Two objects a and b of same masses and velocities v and 3v respectively are in motion . which object of larger momentum

P=mv and A , B have same masses(name it m)
So A’s momentum=mv=mv
B’s momentum=mv=3mv
3mv>mv so B has a larger momentum. Hope this helps.

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.
