A low-mass rod of length 0.30 m has a metal ball of mass 1.8 kg at each end. The center of the rod is located at the origin, and the rod rotates in the yz plane about its center. The rod rotates clockwise around its axis when viewed from a point on the +x axis, looking toward the origin. The rod makes one complete rotation every 0.6 s. What is the moment of inertia of the object (rod plus two balls)?

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)
