Calipers measure the internal or external dimensions of something.
A micrometer is a common instrument used to measure the external and internal diameter of a test tube. It is a precision tool that provides accurate measurements of small distances. Another option is a caliper, which can also be used for measuring diameters.
A thermometer
There is no single instrument for either of these things
A vernier caliper
Thermometer is the instrument used to measure average thermal energy.
A set of calipers.
Vernier caliper
A manometer instrument is used to check the alignment of two shafts.
The instrument used to measure the diameter of spherical objects is called calipers.
A Vernier caliper, or a micrometer can measure diameter real well, and from that it's easy to calculate area.
A vernier caliper or a micrometer can be used to measure the internal diameter of a beaker. These tools provide accurate measurements of dimensions, including internal diameters, with precision.
Astronomers use a variety of instruments such as telescopes and radar to measure the diameter of planets. One commonly used instrument is a laser range finder, which can be used to determine the size of a planet by measuring the time it takes for a laser beam to bounce back to Earth after being pointed at the planet's surface.
No. The instrument used to measure wind speed is an anemometer.
The instrument which is used to measure snowfall is called a snow gauge.
