Worked Solution & Example Answer:Figure 13 shows a large wind farm off the coast of the UK - AQA - GCSE Physics - Question 9 - 2022 - Paper 1
Step 1
Calculate the Mean Power Needed for 1 Home
Answer
To calculate the mean power needed for 1 home, we start with the total mean power output of the wind farm, which is 696 MW.
-
Convert megawatts to watts:
696 ext{ MW} = 696 imes 10^6 ext{ W} = 696,000,000 ext{ W}
-
Divide the total power output by the number of homes:
ext{Mean power needed for 1 home} = \frac{696,000,000 ext{ W}}{580,000} ext{ homes} = 1200 ext{ W}
Therefore, the mean power needed for 1 home is 1200 W.
