Consider earth and the moon. as you should now realize, thegravitational force that earth exerts on the moon is equal andopposite to that which the moon exerts on earth. therefore, according to newton’s second law of motion
check the right answer
1)the moon has a larger acceleration than earth, because it has asmaller mass
2)earth has a larger acceleration than the moon, because it has alarger mass
3)the moon and earth both have equal accelerations, because theforces are equal

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
