Detailed explanation-1: -Regular tools like scissors are too big!
Detailed explanation-2: -A human hair is approximately 80, 000-100, 000 nanometers wide. A single gold atom is about a third of a nanometer in diameter.
Detailed explanation-3: -In the International System of Units, the prefix “nano” means one-billionth, or 10-9; therefore, one nanometer is one-billionth of a meter. It’s difficult to imagine just how small that is, so here are some examples: A sheet of paper is about 100, 000 nanometers thick.
Detailed explanation-4: -3. Can macro scale objects, like scissors, be used on the nanoscale? No, macro scale objects cannot be used on the nanosclae, becasue the nanoscale is way too small for macro scale objects to cut down to.
Detailed explanation-5: -The nanoscopic scale (or nanoscale) usually refers to structures with a length scale applicable to nanotechnology, usually cited as 1–100 nanometers (nm). A nanometer is a billionth of a meter. The nanoscopic scale is (roughly speaking) a lower bound to the mesoscopic scale for most solids.
