​Which of the following is equivalent to 5 µm/ns?55​5 x 10-6m/s​5 x 106 m/s​5 x 103 m/s​5 x 10-3m/s

The equivalent of 5 µm/ns is 5 x 10^6 m/s.

Here's the step-by-step conversion:

1. First, understand that µm/ns is a unit of speed, just like m/s. µm stands for micrometers, which is a unit of length, and ns stands for nanoseconds, which is a unit of time.

2. To convert µm/ns to m/s, we need to convert micrometers to meters and nanoseconds to seconds.

3. There are 1,000,000 (10^6) micrometers in a meter and 1,000,000,000 (10^9) nanoseconds in a second.

4. Therefore, 5 µm/ns is equivalent to 5 * (10^6 m/10^9 s) = 5 * 10^-3 m/s.

5. However, because we are dividing by a fraction (10^6/10^9), we can simplify this to 5 * 10^6 m/s.

So, the correct answer is 5 x 10^6 m/s.
