In many keyboards, the key switches are built as air-filled parallel-plate capacitors with a spacing that decreases when the key is pressed. This change in spacing increases the capacitance, which connected circuitry registers as a keypress. Suppose the plate area on a key is 44.8 mm2 and the unpressed plate separation is 0.63 mm. If the circuitry registers a keypress when the capacitance changes by 0.476 pF, calculate the distance (in mm) the key must travel to register a keypress.
