2. [-/2 Points] DETAILS OBINPHYS8 4.Q.042 MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Pistons are fitted to two cylindrical chambers connected through a horizontal tube to form a hydraulic system. The piston chambers and the connecting tube are filled with an incompressible fluid. The cross-sectional areas of piston 1 and piston 2 are A, and A2, respectively. A force , is exerted on piston 1. Rank the resultant force F2 on piston 2 that results from the combinations of F1. A,, and A2 given from greatest to smallest. If any of the combinations yield the same force, give them the same ranking. (Use only ">" or "=" symbols. Do not include any parentheses eses around the letters or symbols.) a. F1 = 6.0 N; A, = 1.3 m ; and A2 = 2.6 m b. F1 = 3.0 N; A, = 1.3 m"; and A2 = 0.65 m C. F, = 3.0 N; A, = 2.6 m ; and A, = 5.2 m d. F1 = 6.0 N; A, = 0.65 m'; and A2 = 2.6 m e. F1 = 6.0 N; A, = 0.65 m; and A2 = 1.3 m f. F1 - 3.0 N; A, - 2.6 m'; and A2 - 1.3 m? Need Help? Read It Submit Answer 3. [-/2 Points] DETAILS OBINPHYS8 4.P.002.
