If a linear analog accelerometer outputs 10 V and 0 V for +20g and -20g, respectively, it has a sensitivity of 0.25 V/g since a 1g change in acceleration causes a change of 1V in its output. If an analog accelerometer outputs 3.3 V and 0 V for +16g and -16g, respectively, what is its sensitivity? What voltage should it display when the acceleration is zero?
