The frequency of a tuning fork is 256 Hz. What is the number of oscillations it makes in 1 minute?
Correct: A
Since the time is given in minutes, we first convert it to seconds: 1 minute = 60 seconds. The number of oscillations the tuning fork makes in 1 minute is given by the equation n = f * t, where n is the number of oscillations, f is the frequency, and t is the time in seconds. Substituting the given values, we get n = (256 Hz) * (60 s) = 15360.
