The length of the copper in meters is 1.6 times 10^-2 meters.
According to the given question.
The length of a copper is 1.6 centimeters.
As we all know that
1 meter = 100 centimeter
⇒ 1 centimeter = 1/100 meters or 10^-2 meters
So, to find the length of the copper wire in meters. We have to convert 1.6 centimeters to meters.
Therefore,
The length of the copper wire in meters
= 1.6/100 meters
= 1.6 × 10^-2
= 1.6 times 10^-2 meters
Hence, the length of the copper in meters is 1.6 times 10^-2 meters.
