A single-phase ac voltage of 240 V is applied to a series circuit whose impedance is 10 60degree ohm ft. Find R, X, P, Q and the power factor of the circuit. lf a capacitor is connected in parallel with the circuit of Prob. 1.4, and if this capacitor supplies 1250 var, find the P and Q supplied by the 240-V source, and find the resultant power factor.

The answer is  a.first and third quarters 

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.
