Unit Length
kilometer (km) 1,000 m (1 X 10^3 m)
meter (m) 1 m
centimeter (cm) 0.01 m (1 X 10^-2 m)
millimeter (mm) 0.001 m (1 X 10^-3 m)
micrometer (um) 0.000001 m (1 X 10^-6 m)
nanometer (nm) 0.000000001 m (1 X 10^-9 m)
Indicate your specific subject in the "School Subject" box, so those with expertise in the area will respond to the question.
To determine the correct size order, we need to compare the different units of measurement and arrange them in ascending order based on their magnitudes.
First, let's familiarize ourselves with the units mentioned:
- nm: nanometer
- um: micrometer
- mm: millimeter
- cm: centimeter
- m: meter
Now, we can compare them to find the correct size order:
Starting with the smallest unit, we have:
1 nanometer (nm) is smaller than 1 micrometer (um).
Then, comparing micrometers with millimeters:
1 micrometer (um) is smaller than 1 millimeter (mm).
Next, comparing millimeters with centimeters:
1 millimeter (mm) is smaller than 1 centimeter (cm).
Lastly, comparing centimeters with meters:
1 centimeter (cm) is smaller than 1 meter (m).
Based on the comparisons, we can conclude that the correct size order is:
a) nm, um, cm, mm, m
Therefore, option (a) is in the correct size order.
