A 1000 kg drawbridge is kept at an elevated state by a chainattached to the castle wall right above the end of the bridge thatforms a 90 degree angle with the bridge. The length of the bridgeis 3.00 m; the length of the chain is 4.00 m.a) Find the tension in the chain.b) Find the magnitude and direction of the force exerted on thebridge by the hinge.
Please help. I have a physics exam, and this is the practiceexam.
Note: Please disregard the work done on the graph because it iswrong! And plz show step by steps in details so I can understand it(trying to study for exam ;) Thanks so much!
The arrow OA in the PV diagram shown in Figure OQ22.11 represents a reversible adiabatic expansion of an ideal gas. The same sample of gas, starting from the same state O now undergoes an adiabatic free expansion to the same final volume. What point on the diagram could represent the final state of the gas?
(a) the same point A as for the reversible expansion, (b) point B, (c) point C, (d) any of the choices, and (e) none of those choices.
