Title
The figure shows a gas trapped in a spherical container connected to a tube filled with oil that has a density of930 kg/m3. The top end of the tube is open to the atmosphere, which has a pressure of 100 kPa.Is the pressure of the trapped gas higher or low
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.
Water flows at 8 m/s from two 3-cm-diameter pipes into one 6-cm-diameter pipe. Calculate the speed of the water in the 6-cm pipe.
A mass (m) is suspended in a fluid of density (r) by a thin string, as shown in the figure. The tension in thestring is T. Which of the following is an appropriate equation for the buoyancy force? Select two answers.
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.The force on
Explain the physics mechanism that results in the buoyancy force.
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
Explain Pascal’s principle.
The figure shows a gas trapped in a spherical container connected to a tube filled with oil that has a density of930 kg/m3. The top end of the tube is open to the atmosphere, which has a pressure of 100 kPa.The oil is higher on one side by the distance h
Explain how a barometer works.
