1)The power that can be extracted from an airstream is proportional to: 
  

2)If the wind Energy Density Density of an airstream is 650 Watts/meter2 and the air density is 1 kg/m3, then what is the wind velocity? 
  

3)If the wind speed is 12 m/s and the air density is 1.2929 kg/m3, what is the wind energy density? 
  

4)The Betz limit, the theoretical limit to the maximum amount of power that can be extracted from an airstream is: 
  

5)A place where many wind turbines are installed together to produce electricity is called a
