Maxine, a physics lecturer, assigns her students a five-page-long assignment on the theory of relativity that needs to be submitted in two days. Only 40% of the class completes the assignment within the specified time. Noticing the delay in submission, Maxine tries to convince her students in a different way. She tells them that though the assignment involves extensive research and is difficult to complete within a short time, it is important as the scores obtained will be added to their physics theory scores. The next day, almost 70% of the class turns up with their assignments. In the context of persuasion, this scenario illustrates:

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 of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
