Title
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 block of wood floats in water with one-third of its volume submerged. What does this tell you about the wood?
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
A very tall cylinder with a movable piston is placed in a lake. The piston is pulled up, drawing lake water in andupward, as shown in the figure.Is there a limit to how high water can be drawn up the piston? Write an algebraic expression that supportsyour
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
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
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
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
Derive an equation to show that the buoyancy force is equal to the weight of water that is displaced by a floating object.
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?
