Question

An angstrom is about the size of an atom and a fermi is about the size of the nucleus of an atom. Given that 1 angstrom unit = 10⁻¹⁰ m and 1 fermi = 10⁻¹⁵ m, what is the relationship between these units?

Answer 1

Answer:

See explanation below

Explanation:

To do this, we need the relation between a fermi and angstrom. We know the relation between the angstrom and meters, and fermi and meters, so, we can actually solve this by doing the conversion of meters.

1 A = 1x10^-10 m

1 m = 1 A / 1x10^-10 m

1 m = 1x10^10 A

Now if we do the same thing with the fermi:

1 f = 1x10^-15 m

1 m = 1 f / 1x10^-15 m

1 m = 1x10^15 f

then:

1x10^10 A = 1x10^15 f

A/f = 1x10^10 / 1x10^15

A/f = 1x10^-5
