We live on our mild climate in oblivious serenity with our nearly circular stable orbit while in another universe, the force of gravity is instead F(r) = −k/r3 . Calculate the effective potential energy and characterize stability for possible orbits with a variety of energy & angular momentum initial conditions (ie pφ less than, equal to, and greater than µk). Calculate the orbit shapes for each of these conditions.

Wish i knew this to !

The rocks expand when there hot/warm  and contract when they are cold.

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.
