The value 4.02 × 10⁵ Pa represents a pressure measurement in Pascals (Pa), which is the SI unit for pressure. Specifically, this is in scientific notation, where:

• 4.02 is the coefficient.
• 10⁵ indicates that the decimal point should be moved five places to the right.

So, 4.02 × 10⁵ Pa is equivalent to:

402,000 Pa or 402 kPa (kilopascals).

This might represent a pressure, for example, in atmospheric conditions, a mechanical system, or in a scientific experiment.

Tip: When dealing with scientific notation, ensure the coefficient is between 1 and 10 to maintain standard form (e.g., 4.02 × 10⁵ instead of 0.402 × 10⁶).
