The contrabassoon is the wind instrument capable of sounding the lowest pitch in an orchestra. it is folded over several times to fit its impressive 18 ft length into a reasonable size instrument. the actual fundamental frequency of the contrabassoon is 27.5 hz , which should be different from your answer in part a. this means the model of the instrument as an open-closed tube is a bit too simple. but if you insist on using that model, what is the "effective length" of the instrument?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
