A 400-kg roller coaster cart reaches point B with a speed of 35 m/s. How fast was is traveling when it was at point A?

The sample with the lowest specific heat capacity will have the greatest temperature increase. in this case, it would be platinum.

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.
