(S_0_3)(S_0_2x/3)(S_0_9-x-y)1 dzdydx
Performing first integration
(S_0_3)(S_0_2x/3) 9-x-y dydx
Performing Second Integration
(S_0_3) 6x-(2x^2)/3 - (2x^2)/9 dx
Performing Third Integration
3x^2-(2x^3)/9-(4x^3)/54 | plugging 3 in for all x values gives you a final value of 19.
A piston-cylinder device initially contains 10 kg. of water at a temperature of 85 C. The cylinder has a section area of 0.12 meter square and the piston has no mass. A linear spring (spring constant 120,000 N/m) is touching the piston as shown but exerts no force on it initially. Then heat is...
