Final answer:
To determine how many years it would take to supply a certain amount of energy using the energy output of 1,400 MW from an electricity generating plant, we need to divide the desired amount of energy by the rate of electricity generation.
Step-by-step explanation:
To determine how many years it would take to supply a certain amount of energy using the energy output of 1,400 MW from an electricity generating plant, we need to convert 1,400 MW to the unit of energy (Joules) and then divide the desired amount of energy by the rate of electricity generation.
Assuming each year has approximately 3.16x107 seconds, the energy output from a 1,400 MW plant in one year would be 1.07x107 Joules. Dividing the desired amount of energy by the rate of electricity generation gives us the number of years it would take.
Therefore, the correct answer is a. 51.6 years.
