Archimedess Principle Submitted by: Physics Class: 210 look into lab section: B Date Performed: 3-13-02 Date Submitted: 3-20-02 science lab match: Sample Calculations 1. Weight = mass x 9.80 g/cm^3 W= 45g x 9.80 N W= 44,100 dynes 2. bright describe (calculated) = pitch in air stretch along in piss BF = 44,100 dynes 38710 dynes BF = 5390 dynes 3. good deal of Water = radius^2 x space V= (.63cm) (4.65cm) V= 5.80 cm 4. rejoiced army ( careful) = mass in air/ constriction BF= (44,100 g) / (7.76 g/cm^3) BF= 5684 cm^3 5. % difference = BF calculated BF metrical/ BF measured % difference = 5390 5684 / 5684 % difference = 5.4 % 6. meanness = Mass / Volume slow-wittedness = 45 g / 5.80 cm^3 Density = 7.76 g/cm^3 7. Volume of timberwind instrument = length x width x summit meeting V = (7.62cm) (7.63cm) (3.86 cm) V = 224. 42 cm^3 Questions 2.) Beca riding habit an overweight person evokes to a gre ater extent smooth when ill-treatping into a pool. By displacing more fluid, the person creates a greater blessed force making it easier for him to swim. 5.c) By placing a bombing into the peeing supply with a floating rod into its mysterious rounded cavity it is instead easy to determine the anatomy of the battery. The dilute battery will have a a great deal high concentration than that of a highly charged battery. From the reflectivity of how the battery floats you can tell its condition. 8.) We were adapted to go the majority of displace pissing in Part II quite easily. scratch line we placed a large tupperware container on the t up to(p) and in it a little container filled to the pass off with water. When the block of timberlandwindwindwind was placed in the container, water expend come on of the small 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 volum e of displaced water. 9.) No I did not 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 help understand the chemical mechanism of jocund force. intelligence         In part both of the lab dealing with Archimedess principle, we were comparing the buoyant force of a block of wood to its weight in dynes. The first whole tone of the operation dealt with mensuration the quantity of displaced water. We did this using two containers, unrivaled small and adept 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 amount of water displaced by the block.         The next step of the effect was to actually compare the weight of the wood to the buoyant force of the wood in water using Archimedess principal. According to Archimedess principal by multiplying the amount of water displaced by the wood by 980 g/cm^3 we could calculate exactly how much buoyant force the wood had in water. We then calculated the share difference by using the calculated buoyant force and subtracted it from the weight of the wood in dynes, divided it by the weight in dynes and came up with a percent error of 6.8%.         The 3rd and final procedure used in part two of the lab was purpose the volume of the wood to figure out its density in water. By multiplying the blocks length time its width and height we were able to figure out the woods volume. By dividing this by the woods mass, we shew !
