A group of students conducted an experiment to find out what happens to the force of magnetism between two magnets as the distance between them increases. They used the equipment you see in the illustration. They placed spacers between the magnet in the cup and the magnet on the post to increase the distance between them. They used washers as units to measure how much force it took to pull the two magnets apart.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
