1. A block of wood has a mass of 25 kg and a density of 650 kg/m'. You are holding it under water by pushing downward. a) What is the volume of the block of wood? b) What is the buoyant force on it? c) What is the magnitude of the downward force you are exerting to hold the block under water? 2. In the diagram, the hinge is frictionless and the system is in equilibrium. The uniform beam...
A block of wood of mass 2kg floats in water, and it is noted
that volume is 3/4 is submerged. density of water 1000
kg/m3.
a) What is the buoyant force of the block? hint:
V is volume and g is 9.81 m/s2.
b) What is the density of the block?
Calculate the buoyant force that would be exerted on a wood cylinder if you held it under water. How much force must you exert to keep it submerged?
a) A block of wood (density 600 kg / m3) has a length of 40 cm, a width of 30 cm and a height of 20 cm How much percentage of the total volume is submerged in oil of density 950 kg / m ^ 3? b) Force required to remove a circular plug of 0.02 meters radius from a bathtub whose water level is 0.5 m high with respect to the bottom of it? Consider the density of water...
A force of 10.0N is required to keep a 1.0 kg piece of wood submerged to a depth of 1.0 m . what force in (N) is required to keep it submerged to 3 0 m?
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...
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 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...
The density of a block of wood is 604 kg/m3. When this block is floating in water, what fraction of its volume is submerged?
When a block is completely submerged under water, the buoyancy force on it is 11.6N; when it is completely submerged under an unknown liquid, the buoyancy force is measured to be 10.5N. What is the density (in unit of kg/m3) of the unknown liquid?
