Which of the following is the best conclusion concerning why the cathode rays in experiment 1 had a mass to charge ratio 1,000 times smaller than that of any known atom?Explain why u chose this answer

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)
