The water content of moist air can be measured with no less than six different metrics: Wet Bulb Temperature, Relative Humidity, Absolute Humidity, Degree of Saturation, Humidity Ratio (also known as Mixing Ratio), and Specific Humidity.
You can use a sextant to determine the position (called the âshootâ) in the sky of the sun, moon, or other celestial body, as well as your longitude. Although its design looks complicated, with an understanding of how it works and practice, you can reliably use it to find your position. Ad.
A potentiometer (or pot) is an electrical device used to measure angular position. The user can therefore adjust the degree to which the potentiometer opposes electric current through it, simply by turning a shaft that is attached to the center of the potentiometer. As the resistance of the potentiometer changes, so does the voltage, which thus causes the potentiometer to act as a variable voltage divider. This varying voltage can be measured by the VEX microcontroller and is directly proportional to the angular position of the shaft connected to the center of the potentiometer.
