Question

pick out the odd one of the following (1) fermi (2) angstrom (3) nanometre (4)light year​

Answer 1

Answer:

(2) angstrom

Explanation:

Answer 2

Answer:

The correct answer is option D

Explanation:

The odd one among the given four options:

• fermi
• angstrom
• nanometre
• light year

Is Light year.

All the given options are units to measure length.

While fermi, angstrom and nanometer are smaller units to measure length, a light-year is a comparatively much larger unit.

• A light-year is used to measure astronomical distances. When light travels some distance in one year at its characteristic speed that distance is said to be one light year.
• One light-year is approximately equal to 9.5 trillion kilometres.
• Fermi is the SI unit of length used to measure distances in sub-atomic particles.
• One fermi is equal to the quadrillionth of metres.
• Similarly, angstrom and nanometer are also smaller units of distance and are used to measure very minute substances.

1. 1 fermi = 10⁻¹⁵ m
2. 1 angstrom = 10⁻¹⁰m
3. 1 nanometer= 10⁻⁹m
