In a certain experiment, it was necessary to be able to move a small radioactive source at selected, extremely slow speeds. This was accomplished by fastening the source to one end of an aluminium rod and heating the central section of the rod in a controlled way. If the effective heated section of the rod in fig. 21- 18 is 1.8 cm, at what constant rate must the temperature of the rod be made to change3 if the source is to move at a constant speed of 96 nm/s?
