A 3.8 T magnetic field suspends a 0.3 m of copper wire with a current of 2 A in the air. What is the mass of the wire? Round answer to two decimals

10 neutrons is the answer

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.
