A flat, wide cloud floats horizontally a few kilometers above the surface of Earth. Its lower surface carries a uniform surface charge density of -2.6Ă10-4 C/m2 , while there is no excess charge elsewhere in the cloud. What is the magnitude of the electric field, in newtons per coulomb, a few meters below the cloud, under the cloudâs approximate center, due to the charge distribution?

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 1.00Âşc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in Ă10^{-3} â3 m)
