- #16-adue to its position at a height, (b) due to its elongated stretched state.Ans : P.E. due to its position at a height: Water at a height has P.E. stored in it. Falling water from a height can be used to do work like turning a wheel, (b) P.E. due to its elongated stretched state: A stretched rubber band (elongated state) has potential energy. It does work in restoring itself to its original state. A pebble placed on the stretched rubber catapult is thrown away when it is released to restore its original state.
