Problem 3 A lead block with mass m = 1000kg is placed on top of a...
1) What mass (in kg) of iron must be placed on top of the wood block so that the wood block is just barely submerged (the top of the block of wood is level with the surface of the water and the iron on top is in the air). The volume of the wood block is 0.00782 m^3. The density of the wood is 620 kg/m3 and the density of the water is 1000 kg/m3. 2) Most cars have hydraulic...
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...
a cubical block of wood (density 850 kg/m^3) of height 28cm floats in water( density 1000kg/m^3). What is the height of the block above the surface of water? a)5.1cm b)4.2cm c) .92 cm d) 10.8 cm e) 1.11 cm
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...
A hot block of iron is placed on top of a block of ice at Ti water = -60° C in an insulating container so no heat can be transferred into or out of the container. When you open the container later the ice has completely melted. For the physical system of the iron and water, what energy systems changed from the time the iron is placed insided to the time the container is opened
A piece of rubber of density of volume 0.1m^3 is placed under water (density 1000kg/m^3. If its initial acceleration is 3 m/s^2 up, wht is the density of the rubber in kg/m^3?
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 =...

A hot block of iron is placed on top of a block of ice at Tiwater--60° C in an insulating container so no heat can be transferred into or out of the container. When you open the container later the ice has completely melted. For the physical system of the iron and water, what energy systems changed from the time the iron is placed insided to the time the container is opened?

A cube of wood 20cm on each side floats in water so that 7cm is above the surface of the water and 13cm is below. a)What is the density of the wood? ( You must justify your answer) b) How much force would have to be exerted on the wood to submerge it? c) what volume of lead mass has to be placed on top of the block of wood so that it will just be totally submerged? d)Suppose a...
