• Buoyant force as applied to an iron block submerged in water

  Other one is the weight of the block Buoyant force is the weight of the liquid displaced by the submerged part. Here the whole block is submerged.

• Buoyant Force in Equilibrium of Submerged Block

  20535 Buoyant Force in Equilibrium of Submerged Block A block of plastic whose mass is 25 kg and whose density is 850 kg/m^3 is tied by a corfd to the bottom of a pool of seawater whose density is 1025 kg/m^3. Find the force in the cord.

• Archimedes' Principal: Buoyant force

  When the block is fully lowered in the water a buoyant force will act on the block, which is in upward direction.

• Archimedes principle to find density of a block floating in water and density of the oil

  Recall that the buoyant force exerted on a floating or submerged object is the density of the liquid times the gravity constant g, times the submerged volume: (1) buoyant force = D g Vsub Note 2.

• Buoyant Force, Projectile Range

  V - V' = voume of block under water While floating : Upthrust = Weight of block Buoyant force = Weight of block (V-V' )*1000*9.8 = V*669*9.8 (V- V')*1000 = V*669 1000V - 1000V' = 669V 331V = 1000V' V' = 0.331V = 0.331*2.836*10^-4 = 0.9387

• An object is held stationary by a cable near the sea floor. Find the cable tension.

  SEE ATTACHMENT #1 for a diagram showing all vertical forces on the wood block in terms of known parameters. Since the block is stationary, the total upward force must equal total downward force on it.

• Archimedes' principle applied to a floating block in turpentine gives density of liquid.

  From 'net vertical force = 0'; when floating, the buoyant force must equal the force of gravity on the block.

• equilibrium readings of scales

  So, the buoyant force equals rho_oil V g, where V is the volume of the iron, which is m/rho_iron.
