Archimedess Principle1. Weight = mass x 9.80 g/cm3W= 45g x 9.80 NW= 44,100 dynes2. pleased force ( deliberate) = weight in aerate weight in water supplyBF = 44,100 dynes 38710 dynesBF = 5390 dynes3. hatful of Water = radius2 x lengthV= (.63cm) (4.65cm)V= 5.80 cm 4. Buoyant force (measured) = mass in air/ tautnessBF= (44,100 g) / (7.76 g/cm3)BF= 5684 cm35. % difference = BF calculated BF measured/ BF measured% difference = 5390 5684 / 5684% difference = 5.4 %6. Density = Mass / VolumeDensity = 45 g / 5.80 cm3Density = 7.76 g/cm37. Volume of wood = length x breadth x heightV = (7.62cm) (7.63cm) (3.86 cm)V = 224. 42 cm3Questions2.) Because an overweight person displaces much fluid when stepping into a pool. By displacing more fluid, the person creates a greater buoyant force making it easier for him to swim.5.c) By placing a battery into the water with a floating rod into its late cylindrical cavity it is quite easy to determine the condition of the battery. The diluted ba ttery will have a much higher tautness than that of a highly charged battery. From the observation of how the battery floats you can attest its condition.8.) We were able to find the volume of displace water in recrudesce II quite easily. First we placed a large tupperware container on the table and in it a small container filled to the top with water. When the embarrass of wood was placed in the container, water fell out of the smaller container into the larger container. By placing the water which fell out of the smaller container into a cylinder, you are able to measure the volume of displaced water.9.) No I did non use Archimedess principal to find the densities. I used the density formula of dividing the mass by the volume. We find the densities and compare them to the densities of water to serve understand the mechanics of buoyant force.DiscussionIn part devil of the lab dealing with Archimedess principle, we were comparing the buoyant force of a block of wood to its w eight in dynes. The first step of the execution dealt with measuring the quantity of displaced water. We did this using two containers, whizz small and one large, and filled the small container to the brim with water. By placing the block of wood in the small container and using a graduated cylinder, we were able to find the mensuration of water displaced by the block.
