You need to construct a 400 pF capacitor for a science project. You plan to cut two L×L metal squares and place spacers between them. The thinnest spacers you have are 0.20 mm thick. What is the proper value of L?

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.

Ithink the answer is d
