Find vc(t) for t ≥ 0 (in v), assuming the switch was open for a long time when closed at t = 0.

assume the capacitor and inductor are initially uncharged.

(1) 3 – 4e–2t + e–8t

(2) 2 – e–2t + 2e–8t

(3) 6 – 6e–4t + 2e–6t

(4) 6 – 6(1+ t)e–8t

(5) 3 + (1+ 4t)e–2t

(6) 3 + [–cos(4t) + 4sin(2t)]e–2t

(7) 3 + [–4cos(4t) + sin(t)]e–t

(8) 3 + [–2cos(4t) + 4sin(2t)]e–4t

(9) none of the above

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)
