When two or more capacitors are connected in series across a potential difference

A) the equivalent capacitance of the combination is less than the capacitance of any of the capacitors.
B) the potential difference across the combination is the algebraic sum of the potential differences across the individual capacitors.
C) each capacitor carries the same amount of charge.
D) All of the above choices are correct.
E) None of the above choices are correct.

Question 2

A string 40.0 cm long of mass 8.50 g is fixed at both ends and is under a tension of 425 N. When this string is vibrating in its third OVERTONE, you observe that it causes a nearby pipe, open at both ends, to resonate in its third HARMONIC.

The speed of sound in the room is 344 m/s.
(a) How long is the pipe?
(b) What is the fundamental frequency of the pipe?
