g A block of mass 0.42 kilogram is initially at rest at the top of a frictionless ramp that has a surface length of 1.3 meters and is inclined by 12 degrees above horizontal. The block slides down and impacts a spring with spring constant k, causing the spring to compress by 0.41 meters when the block comes to a rest. What is the value of the spring constant in units of Newton/meter

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.

This question is incomplete and not physics but i'm  willing to if you can give a better question

Hello,the answers iron,  hope this

Answer a, i don't feel like going into detail on this one because of how long that read was. water goes whoosh moving through the turbines to turn them and convert the energy of these mechanisms into electrical energy :
