Two pots are identical except that the flat bottom of one is aluminum, whereas that of the other is copper. water in these pots is boiling away at 100.0 ˚c at the same rate. the temperature of the heating element on which the aluminum bottom is sitting is 161 ˚c. assume that heat enters the water only through the bottoms of the pots and find the temperature of the heating element on which the copper bottom rests.

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
