Try deducing Torriccelli's formula from the equations for position and velocity with respect to time:
2 = xo + vot + at
I
1
U = V0 + at.
Remember that the displacement is defined as the variation in the position
d=1 - 10
Hint:Remember that (a + b)2 = a² + 2ab + 62.
2

Ithink it is c ,i hope i you

Sorry i don’t know what to do

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.
