Aphysicist found that a force of 0.68 n was measured between two charged spheres. the distance between the spheres was 1.0m. calculate the force between two spheres when the distance between the spheres was decreased by .50m.

The answer would be  0.40m. you are finding how far the distance is between 10 and 50

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.
