Question 1) Suppose a household used 1.65 X 10^4 kW of electricity in one year. This electricity came from a traditional coal-fired generating station. Based on the diagram attached, what mass of carbon dioxide gas was emitted to produce the household's electricity?A. 2.3 X 10^2 kgB. 1.7 X 10^4 kgC. 8.2 X 10^3 kgD. 1.3 X 10^4 kgRemaining questions are true or false. Question 2) The output voltage in a step-up transformer is greater than the input voltage. Question 3) The joule is a unit of energy.Question 4) The kilo-watt hour is a unit of power.Question 5) The output of a transformer comes off the primary coil. Question 6) The watt is a unit of power.Question 7) When the magnitude of the current through a resistor increases, the power consumed by the resistor increases.
