A pachymeter is any of a group of instruments which are used to measure the thickness of something.
The answer is e.g rain gaige/ windvane/ barometer/ windmill e.t.c
These days with GPS. They used to use an altimeter, or geometry (lines of sight from known locations (typical surveyor's work)).
The first variable that is used to classify stars is its ionization state which can measure the photosphere's temperature and density. This information is gathered by splitting the light from a star with a prism and observing the resulting spectrum that includes absorption lines. Luminosity is another variable used; it is based on the width of absorption lines.
At first they will use the twine to measure the curved lines and then they will take one scale and looke the measure
A jigsaw is used for cutting curved or round holes. With a straight guide it can cut straight lines.
The method used to measure lines of longitude and latitude to determine exact location is called geodetic surveying. It involves the use of specialized instruments such as theodolites and GPS receivers to accurately measure angles and distances on the Earth's surface. These measurements are then used to calculate the precise coordinates of a particular location.
They are surveying instruments used to measure angles.
Some test instruments used in electronics are:Multimeter - Used to measure voltage, ampere and resistanceOscilloscope - Used to measure frequency and oscillations
The instruments used to measure the conditions of the upper atmosphere is a Radiosonde, Radar, Weather Satellites, and Computers.
A ruler, a yard stick, and a tape measure can each be used to measure length. There are other instruments, but these are probably the most common.
To measure various physical quantities, different instruments are used based on the type of quantity being measured. Here are some examples: Length: Measured in meters (m). Instruments used to measure length include rulers, tape measures, and calipers. Mass: Measured in kilograms (kg). Instruments used to measure mass include balances and scales. Time: Measured in seconds (s). Instruments used to measure time include clocks and stopwatches. Temperature: Measured in degrees Celsius (°C) or degrees Fahrenheit (°F). Instruments used to measure temperature include thermometers. Electric current: Measured in amperes (A). Instruments used to measure electric current include ammeters. Voltage: Measured in volts (V). Instruments used to measure voltage include voltmeters. Frequency: Measured in hertz (Hz). Instruments used to measure frequency include oscilloscopes and frequency counters. Pressure: Measured in pascals (Pa). Instruments used to measure pressure include barometers and manometers. There are many other physical quantities that can be measured, and different instruments may be used depending on the specific quantity and the required precision of the measurement.
