What would you expect to happen to the acceleration if all friction were removed from the ramp, making the net force even higher than 600 n?

You will hear a hissing sound because of the carbon dioxide escaping the can or bottle

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.
