neutron is 0.0000000000017 millimeters in size. Express this number in scientific notation.

Question

x 10

Answer 1

To express the size of a neutron, which is given as $0.0000000000017$ millimeters, in scientific notation, we can rewrite it as follows:

1. Move the decimal point to the right until we have a number between 1 and 10. For $0.0000000000017$, we move the decimal point 12 places to the right, which gives us $1.7$.
2. Since we moved the decimal 12 places to the right, we multiply by ${10}^{-12}$.

Therefore, in scientific notation, the size of a neutron is:

$$1.7\times {10}^{-12}\text{ millimeters}$$
