Which of the following curves represents the variation of impedence (Z) with frequency f in series LCR circuit?

Show graphically the variation of X_L with frequency f.

The figure shows variation of R,X_(L) and X_(C) with frequency f in a series L,C,R circuit. Then for what frequency point, the circuit is inductive ?

Which of the following graphs represent the variation of current(I) with frequency (f) in an AC circuit containing a pure capacitor?

A source of sound emits sound waves at frequency f_(0) . It is moving towards an observer with fixed speed v_(s)(v_(s) lt v where v is the speed in air). If the observer were to move towards the source with speed v_(0) one of the following two graphs (A and B) will give the correct variation of the frequency f heard by the observer as v_(0) is changed, The variation of f with v_(0) is given correctly by :-
