Question

Question Completion Status: One nano second times one kilometer/second is O a. 10-3m Ob. 10-6 m Oc 10+6m O d. 10-9m O e 10-12 km

Answer 1

Answer: $10^{-6}m$

Explanation:

We are asked to multiply  1 nano sec with 1 km/sec.

The conversion used from nano second to second

1 nsec = $10^{-9}sec$

The conversion used from km to meters:

1 km = 1000 m

$1nsec\times 1\frac{km}{sec}$

Putting the values we get:

$10^{-9}sec\times {\frac{1000m}{sec}=10^{-9}\times 10^3m=10^{-6}m$

Therefore, the given conversion is $10^{-6}m$
