A roller coaster loop has a frequency of .88 Hz. The loop has a radius of 11.932 m. The coaster has a mass of 543 kg. Find the velocity of the loop
and then find the Fn of the roller coaster at the top of the loop.

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.
