The figure shows four cylinders of various diameters filled to different heights with water. A hole in the side ofeach cylinder is plugged by a cork. All cylinders are open at the top. The corks are removed. Which of thefollowing is the correct ranking of
Cube 1 has a density of p, volume of V, a mass of m, and a side dimension of x. Cube 2 is made of the samematerial and has a side dimension of 2x. What are the density, volume, and mass of cube 2 in terms of p, V, andm?
Explain the physical mechanism by which water exerts pressure on the side walls of a glass in which it is contained. Make sure your answer addresses the microscopic scale of matter.
Explain how a barometer works.
A raft with dimensions floats partially submerged in the ocean, as shown in the figure. The density of theocean water is r. Atmospheric pressure is Patm.(A) Write an algebraic equation for the water pressure exerted on the bottom of the raft.(B) Write an
You visit a store and see a beach ball floating above a fan as shown in the figure. You notice that when thebeach ball begins moving out of the air stream, it is pushed back toward the center of the stream. Explain why theballoon remains stable in the air
Fluid enters the left side of the flow tube and exits the right side at a higher velocity, as predicted by the continuityequation.Fill in the pressure-energy density bar chart for the fluid-earth system, and use it to explain changes in thefluid pressure
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?
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
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
