The instrument commonly used to measure the gases in stars is called a spectrometer. This device analyzes the light emitted or absorbed by a star, breaking it down into its constituent wavelengths. By examining the resulting spectrum, astronomers can identify the chemical elements present and their abundance, as well as gauge the star's temperature, density, and motion.
Manometer
An instrument used to measure stars is called a spectrometer. It analyzes the light emitted or absorbed by stars, allowing astronomers to determine their composition, temperature, distance, and velocity. Another important tool is the telescope, which magnifies distant celestial objects, enabling precise observations and measurements of stars’ positions and brightness. Together, these instruments enhance our understanding of the universe.
The barometer is the instrument that is used to measure the air pressure.
One instrument used to measure roughness of roads is the response type road roughness meters (RTRRMs)
This instrument is an adequate type of balance.
An aerometer is an instrument used to measure the mass and density of gases.
Manometer
A cross staff is a navigational instrument used to measure angles, typically for celestial navigation, by aligning a crosspiece with an object in the sky. An astrolabe is a historical instrument used to observe and measure the positions of stars and planets. It was used for navigation, timekeeping, and astrology.
No. The instrument used to measure wind speed is an anemometer.
The instrument which is used to measure snowfall is called a snow gauge.
A thermometer
There is no single instrument for either of these things
The instrument used to measure humidity is called a hygrometer.
The instrument used to measure humidity is called a hygrometer.
Astral navigation. By using a sextant (instrument used to measure the altitude of a celestial object) a clock and logarithms you can work out your position on the earth's surface hence 'sailing by the stars'
A protractor is used to measure an angle.
A protractor can be used to measure an angle.
