A three-phase Y-connected source is energizing a Δ-connected load. The phase voltage of the transmission line is = 120∠0 ∘, and the load impedance is ∆ = 9∠30∘Ω. Compute and the power consumed by the load.

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.
