The sphere on the right has 6 times the mass and 2times the radius of the sphere on the left. What is the ratio of the density of the sphere on the right to the density of the sphere on the left? Give your answer in decimal form with two decimals. A block of ice (density 920 kg/m ), a block of concrete (density 2000 kg/m3), and a block of iron (density 7800 kg/m3) are all submerged in the same fluid. All three blocks have the same volume. Which block experiences the greatest buoyant force? O All three experience the same buoyant force O the answer depends on the density of the fluid O the concrete O the ice O the ironA cylinder is completely filled with water. The top of the cylinder is sealed with a tight-fitting lid. If you push down on the lid with a pressure of 1000 Pa, the water pressure at the bottom of the cylinder O increases by 1000 Pa O increases by an amount determined by the height of the cylinder O Increases by more than 1000 Pa O Increases by less than 1000 PaA box has the shape of a cube with 5.00 cm on each side and is immersed in a mystery fluid. Determine the density of the mystery fluid if the gauge pressure at the top surface of the box is 573 Pa and the gauge pressure on the bottom surface is 1,041 Pa. Please give your answer as a whole number with no decimal places.In the figure, an open tank contains a layer of oil floating on top of a layer of water (of density 1000 kg/m3) that is 3.0 m thick, as shown. What must be the thickness of the oil layer if the gauge pressure at the bottom of the tank is to be 5.5.0 x 104 Pa? The density of the oil is 503kg/m . Give your answer in meters with two decimal places. (numerical answer only, no units.) oil X water 3.0 mA raf't oats on a lake with 61 % of its volume under water. If the mass of the raft is 57 kg, what load in kilograms can be placed on the raft without the load getting wet? Please give your answer as a whole number with no decimals
