Pure aluminum is malleable, which means that it can be pounded or stretched into different shapes. You are given a small aluminum cube, with side length 5.0 mm. The goal is to shape this cube so that 2.0 A current flows through it when connecting the two ends to the terminals of 12 V battery. a) To what cross-sectional area A and length L should you stretch the cube, and how should the battery be…
