Abasket of negligible weight hangs from a vertical spring scale of force constant 1500 n/m. if you suddenly put a 3.00 kg adobe brick in the basket, find the maximum distance that the spring will stretch. 3.92 cmif, instead, you release the brick from 1.00 m above the basket, by how much will the spring stretch at its maximum elongation?

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)

Sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) attraction that bonds them together.
