105.00 L 5.00 kg 0.00 N Fluid Oil Water Weight of 5.00 kg wood block = 49 N Step 2: Place the wood block in the water and notice that it floats. When the wood block rests on the ground, the downward gravitational force is balanced by an upward normal (“contact") force. When floating, the gravitational force is still there, but the normal (contact") force is not. The force exerted by the fluid is the buoyant force (B). When floating,...

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 =...

You will float a wood block in a container filled with water. Derive a formula predicting the percentage of the block submerged. (Hint: This is a problem in fluid statics. The weight of the block must be balanced by the buoyant force). The formula should be expressed as a ratio in terms of the volume of the block, V_block, and the volume of displaced water, V_water. The result should be given in terms of the density of the block, ρ_block,...

A cube of wood having an edge dimension of 22.1 cm and a density of 651 kg/m^3 floats on water. What is the distance from the horizontal top surface of the cube to the water level? If a block is floating, the buoyant force must equal the weight of the block cm What mass of lead should be placed on the cube so that the top of the cube will be just level with the water surface? The block is...

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...
