a marble rolls off a table with a speed of 2.30 m/s. if the table is 1.12 m high, how far from the
base of the table does the marble land? (find the time in the air first.)

The magnets would be | n s | and | s n|

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
