During a calibration test of a micro-electro-mechanical system (MEMS) sensor, its acceleration aaa (in m s−2\text{m s}^{-2}m s−2) is related to its displacement xxx (in m\text{m}m) from the equilibrium position by the equation:
a+540x=0 a + 540 x = 0 a+540x=0What is the frequency of oscillation of the sensor?
23 Hz23\text{ Hz}23 Hz
86 Hz86\text{ Hz}86 Hz
3.7 Hz3.7\text{ Hz}3.7 Hz
150 Hz150\text{ Hz}150 Hz
