The noninverting amplifier in Figure P14.13 has an op-amp with open-loop properties: \(A_{O L}=10^{3}, R_{i}=20 \mathrm{k} \Omega\), and \(R_{o}=0.5 \mathrm{k} \Omega\).

(a) Determine the closed-loop values of \(A_{C L}=v_{O} / v_{I}, R_{i f}\), and \(R_{o f}\).

(b) If \(A_{O L}\) decreases by 10 percent, determine the percentage change in \(A_{C L}\).
