Title
The figure shows four cubes of the same volume at rest in a container of water. Cube C is partiallysubmerged. Cubes A, B, and D are fully submerged, with B resting on the bottom of the container. Which of thefollowing correctly ranks the densities (r) of
A 1.0-cm-radius hose with a 0.50-cm-radius exit nozzle is being used to fill a 1,000-ml beaker with oil (1,000ml = 0.0010 m3). The velocity of the oil in the hose is v = 0.40 m/s as shown in the figure. The density of the oil is960 kg/m3, and the atmosphe
Blood cells pass through an artery that has a buildup of plaque along both walls, as shown in the figure.Which of the following correctly describes the behavior of the blood cells as they move from the right side of thefigure through the area of plaque? A
The force on the bottom of a swimming pool must increase when a person is floating in the pool. Explain thisbehavior(A) using Newton’s third law.(B) by referencing the water level in the pool.
A river narrows as it passes through a canyon.(A) What happens to the volume flow rate of the water in the river as it passes through the canyon? Explain usinga conservation law.(B) What happens to the speed of the water in the river as it passes through
A beaker of water rests on an electronic balance, as shown in the figure. A mass suspended from a springscale is lowered into the water. Location 1 is above the water. Location 2 is just below the surface of the water.Location 3 is just above the bottom o
Derive an equation to show that the buoyancy force is equal to the weight of water that is displaced by a floating object.
A block of wood floats in water with one-third of its volume submerged. What does this tell you about the wood?
A hose with a 2-cm radius supplies water to fill a pool. Water flows out of the hose at a rate of 6 m/s. The poolhas a length of 12 m, a width of 9 m, and a depth of 2 m.(A) What is the volume flow rate of the water exiting the hose?(B) How many hours doe
Two blocks of the same dimensions are floating in a container of water, as shown in the figure. Which of thefollowing is a correct statement about the two blocks?
