a block of wood has a density of 0.6 g cm-3 is floating on a surface of water. What porion of wood is outside water |
|
Answer» that a floating body is PUSHED up with a force equal to the gravity of the DISPLACED fluid.Now the question is: What volume of water we need to displace in order to generate a force equal to the gravity of the cube?The mass of the cube = V x Density=0,6kgGravity of the cube is approximately 60N so we need to find out what is the height of a water COLUMN with area 0,1 x 0,1 that has a gravity of 60N. ASSUMING water density 1g/cm3 you can calculate the height being 0,06m (6cm). The answer to the question is 4cm.If is not CLEAR I can write down on a piece of paper. Al you need to know to figure it out by yourself is Archimedes formula and Density formula. |
