Which describes the electric field on the central axis through a ring of uniform negative charge the field vectors point along the axis and away from the ring on both sides of the ring. the field vectors point along the axis and toward the ring on both sides of the ring. the field vectors point along the axis and away from the ring on one side of the ring and toward the ring on the opposite side.

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 (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
