Since what are in parallel?

Q1) What purpose does the series resistor serve in a simple zener-based regulator?

Q2) What is the purpose/meaning of the voltage at the negative input of the op-amp?

Q3) What would happen if the Rv resistor were removed (open circuit)?

Q4) What would happen if the Rv resistor were shorted?
