Question
added to the Container. What is the final temperature of the water and the container when the system reaches equilibrium? (specific heat of water = 4186 J/kg degree C, specific heat of aluminum = 900 J/kg degree C) (15 points). An engine goes through a cyclic process. In the process, the engine does 700 J of work and has a heat output of 2200 J. What is the efficiency of the engine? (30 points). Three point charges are located on the x-axis. The first charge, q1 = +15.0 Mu C, is at x =2.00 m; = +30.0 Mu C, is at the origin; and the third charge, q3 = 10.0 Mu C, is located at x =Explanation / Answer
3) from the given data, heat input = wordone + heat output
= 700 + 2200
= 2900 J
efficiency of engine, e = workone/ heat input
= 700/2900
= 0.2413 or 24.13%
