The smallest unit of length is nanometers Na: the abbreviation n is the abbreviation of nano, which is a unit of magnitude in English. It refers to 10 ^ (- 9), that is, one ninth power of 10. Therefore, nano is "one ninth power of 10" of 1 meter, that is, one billionth of a meter. But this is not the smallest unit of length at all

Unit of measurement conversion
Frequency 100GHz equals ()
A105MHz B 1011Hz C 100kMHz
D 10^-1THz E 105mHz
The answer is abd,

1G=1000M=1000 000K=10^9
M=10^6
K=10^3
So 100g = 10 ^ 11
And 100km = 100 * 10 ^ 3 * 10 ^ 6 = 10 ^ 11
So choose C
