Which statement best describes a difference between the trachea and the esophagus?
The trachea is a long, hollow tube, and the esophagus is a small, kidney-shaped organ
The trachea is part of the digestive system, and the esophagus is part of the respiratory system
The trachea delivers oxygen through the body, and the esophagus releases carbon dioxide
The trachea allows for the passage of air, and the esophagus allows for the passage of food

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
