A capacitor is connected across an ac source that has voltage amplitude $68\mathrm{.}5$ VV and frequency $77\mathrm{.}5$ HzHz $.$ Part A

What is the phase angle $$ for the source voltage relative to the current?

Express your answer in degrees. Part C

What is the capacitance CC of the capacitor if the current amplitude is $5\mathrm{.}60$ AA $?$
