Assuming its "resting" is the place in the middle of the wave crest and trough, the distance between the crest and the middle line would be considered its amplitude. The height of a wave is the distance between the crest and the trough, and wavelength is the distance between two crests.

Biomass is the most used renewable source of energy in US in the year of 2009.
<h3><u>
Explanation:</u></h3>
In US, the country is very cold and use of wood and other plant products as chimney fuels, or in cooking and other purposes are very common. This is because being a temperate country, US has forests of conifers which are source of soft wood, ideal for burning.
