AHertz
BNewton
CJoule
DPascal
Answer & Solution
Correct answer: A. Hertz
1. Frequency counts complete oscillations in each second.
2. The SI unit for frequency is the cycle per second, which is defined to be a hertz.
3. A cycle is one complete oscillation.
4. Newtons, joules and pascals measure force, energy and pressure instead.
