Two conducting rods are made of the same material and have the same length. conductor b has a diameter twice that of conductor a but is hollow with an inner diameter of conductor a.
1. what is the resistance ratio ra/rb, measured between their ends?
2. if the temperature of a rod changes by 1.0 °c, what percentage changes in r, l, and a will occur?
3. what conclusion do you draw?

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
