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.
A container is filled with water, as shown in the figure. A spigot is opened at the bottom of the container, and waterflows out.Use Bernoulli’s equation to derive an equation for the exit velocity of the water.
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 variable-diameter pipe is used to supply water to a sprinkler system. Which of the sprinklers shown in thefigure will squirt water the highest? Justify your claim.
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.
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 block of cork density 240 kg/m^3 and volume 0.25 m^3 floats in water. What is the weight of the block?

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 the physics mechanism that results in the buoyancy force.
