Answer:
[tex]1\times 10^{-9}\ m=1\ nm/s[/tex]
Explanation:
The continental drift speed is, [tex]v=10^{-9}\ m[/tex]
The options have some prefix. These are as follows :
1. Tera (T) = [tex]10^{12}[/tex]
2. Giga (G) = [tex]10^{9}[/tex]
3. Nano (n) = [tex]10^{-9}[/tex]
4. Pico (p) = [tex]10^{-12}[/tex]
The speed of continental drift is equivalent to 1 nm/s. So, the correct option is (c).
