Explain how a barometer works.
A block of cork density 240 kg/m^3 and volume 0.25 m^3 floats in water. What is the weight of the block?
Water passes through a closed piping system starting at point 1 and exits to the atmosphere at the highestpoint near point 4. The pipe is small at point 1 but then widens out to a constant radius for the rest of the pipe.(A) Rank the velocity of the water
Four differently shaped sealed containers are completely filled with alcohol, as shown in the figure. Containers Aand B are cylindrical. Containers C and D are truncated conical shapes. The top and bottom diameters of thecontainers are shown.Which of the
A string holds a 10-cm × 10-cm × 20-cm block of wood with a density of 600 kg/m3 underwater, as shown in thefigure.Draw a force diagram, making sure that all the forces are drawn to relative scale.
1.) A garden hose has an internal diameter of 0.85 cm and a nozzle with a 0.35 cm diameter. If 0.53 m3 of water flows through the hose, what is the speed of water through the hose and through the nozzle. 2.) A 1.5 m high tank is filled with water. A hole
An air bubble is released from the bottom of a swimming pool and ascends to the surface.(a) In a clear, coherent, paragraph-length response, describe any changes in the bubble size and describe themotion of the bubble as it ascends to the surface. Explain
A very tall cylinder with a movable piston is placed in a lake. The piston is pulled up, drawing lake water in andupward, as shown in the figure.In a clear, coherent, paragraph-length response, explain why the lake water moves up the cylinder when thepist
Two blocks of different sizes and masses float in a tray of water. Each block is half submerged, as shown inthe figure. Water has a density of 1,000 kg/m3. What can be concluded about the densities of the two blocks?
Water flows at 8 m/s from two 3-cm-diameter pipes into one 6-cm-diameter pipe. Does the water speed up or slow down upon entering the 6-cm pipe? Justify your answer.
