Archimedes' principle: Fish submerged in water on balance beam.

• C+30+20

Archimede's principle: Fish submerged in water on balance beam. Both platform balances 'A' and 'B' are initially balanced. Labjack raises 'B' until fish is submerged in water. System 'A' is unbalanced by the same amount as System 'B'. Weight 1 from 'A' is transfered to 'B', and both systems are again in balance. Mass of fish = 50 gms, Fish submerged = 33 gms, Amount fish displaces = 17 gms, Weight 1 = 17 gms, Weight 2 = 33 gms, Mass of fish = Weight 1 + Weight 2 FLUID STATICS.
