Question

what is parsec and angstrom​

Answer 1

Answer:

Parsec is defined as the distance that one astronomical unit subtends an angle of one arc second. Therefore, it is a unit of distance. It is obtained by the use of parallax and trigonometry

The angstrom or ångström 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..
