Answer 1

ANSWER:

Wind vane

A wind vane is used as part of the anemometer to determine the wind's direction. As the wind flows over the windmill, the speed and direction of the wind can be measured with this instrument. Some scientific anemometers use the speed of sound to measure the wind speed more precisely in three dimensions.
