A solid cone of diameter 24 cm and --- height 20 cm floats with its vertex downwards in water as shown in figure. Is this cone in stable equilibrium? S=0.8 H.

A closed system consisting of 10 lb of air undergoes a polytropic process from p₁ = 65 lbf/in², v₁ = 4 ft³/lb to a final state where p₂ = 20 lbf/in², v₂ = 11 ft³/lb. Determine the polytropic exponent, n, and the amount of energy transfer by work, in Btu, for the process. Step 1 Your answer is correct. Determine the polytropic exponent, n, for the process. n = 1.16 Hint Step 2 Your answer is incorrect. Determine the amount of energy transfer by work, in Btu, for the process. W = i 462.623 Btu Toutbo dlo Attempts: 1 of 4 used
