Adock worker loading crates on a ship finds that a 27 kg crate, initially at rest on a horizontal surface, requires a 80 n horizontal force to set it in motion. however, after the crate is in motion, a horizontal force of 56 n is required to keep it moving with a constant speed. the acceleration of gravity is 9.8 m/s 2 . find the coefficient of static friction between crate and floor.

26.4 is about the right time

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.
