The rate of conductive heat loss through a single-paned window that measures 50 cm by 80 cm is 123 W. A second window, right next to the first, measures 40 cm by 50 cm, and its glass pane has the same thickness as the first window. How long does it take 1,906 J to leak across this second widow

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
