i have no idea that is why I came to this website

2,000,000 is the answer. This is because one millimeter equals 1,000,000 nanometers, and if you have two millimeters you would multiply 1,000,000 by 2 which is 2,000,000.

To calculate the number of nanometers, you need to convert millimeters to nanometers. Here is how you can do it:

1 millimeter (mm) = 1,000,000 nanometers (nm)

First, we know that a nickel is about 2 millimeters thick. So, we can multiply 2 by 1,000,000 to convert it to nanometers:

2 millimeters * 1,000,000 nanometers/millimeter = 2,000,000 nanometers

Therefore, a nickel is approximately 2,000,000 nanometers thick.
