Options

  1. A10 - 6   mm
  2. B10 - 7   mm
  3. C10 - 8   mm
  4. D10 - 9   mm

Correct answer

B. 10 - 7   mm

Step-by-step solution

The angstrom or angstrom is a metric unit of length equal to 10 - 10   m ; that is, one ten-billionth of a metre, 0 . 1 nanometre, or 100 picometres. Its symbol is Å , a letter of the Swedish alphabet. The angstrom is not a part of the SI system of units, but it can be considered part of the metric system in general.
