A cube of side L whose density is 2 g/cm3 floats half submerged in a liquid of density 4 g/cm3 as shown in Figure 1. A student pours water from density 1g/cm3 until she barely covers the cube as shown in figure 2. a) Determine the height (h) as a function of L that the cube remains submerged in the density liquid of 4g/cm3. (Water and liquid do not mix.)

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

Water flows in a pipe as shown in the picture. At point A, the pipe diameter is 18 cm and the speed of the water is 8.0 cm/s. At point B, the pipe diameter is 9 cm. What is the speed of the water at point B. В А

A geologist finds that a moon rock whose mass is 8.25 kg has an apparent mass of 6.15 kg when submerged in water. What is the density of the moon rock? Given that the density of water is 1,000 kg/m³. Include a diagram of the situation.
