If the voltage waveform depicted below is applied across the terminals of a 2 mF capacitor, determine the expressions and plot the following: (a) The resulting current, i(t). (b) The resulting power, p(t). (c) The resulting energy, w(t). Clearly indicate the value on the y-axis for the limits of each time interval. Is energy being stored or delivered by the capacitor? What is the value of the maximum energy stored in the capacitor?

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
