Name the physical quantities which are measured in the following unit
ns

Explanation

To solve the question regarding the physical quantities measured in the unit "ns" (nanoseconds), we can follow these steps:

### Step 1: Understand the Unit
- Nanosecond (ns) is a unit of time. It is defined as one billionth of a second, or \( 1 \, \text{ns} = 10^{-9} \, \text{s} \).

### Step 2: Identify the Physical Quantity
- The primary physical quantity that is measured in nanoseconds is time.
