A Philips XL-30 model (The Netherlands) scanning electron microscope was used to measure the diameter of particles produced by the spray dryer.
Let's say the ruler can find the measurement to the nearest.1 cm -- this does not mean that you can measure the diameter to this level of precision.
Attempts have even been made to measure the diameter of the net (see below).
The probe was used to measure the diameter and the roundness of micro-scale holes.
After several estimates have been suggested, take a long piece of string and with one end measure the diameter of the Earth.
We also marked a certain height on the tree with red paint, so staff can go back in and measure the diameter of the trunks for research projects.
According to this discovery, our approach is designed to measure the diameter of crystal in two stages.
In this paper, a novel approach based on concentric ellipses is proposed to measure the diameter of silicon single crystal.
An array of laser-based infrared telescopes he built at the Mount Wilson observatory outside Los Angeles can measure the diameter of stars that appear as mere points of light in most telescopes.
If you want to compare the results from your experiment to something else, I tell you how to build a very simple instrument that will enable you to measure the diameter of both the Moon and the Sun.
To me, the sweet little woolly-bear traversing my hand was a "calipitter". It was only years later I learned that a calipitter is an instrument used to measure the diameter of a caterpillar to the nearest micron.
