What victim mentality, neuroticism and psychoticism have in common is a relatively high frequency of negative emotional states such as anger, sadness, and fear.ut these three traits are also partially independent: for example a given individual may have a high degree of victim mentality and a low degree of neuroticism, in which case a clinical psychologist is unlikely to regard her or him as needing treatment.
An anemometer is a device that tells you how fast the wind is blowing. The device you can build is a model of a wind speed indicator. A real one will be able to accurately measure how fast the wind is blowing. Yours will give you only approximation of how fast it's blowing.
Wind has both speed and direction. Anemometers measure wind speed and wind vanes measure wind direction. A typical wind vane has a pointer in front and fins in back. When the wind is blowing, the wind vane points into the wind. For example, in a north wind, the wind vane points northward. A cup anemometer is a common tool to measure wind speed. The cups catch the wind and produce pressure difference inside and outside the cup. The pressure difference, along with the force of the wind, causes the cups to rotate.
