tube is partially filled with sea water, whose density is known to be ρ1 = 1.024cm g3. At the right end, an oily liquid of unknown density ρ2 is added. Since oil and sea water are immiscible, an interface is formed, as shown in the figure below. The heights of the

6. A rock with a mass of 540 g in air is found to have an apparent mass of 300 g when submerged in water with a density of 997 kg/m³. (a) What mass of water is displaced? (b) What is the volume of the rock? (c) What is the average density of the rock?

6. A solid aluminum bar weighs 89 N in air. a. What is its volume? b. If it is suspended from a rope and totally submerged in water, what is the tension in the rope?

You need to determine the density of a ceramic statue. If you suspend it from a spring scale, the scale reads 28.4 N. If you then lower the statue into a tub of water so that it is completely submerged, the scale reads 17.0 N. What is the density?

Mercury is poured into a U-tube as shown in Figure a. The left arm of the tube has cross-sectional area A1 of 10.3 cm2, and the right arm has a cross-sectional area A2 of 4.70 cm2. Two hundred grams of water are then poured into the right arm as shown in Figure b.   (a) Determine the length of the water column in the right arm of the U-tube. cm(b) Given that the density of mercury is 13.6 g/cm3, what distance h does the mercury rise in the left arm? cm

A piece of copper has a mass of 2.6 kg. a.What is the volume of this piece of copper?  b.The copper is then totally submerged in water. What is the buoyant force acting on it?  c. What is the piece of copper’s apparent weight in the water?

A scientist is calculating the density of an ore sample. The scien- tist measures that the ore sample weighs 22.4 N in air. When the sample is suspended by a thin light cord and totally immersed in water, the tension in the cord is 14.2 N. What is the density of the ore sample that the scientist calculates. You can assume that any buoyant force from air is negligible.

Hi please help: A cylindrical container with a cross-sectional area of 69.2 cm^2 holds a fluid of density 856kg/m^3. At the bottom of the container the pressure is 128kPa. Assume Pat= 101kPa A. What is the depth of the fluid? B. Find the pressure at the bottom of the container after an additional 2.25x10^-3m^3 of this fluid is added to the container. Assume that no fluid spills out of the container

8. A rock is suspended by a lightweight string. When the rock is in the air, the tension in the string is 39.2 N. When the rock is totally submerged in water, the tension is 28.4 N. When the rock is totally submerged in an unknown liquid, the tension is 21.5 N. What is the density of the unknown liquid?
