Find the charge on the capacitor in an LRC-series circuit at t = 0.04 s
when
L = 0.05 h,

R = 3 Ω,

C = 0.02 f,

E(t) = 0 V,

q(0) = 3 C,
and
i(0) = 0 A.

Determine the first time at which the charge on the capacitor is equal to zero. (Round your answer to four decimal places.)

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
