Pure water has a surface tension of 0.0728N/m. Soap water has a surface tension of 0.025N/m. A soap boat was made with a mass of 0.5g and a square surface area of 2cm x 2cm. Show that the soap boat can stay afloat on both pure water and soap water solely with the force of surface tension. Calculate the acceleration of the boat on pure water when a drop of soap is added to the rear edge of the boat if the angle from the vertical is 40 degrees.

A flotation device is in the shape of a right cylinder, with a height of 0.500m and a face area of 4.00m2 on top and bottom, and its density is 0.400 times that of fresh water. It is initially held fully submerged in fresh water, with its top face at the water surface.Then it is allowed to ascend gradually until it begins to float. How much work does the buoyant force do on the device during the ascent?
The density of a floating body can be determined by tying weights to the body until both the body and the weights are completely submerged, and then weighing them separately in air. Consider a wood log that weighs 1540 N in air. If it takes 34 kg of lead (r 5 11,300 kg/m3) to completely sink the log and the lead in water, determine the average density of the log.
The truck carries an open rectangular container that is 3.9m wide, 3.0m deep and 5.0m long, contains oil of density 811kg/m³ to a depth of 2.1m. If it has a constant acceleration of 6.9m/s². Determine the total force(in kN) acting at the rear wall of the container.
It is said that Archimedes discovered the buoyancy lawswhen asked by King Hiero of Syracuse to determinewhether his new crown was pure gold (SG = 19.3).Archimedes measured the weight of the crown in air to be11.8 N and its weight in water to be 10.9 N. Was it pure gold?
Balloons are often filled with helium gas because it weighs only about one-seventh of what air weighs under identical conditions. The buoyancy force, which can be expressed as Fb = ρairgVballoon, will push the balloon upward. If the balloon has a diameter of 12 m and carries two people, 85 kg each, determine the acceleration of the balloon when it is first released. Assume the density of air is ρ = 1.16 kg/m3 , and neglect the weight of the ropes and the cage.
A cylindrical disk ofwood weighing 45.0 N and having adiameter of 30.0 cm floats on a cylinderof oil of density 0.850 g /cm3(Fig.). The cylinder of oilis 75.0 cm deep and has a diameterthe same as that of the wood.(a) What is the gauge pressure at thetop of the oil column? (b) Supposenow that someone puts a weightof 83.0 N on top of the wood, butno oil seeps around the edge of thewood. What is the change in pressureat (i) the bottom of the oil and(ii) halfway down in the oil?
A narrow, U-shaped glasstube with open ends is filled with25.0 cm of oil (of specific gravity0.80) and 25.0 cm of water on oppositesides, with a barrier separating theliquids (Fig.). (a) Assume thatthe two liquids do not mix, and find thefinal heights of the columns of liquid ineach side of the tube after the barrier isremoved. (b) For the following cases,arrive at your answer by simple physicalreasoning, not by calculations:(i) What would be the height on eachside if the oil and water had equal densities? (ii) What would the heightsbe if the oil’s density were much less than that of water?
Consider a body of arbitrary shape. If the pressure distribution over thesurface of the body is constant, prove that the resultant pressure force onthe body is zero.
Calculate the density of water vapor at 350 kPa abs and 20C if its gas constant is 0.462 kPa-m3/kg-K
The 100cm radius cylinder weighs 3.1 KN and rest on the bottom of a container which is 1.5 meter long. Oil and water are poured into the left and right portion of the container to the depth of 0.8m and 1.4m respectively. Find the magnitude of the horizontal and vertical components of the force which will keep the cylinder touching the container at B.
A rectangular parallelepiped with a square base d = 0.260 m on a side and a height h = 0.120 m has a mass m = 6.60 kg. While this object is floating in water, oil with a mass density ?o = 710 kg/m3 is carefully poured on top of the water until the situation looks like that shown in the figure. Determine the height of the parallelepiped in the water.
An open barge has the dimensions shown in the figure. If the barge is made out of 5.5-cm-thick steel plate on each of its four sides and its bottom, what mass of coal can the barge carry in freshwater without sinking? Is there enough room in the barge to hold this amount of coal? (The density of coal is about 1500 kg/m3.)
