8. ### Archimedes’ Principle

1. (a)(i) weight of person = 50g N where g is the acceleration due to gravity (ii) Upthrust = 50g N (iii) Weight of water displaced = upthrust = 50g N 2. Upthrust = 1.2 x 0.05g N = 0.06g N 3. (a) Weight = 7800 x (0.5^3)g N = 975g...

9. ### Archimedes’ Principle

(b) Upthrust on box = 450 kN Hence, weight of water displaced = 450 kN Mass of water dispalced = 450000/g kg = 4.587 x 10^4 kg Volume of water dispalced = 4.587 x 10^4/1025 m^3 = 44.75 m^3 Thus, h = 44.75/(pi x 2.5^2) m = 2.279 m (c) Pressure at half...

10. ### Archimede principle

Volume of air displaced by the balloon = 2000 m^3 Upthrust on the balloon = weight of air displaced = 2000 x 1.25g N = 25000 N where g is the acceleration due to gravity, taken to be 10 m/s^2 Weight of hot air inside balloon = 2000 x 0.95g N...
