A. The weight of feral pigs depends on the quality of the habitat but generally adult males range up to 115 kilograms and sows 75 kilograms. In some cooler and wetter areas feral pigs can grow very large with a 175 kilogram boar caught just south of Canberra while boars over 200 kilograms are regularly caught in New Zealand.
Large modern wind turbines have rotor diametres ranging up to 65 metres while smaller machines (around 30 metres) are typical in developing countries. Towers range from 25 to 80 metres in height.
