Answer:
(1) 10^−2 m
Explanation:
The diameter of the tire of an automobile is generally expressed in centimetres; we can say that the diameter of a tire is generally about
d = 20 cm (20 centimetres)
Now we have to verify which option is closest to this value. To do that, we have to keep in mind the equivalence between metres and centimetres; in fact, we have:
[tex]1 cm = 10^{-2} m[/tex]
This means that we can rewrite the diameter of the tire of a car as
[tex]d=20 cm = 20\cdot 10^{-2} m[/tex]
By comparing it with the given options, we see that the closest option is
(1) 10^−2 m
which is therefore the correct answer.
