An operational amplifier consists of three stages. The first stage is a differential amplifier with Rout = 200 kohms. The second stage is a CE stage with Rin = 200 kohms and A = -100. Neglecting parasitic capacitances determine the approximate value of the capacitor that must be connected across the second stage to place a dominant pole at 10 Hz.

How much power could a wind turbine produce if it had the following specifications? cp = 0.45 -d=1.2kg/m3 d=50m v 5m/s

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
