The "lead" in pencils is a graphite composition with a young's modulus of approximately 1.0 ✕ 109 n/m2. calculate the change in length (in mm) of the lead in an automatic pencil if you tap it straight into the pencil with a force of 4.8 n. the lead is 0.70 mm in diameter and 59 mm long. (enter the magnitude.)
