A plastic cube (density 973 kg/m³) has side length 1.90 cm. You drop the cube into a jar of maple syrup (density 1131 kg/m³) -you don't know why- and observe that it floats in the syrup . What percentage of the plastic cube is submerged?

A block of wood has a mass of 3.51 kg and a density of 631 kg/m3. It is to be loaded with lead (1.13 x 104 kg/m³) so that it will float in water with 0.919 of its volume submerged. What mass of lead is needed if the lead is attached to (a) the top of the wood and (b) the bottom of the wood? (a) Number i Units (b) Number i Units

A rock with density 2100 kg/m3 is suspended from the lower end of a light string. When the rock is in air, the tension in the string is 33.0 N. What is the tension in the string when the rock is totally immersed in a liquid with density 750 kg/m3?

Four objects are placed in a tank of water. Each object is fully submerged and released from rest.The table gives the density and volume of each object. Rank the five objects by the buoyant forceacting on each after being released from least to greatest. "<" and"=". ( "W<X= Y < Z")

You come across an open container that is filled with two liquids. Since the two liquids have different densities, there is a distinct separation between them. Water, which has a density of pw = 1.00 × 10³ kg/m³, fills the lower portion of the container to a depth of 0.212 m. The fluid that is floating on top of the water is 0.335 m deep. If the absolute pressure on the bottom of the container is 1.049 × 105 Pa, what is the density, p₁, of the unknown fluid? The acceleration due to gravity is g = 9.81 m/s² and atmospheric pressure is Po= 1.013 × 105 Pa. P₁ = kg/m³

c) A crane lifts the 16,000 kg steel hull of a sunken ship out of the water. Determine: i. the tension in the crane’s cable when the hull is fully submerged in the water ii. the tension when the hull is completely out of the water. (density of water = 1.0 x103 kg/m3 ; density of steel = 7.8 x103 kg/m3 )

A block of wood has a mass of 3.50 kg and a density of 606 kg/m3. It is to be loaded with lead (1.13 x 104 kg/m3) so that it will float in water with 0.874 of its volume submerged. What mass of lead is needed if the lead is attached to (a) the top of the wood and (b) the bottom of the wood? (a) Number Units (b) Number Units
