Question

The diameter of a proton is 1.7 x 10-15 meters and the diameter of an atom is 5 x 10-10 meters. What is the difference in the diameters? Write your answer in scientific notation.

Answer 1

`4.99* 10^(-10)\ m`

Explanation:

Given that,

The diameter of a proton is 1.7 x 10⁻¹⁵ meters

The diameter of an atom is 5 x 10⁻¹⁰ meters.

We need to find the difference in the diameters.

`D=5\cdot10^(-10)-1.7\cdot10^(-15)\\\\=4.99* 10^(-10)\ m`

So, the difference in the diameter is
`4.99* 10^(-10)\ m`.
