Answer:
quartz clocks have gears inside them to push the hands around the clock face, measuring seconds, minutes, and hours with precision.To the contrary, when electricity passes through quartz, it vibrates at a precise frequency — an exact number of times per second.
if we see carefully that formula of acceleration you find that it is basically derived from fundamental quantities therefore acceleration is called a derived quantities.
