An angstrom (symbol A) is a unit of length, defined as 10^-10, which is on the order of the diameter of an atom.
Part A: How many nanometers are in 3.5 ?
Part B How many femtometers or fermis (the common unit of length in nuclear physics) are in 3.5 A?
Part C How many angstroms are in 5.5 meter?
Part D How many angstroms are in 5.5 light-year?
