• Part A Estimate how many large maple trees would be needed to run a dishwasher for one year. Assume the dishwasher uses 1.1 x10° J of energy per year and a large maple tree captures 10 kg of carbon (in CO2) per year. Assume the power plant that generates the electricity is 31 % efficient at converting the carbon in coal to electrical energy and that typical coal releases 40,000 kg of carbon (as CO2) per terajoule of energy when burned. Express your answer using two significant figures. ? n= 1.29 trees/year Submit Previous Answers Request Answer X Incorrect; Try Again; One attempt remaining < Return to Assignment Provide Feedback
