A scallop forces open its shell with an elastic material called abductin, whose Young's modulus is about $2\mathrm{.}0106$N$/$m$2$

$.$ If this piece of abductin is $4\mathrm{.}5$ mm

thick and has a cross$-$sectional area of $0\mathrm{.}40$ cm$2$

$,$ how much potential energy does it store when compressed $1\mathrm{.}3$ mm

$?$
