Oil having a density of 930 kg/m3 floats on water. A rectangular block of wood 4.00 cm high and with a density of 960 kg/m3 floats partly in the oil and partly in the water. The oil completely covers the block. How far below the interface between the two liquids is the bottom of the block?

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 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

A small statue in the shape of a falcon is painted black and has a weight of 24.1 N. The owner of the statue claims it is made of solid gold. When the statue is completely submerged in a container brimful of water, the weight of the water that spills over the top and into a bucket is 1.25 N. Find the density of the metal. Is the falcon solid gold?

Mercury is poured into a U-tube as shown in Figure a. The left arm of the tube has cross-sectional area A, of 9.8 cm², and the right arm has a cross-sectional area A, of 5.50 cm². Two hundred gra 8 ст of water are then poured into the right arm as shown in Figure b. Water A1 Ag A1 Mercury Densities: Mercury 13.6 g/cm³, Water 1.0 g/cm³ (a) Determine the length of the water column in the right arm of the U-tube. cm (b) What distance h does the mercury rise in the left arm? cm. (c) In figure b, at the level of the dashed line, which side of the u-tube has larger pressure? O Mecure side Water side Same

What is the pressure in the liquid 8.3 m below the surface? The pressure at the surface of the liquid is 108 kPa, and the density of the liquid is 0.74 kg/m3. Use g = 9.8 m/s2 for the acceleration due to gravity

A tank holds a large amount of water. A pipe is connected to the tank at the upper end and is open to the air at the lower end (see figure).The upper end of the pipe has a diameter of 17.0 cm. The lower end of the pipe has a diameter of 8.60 cm. The speed of the water at the upper end is 2.00 m/s.What is the flow rate of the water in the pipe?

If the human body has an average density of 971 kg/m3, what fraction of a person is submerged when floating gently in fresh water?

The figure below shows a horizontal pipe with a varying cross section. A liquid with a density of 1.65 g/cm³ flows from left to right in the pipe, from larger to smaller cross section. The left side's cross-sectional area is 10.0 cm², and while in this side, the speed of the liquid is 2.72 m/s, and the pressure is 1.20 × 105 Pa. The right side's cross sectional-area is 4.00 cm². (a) What is the speed (in m/s) of the liquid in the right side (the smaller section)? (Enter your answer to at least three significant figures.) m/s (b) What is the pressure (in Pa) of the liquid in the right side (the smaller section)? Pa
