A micro-actuator inside an automated pipette mechanism uses a high-precision alloy spring to control fluid delivery.
During a calibration sequence, the work done to compress this spring is 0.36 J.
The spring constant of the alloy spring is 450 N/m.
Calculate the compression of the spring, giving your answer in metres.
