A plastic sphere floats in water with 45.0% of its volume submerged. This same sphere floats in glycerin with 35.9% of its volume submerged. (a) Determine the density of the glycerin. kg/m3 (b) Determine the density of the sphere. kg/m3
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...
A plastic sphere floats in water with 35.0% of its volume submerged. This same sphere floats in glycerin with 28.0% of its volume submerged. (a) Determine the density of the glycerin 10204.08 X Your response differs from the correct answer by more than 100%. kg/m3 (b) Determine the density of the sphere. kg/m3
2. Iron is denser than plastic. When fully submerged in water, is the buoyant force on a solid iron sphere greater than, less than, or equal to the buoyant force on a solid plastic sphere of the same diameter? Explain your answer using the buoyant force equation. a. b. If you instead fully submerge each sphere in ethylene glycol, does the buoyant force on each sphere increase, decrease, or stay the same. Explain your answer using the buoyant force equation....
5)A plastic sphere floats in water with 70.0% of its volume submerged. This same sphere floats in glycerin with 55.6% of its volume submerged. (a) Determine the density of the glycerin. kg/m3 (b) Determine the density of the sphere. kg/m3
A plastic sphere floats in water with 45.0% of its volume submerged. This same sphere floats in glycerin with 35.8% of its volume submerged (a) Determine the density of the glycerin. 450 Your response differs from the correct answer by more than 10%. Double check your calculations. kg/m3 (b) Determine the density of the sphere. 1168.83 Your response differs from the correct answer by more than 100%. kg/m3
A smooth rectangular box of weight 5,125 N floats to a depth 2.3 m in water. What is the area of its bottom surface? The density of water is 1000 kg/m3. Use the value of g = 9.8 m/s2 for the acceleration of gravity.
2. 95% of a wood block is submerged in water (density= 1000 kg/m). A layer of oil with a density of 880 kg/m' is now poured on top, to a depth that more than covers the block, as shown. Find the resulting new volume fraction submerged in water, V(in water) / V(block). Hints: (i) You get two buoyant forces - one for each liquid; Also note that (ii) volume, V(block) = V(in water) + V(in oil). d=880 kg/m² V =...
