A 1250-kg sports car (including the driver) crosses the rounded top of a hill (radius = 89.0 m ) at 23.0 m/s . Determine the normal force exerted by the road on the car.
Determine the normal force exerted by the car on the 70.0-kg driver.

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.
