The figure shows four cylinders of various diameters filled to different heights with the same fluid. A hole in theside of each cylinder is plugged by a stopper; all of the stoppers are identical. All of the cylinders are open at thetop.(A) Rank the press
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
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
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.
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
If objects that are denser than water sink, how can a steel ship float?
A beaker of water sits on a balance. A metal block with a mass of 70 g is held suspended in the water by aspring scale in position 1, as shown in the figure. In this position, the reading on the balance is 1,260 g, and thespring scale reads 120 g. When th
You and a friend are taking a cruise when the ship begins to sink. The life rafts hold heavy containers ofsupplies. Your friend says, “We need to tie ropes to the containers, toss them overboard, and let them hangsubmerged below the raft. That will allow
The ratio of the diameters of the small piston to the large piston of a hydraulic lift is 1:10. Find (a) the ratio of the force on the small piston to the force on the large piston and (b) the ration of the pressure on the small piston to the pressure on
Explain why objects with a density greater than that of water will sink. Prove your explanation with an equation.
