What is the power of 'second' in the SI unit of acceleration ?

-2

The correct answer is option 3. -2.

The power of 'second' in the SI unit of acceleration is -2.

Acceleration (\(a\)) is measured in meters per second squared (m/s²) in the International System of Units (SI). In this unit, the 'second' is raised to the power of -2, indicating that it appears in the denominator and is squared. Therefore, the power of 'second' is -2.
