A 40 % efficient machine operates with an input force of 3000N. what is the output force if ima is 8​

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).

This is the answer of your question

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.
