Question

length cannot be measured by : (A) fermi (B) debye (C) micron (D) light year

Answer 1

 (B) debye
------------------------------------------------
Length cannot be measured by debye

it is the unit used to measure electric dipole moments of molecules

Answer 2

Answer:

The correct answer will be -

(B) Debye

Explanation:

By checking the options -

(A) fermi - It can be used to measure the length. Also, $10^{15$ fermimeter is equal to 1 meter.

(B) Debye - It cannot be used to measure the length. Debye is used to measure the dipole moment.

(C) Micron - It can be used to measure the length. Also, $10^6$ micrometer is equal to the 1-meter length.

(D) Light year - It can be used to measure the distance. Used to measure large distances, such as the distance between two stars. It is equal to the distance traveled by the light in a year.
