Two electrons move side by side with the same velocity as shown in the figure here. At what speed v will each experience zero
net force given the frame of reference implied in the figure? Ignore
electromagnetic induction, and if you are familiar with Special
Relativity, you may ignore it for this question as well

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
