$$y = {e^{ - 2x}}$$ is a solution of the differential equation $$\,{y^{11}} + {y^1} - 2y = 0$$

Write down the sequence of Instructions which are actually (till HLT instruction), if the program begins with the location 1FF5H.

The circuit shown in the figure, is initially in its steady state. Switch is opened at t = 0.
(1) Determine the initial voltage, V_C(0^-), across the capacitor, and the initial current, i_L(0^-) , through the indicator.
(2) Calculate the voltage, V_L(t) , across the inductance for t > 0.

Calculate the frequency at which zero- transmission is obtained from the Wien- bridge shown in Fig.
