A 1500-WW electric heater is plugged into the outlet of a 120-VV circuit that has a 20-AA circuit breaker. You plug an electric hair dryer into the same outlet. The hair dryer has power settings of 600 WW, 900 WW, 1200 WW, and 1500 WW. You start with the hair dryer on the 600-WW setting and increase the power setting until the circuit breaker trips.?

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.
