State the numberof significant figures in the `6.320 J `

Explanation

To determine the number of significant figures in the measurement \(6.320 \, \text{J}\), we can follow these steps:

### Step 1: Identify the digits in the number
The number given is \(6.320\). We will analyze each digit in this number.

### Step 2: Determine which digits are significant
- **Non-zero digits**: All non-zero digits (1-9) are always considered significant. In \(6.320\), the digits \(6\), \(3\), and \(2\) are non-zero and thus significant.
- **Zeros between significant digits**: Any zeros that are between significant digits are also considered significant. In this case, there are no zeros between significant digits.
