Question

The virus that causes the flu has a width of 130 nanometers.A nanometer is 0.00000001 m write the width of the flu virus in scientific notation

Answer 1

`1.3 * 10^(-6)m`

Explanation:

Givens

• The width of the virus is 130 nanometers.
• A nanometer equals 0.00000001 m.

So, first we multiply the width of the virus and the nanometers

`130nm* (0.00000001m)/(1nm) =0.0000013m`

Now we have the width in meters, we express the number in scientific notation.

To do that, we must move the decimal point 6 spots to the right, then we express that as a power which base is 10 and its exponent 6 (the number of spots we moved)

`1.3 * 10^(-6)m`

Therefore, the scientific notation is
`1.3 * 10^(-6)m`

Answer 2

Answer: The answer is 1,3 x 10-7 meters.

Explanation:

The nanometer unit is a measure of length. The prefix nano refers to 9, in this case 10 ^ -9. That is, 130 nm = 130x 10 ^ -9 m equals 1.3 x10 -7 meters.
