QUESTION: 2

1 fermi is equal to:

Solution:

The fermi is a unit of measurement of length

The metric unit prefix femto means one quadrillionth, or one (1) with fourteen (14) nulls in front of it, i.e. 0.000,000,000,000,001 or 1×10-15. That makes one femtometer (and one fermiequal to one quadrillionth of a meter.
