Conclusion How does the buoyant force acting on an object compare to the weight of the water displaced by that object? The wood floated; the brick did not. What condition—in terms of forces is required for an object to float? What is the condition for floating in terms of object and fluid densities? What happens to the density of water when it freezes to become ice? Which has more mass - a liter of water or a liter of ice?...

3. Archimedes' Principle states that the buoyant force on an object partially or fully submerged in a fluid is equal to the weight of the fluid that the object displaces. For an object of density po floating partly submerged in a fluid of density pf, the buoyant force is given by F P19 SA(y)dy, where g is the acceleration due to gravity and A(y) is the area of a typical cross-section of the object. The weight of the object is...

Consider a basketball. In which situation will the basketball have the greatest buoyant force? When the basketball is floating on a lake. When the basketball is held under the surface of a pool. When the basketball is placed on the ground. When the basketball is thrown high into the air.

1.How does the buoyant force determined from the mass of the fluid displaced compare with the difference in the dry and wet weights of each object? Is Archimedes' priciple verified? 2.How does the density determined for each object compare with its accepted value? You will have to look up the densities of Al, Cu, and Pb. Note : Discuss with the percent error

Which of the following statements about completely submerged objects resting on the ocean bottom is correct? Select one: a) The displaced volume of fluid is greater than the volume of the object. b) The weight fo the object and the buoyant force are equal and opposite. c) The buoyant force acting on the object is equal to the object's weight. d) The apparent weight of the object depends on the object's density Which of the following is not correct about...

1. Why do astronauts on the International Space Station float, apparently weightless, rather than stand on the floor? (The space station is about 400km above the surface of the Earth) a. There is no gravity in space b. The gravitational field is virtually zero c. The astronauts have no mass in space d. The astronauts and space station are both in freefall e. The gravitational force...

105.00 L 5.00 kg 0.00 N Fluid Oil Water Weight of 5.00 kg wood block = 49 N Step 2: Place the wood block in the water and notice that it floats. When the wood block rests on the ground, the downward gravitational force is balanced by an upward normal (“contact") force. When floating, the gravitational force is still there, but the normal (contact") force is not. The force exerted by the fluid is the buoyant force (B). When floating,...

EST 1) State Archimede's principle. by mass ofme splacid fid 2) Use Archimedes' principle to prove the following: "When a body is floating on a liquid, it displaces a weight of liquid equal to its own weight." 3) How would you determine the density of an irregularly shaped rock? 4) Lead has a greater density than iron, and both are denser than water. Is the buoyant force on...

Does the force of gravity
alone provide the means for the centripetal force, is this why they
are equal ? For explaining why there is no normal force, could you
see it as the astronaut having the same acceleration as the ship
and so the relative acceleration = 0, so it's under the illusion
almost of having no acceleration so there's no force ? Please !! If
you have different reasoning please share. I'm just trying to wrap
my head...
