D

Magnetic flux

Step-by-Step Solution

  1. Identify the Physical Quantity: The question asks for the quantity measured by the unit 'Hertz'.
  2. Source Definition: According to the SI system, the hertz (symbol: Hz) is the SI derived unit for frequency .
  3. Physical Meaning: It is defined as the number of cycles or waves that pass a given point in one second (1 Hz=1 s−11 \text{ Hz} = 1 \text{ s}^{-1}) . It is named after the physicist Heinrich Hertz .
  4. Evaluate Other Options:
  • Force: The SI unit is the Newton (N) .
  • Electric charge: The SI unit is the Coulomb (C) .
  • Magnetic flux: The SI unit is the Weber (Wb) .
  1. Conclusion: Hertz is the unit of Frequency.
