Ahydrogen atom has a diameter of about 10 nm. express this diameter in micrometers, meters, and millimeters.

A diameter of A hydrogen atom 10 nm in micrometers, meters, and millimeters :  10⁻²  μm, 10⁻⁸  m,10⁻⁵ mm

Magnitude is something that can be measured or counted

The principal amount is the amount that has been determined based on the agreement of the scientists

Derivative magnitude is a quantity derived from the principal amount

There are 7 main quantities that have been determined based on international standards, namely:

The length of the principal is to indicate the distance between two points in a place

The symbol is usually expressed in l, length

Length measurement can be used by several measuring instruments such as ruler, caliper length, meter, screw micrometer

The main length unit consists of 7 units other than other units of length such as inches, miles, yards, feet:

Each one unit descends then multiplied by 10, and if one unit increases then divided by 10

Conversion of other mass units:  

mm millimeters = 10⁻³ m

km kilometers = 10³ m

µm micrometers (mcm) = 10⁻⁶ m  

nm nanometers = 10⁻⁹ m  

Gm gigameters = 10⁹ m  

ρm picometers = 10⁻¹² m

A hydrogen atom has a diameter of about 10 nm

So in micrometers µm = 10⁻⁹ /10⁻⁶ .10= 10⁻²

meters = 10⁻⁹ m . 10 = 10⁻⁸

and millimeters = 10⁻⁹ /10⁻³ . 10 = 10⁻⁵

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
