|Total impedance= R-JXc.|

|Please Given the explanation.|

Now resistance and frequency is halved so R become R/2 and Xc=1/2π(f/2)c => 2Xc=1/2πfc.
Z'=R/2+ 2Xc so impedance neither double nor halved. So, It cannot determine without values.

|There is no explanation about capacitance so without value of capacitance we can't say anything.|

|z =√((2R)^2+(2/wC)^2) because resistance is double and frequency is half.
z = 2√((2R)^2+(2/wC)^2).
So the impedence is double.
