Exp#7:- principle of Archimedes_Idea:- The body submerged in a liquid removes the size of the liquid equal to the size of the bode. _Elements:-A small metal ball –Water-Balance-Glycerin. -Steps:- -Weigh the weight of the ball in the air and a weight of M.-Weigh the weight of the ball in the water and to be m.-Weigh the weight of the ball in another liquid such as glycerin and to be m1. -find mass of water displaced from the relationship V=M-m-Find mass of glycerin displaced from the relationship V=M1-m-To find a specific density using the relationship M/M-m -Specific gravity Allgelsrin M-m1/M-m
-Calculations and results:- • -weight the ball in the air =M=35g. • -Weight the ball in the water =m=31g. • -weight the ball in the glycerin =m1=30g. • Mass of water displacement =mass the ball in the air – mass in the mater • =M-m • =4g. • Cluster quality of iron=M/M-m =35/35-31 =8.7 • Cluster quality of glycerin=M-m1/M-m =35-30/35-31=1.2
-Conclusion:- lada immersion in a liquid the body weight decreased by weight of the liquid was displaced. No he lada body immersion in a liquid it is strongly in fluenced by the payment of this topic to the top and Force is equal to the weight of fluid displacement.
