It represents the energy consumed when 1 kilowatt of power is used for 1 hour.

Explanation

Young's Modulus is the ratio of stress to strain and measures stiffness of a material.

Since stress is measured in N/m² (or Nm⁻²) and strain is dimensionless, the unit remains Nm⁻².

Explanation

Deca (symbol: da) is the SI prefix that represents a factor of 10.

It is used to denote ten times the base unit, such as 1 decameter = 10 meters.

Explanation

The coulomb, also written as its abbreviation 'C', is the SI unit for electric charge.
