You are sitting in a chair on an elavator. The elavator accelerates downward, you and the chair land on the cround with the chair landing first and then you on the chair. Explain the Net Forces at 3 points for each object

The points are: Before the Elevator Accelerates Downward, In Freefall, At Impact

Analyze whether the Normal Force would need to increase, and where the direction of the net force is for each object.

You will hear a hissing sound because of the carbon dioxide escaping the can or bottle

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.

Ithink the answer would be a
