The Buoyant Force is calculated by (fluid density)(volume of displaced fluid)(acceleration due to gravity). How does changing the shape of an object relate to the Buoyant Force and the object's density? A. By changing the shape of the object we manipulate both the weight of displaced fluid and the density of the object. Thus we can change the Buoyant Force on the object and change the density, making it possible for heavy objects to float, hover or rise in a...

3. The density of bubble-filled ice from your refridgerator is 900 kg/m?. You have an ice cube that is 28 mm wide x 40 mm long x 10 mm high which floats in a large glass of a sugar-sweetened drink with a density of 1.05 g/cm". Part of the ice pokes up above the liquid. a) What is the cube's weight F? b) What volume Vdisp of drink displaced by the ice would be needed to provide a buoyant force...

The
mass is 25 grams. Please label and put a box around the
solution.
Purpose: To calculate the apparent weight of a mass when immersed in water. Students will also have the opportunity to learn how to use calipers to accurately measure lenghs. Background: Archimedes discovered that he could find the density of an object by comparing it's weight o its apparent weight when immersed in water (see example 10-8 in he textbook). When mmersed, the buoyancy due to the...

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...

Can you use Archimedes' principle to find the density of an object that floats? a. Yes, attach a weight to the object and find the difference in buoyant forces. b. No, the object must be able to sink. c. Yes, a floating object will still displace fluid equivalent to the buoyant force.

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...

3) Yellow pine has a mass density of 0.55 g/cm3. Suppose you have a wooden yellow pine cylinder with a volume of 8.3 cm3 . A) What is the mass of the cylinder? B) What is the weight of the cylinder (the force due to gravity)? C) If you immerse the cylinder in water, what will the buoyant force on it be? D) What do your results from parts B and C imply?

5. The buoyant force is a consequence of the fact that pressure varies with depth. To understand this, do the following, for a vertical cylindrical object that is submerged in a liquid: a. If the liquid pressure at the top of the cylindrical object is P, write an expression for the liquid pressure at the bottom of the cylinder of length L. b. Write expressions for the magnitude of the force that the liquid exerts at the top of the...

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,...
