 cm3
Percentage of volume submerged will be 60/75 *100 which is 80percent
Percentage of volume above the surface 15/75 *100 which is 20 percent
Density of mass to water will be 60/75:1
Which is 4:5

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...

2. 95% of a wood block is submerged in water (density= 1000 kg/m). A layer of oil with a density of 880 kg/m' is now poured on top, to a depth that more than covers the block, as shown. Find the resulting new volume fraction submerged in water, V(in water) / V(block). Hints: (i) You get two buoyant forces - one for each liquid; Also note that (ii) volume, V(block) = V(in water) + V(in oil). d=880 kg/m² V =...

1. ***present all the calculations*** Part I: The density of seawater is approximately 1.027g / cm3 and the ice density 0.93g / cm3. United Nations Iceberg (iceberg), generally has a mass of 150,000 metric tons (1 metric ton = 1000kg). Calculation (a) The buoyant force exerted by the water on the "iceberg", (b) the volume of the iceberg above sea level, (c) the volume fraction above sea level. Part II: A metal bucket with a height of 0.700 m and...

mass of One way of restating Archimedes' Principle is that the mass of a block that is floating in a fuid is equal to the the fluid displaced by the block. Imagine that we have a solid block in which all of the sides are 1 cm long-a cube with a volume of 1 cm (Fig.A1.4.2A). We set it in a beaker of pure water and find that, when the block and water come to rest, 70% of the block...
