could use some help thanks

In an RLC series circuit, the voltage amplitude and frequency of the source are 100 V and 500 Hz, respectively, and R = 550 Q, L = 0.29 H, and C=2.1yF (a) What is the impedance of the circuit (in Q)? ( Jxo (b) What is the amplitude of the current from the source (in A)? C x s (c) If the emf of the source is given by v(t) = (100 V)sin(1,000xt), how does the current vary with time? (Use the following as necessary: t. Assume i(t) is in amps and t is in seconds. Do not include units in your answer.) i(t) = (d) Repeat the calculations with C changed to 0.21 pF.
