A 1800 kg crate and a level floor has a coefficient of static friction of 0.75 and a coefficient of kinetic friction of 0.67. a. How hard can you push the crate until it starts moving?

b. Find the acceleration of the crate if someone pulls horizontally on the crate with a force of 20,000.

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.
