using the amplitude and energy relationship\naverage amplitude of waves from 2009 to 2011\na structural engineer is using this table to design a wall to protect a city near the ocean. how high should the engineer build the wall?\n50 meters\n100 meters\n150 meters\n200 meters

Answer

Explanation:

Step1: Analyze the graph

The highest average - amplitude value from 2009 - 2012 is 175 meters (approx. peak value in 2010). To ensure the wall can protect the city from the waves, the engineer should build the wall at a height that can withstand the maximum wave amplitude observed in the given period.

Step2: Select the appropriate option

Among the given options, 200 meters is the height that is greater than the maximum observed average - amplitude and will provide sufficient protection.

Answer:

200 meters
