Show answer & explanation
Correct answer: C
Solution: Compute frequency using f = 1/T.
Convert period to seconds: T = 100 ms = 100 × 10^-3 s = 0.1 s.
Compute frequency in hertz: f = 1/T = 1/0.1 s = 10 Hz.
Convert to kilohertz: 10 Hz = 10 × 10^-3 kHz = 0.01 kHz = 10^-2 kHz.
Answer: The frequency is 10^-2 kHz (0.01 kHz).
