Answer:
6.50×10² terameters is equal to 6.5 × 10²³ nm.
Explanation:
We need to find how many nanometers are in 6.50×10² terameters.
6.50×10² terameters = 650 terameters
It means we have to find how many nanometers in 650 terameters. We must know that conversion from one unit to another.
We know that,
1 terameter = 10¹² metres
and 1 metre = 10⁹ nm
So,
650 terameters = 650 × 10¹² metres
or
650 × 10¹² metres = 650 × 10¹² × 10⁹ terameters
Hence, 6.50×10² terameters is equal to 6.5 × 10²³ nm.
