A steel cable supports a lift that can carry a maximum load of 1600Kg and it moves with an acceleration (a). (Young modulus of steel (Y)=3x1011 N/m2. Proportional limit stress =2x1010N/m2). Determine whether the maximum tension in the cable occurs as the lift is ascending or descending. And if this maximum tensile force is 25 KN, determine the value of the acceleration (a)?

Not what goes around on earth but the universe too.

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.
