LCR circuit

Attached is the problem. I need help with the general solution. I know how to get the constants. I am having trouble finding my k1 and k2 values for the problem and getting a general solution. (See attached file for full problem description)

Voltage divider

We want to design a voltage divider circuit to provide an output voltage Vo=5V from a 12V source as shown in the attachment problem, the current taken from the 12 V source is to be 100mA. Find values of R1 and R2.

Thevenin's Theorem

I would like some one to show me how to work out the Thevenin Equivalent Voltage for the attached file. I have only put in resistors in the file the actual problem has a capacitor, resistor and an inductor but I have already converted them to equivalent resistances and worked out the Thevenin Impedance for the circuit.

Solve electrical network problems

Require a logic circuit designing for the attached solution, as much help as possible please as i am lost. The problem does not specify, what valves are a hazardous system, it is a closed system that serves no purpose as far as i can see. I have not studied any thermofluid systems as yet, it seems too much of a jump in kno ...continues
