O WORDS POWERED BY TINY QUESTION 9 10 points Save Answer As a rod is heated, it expands outward toward both ends (from the middle). If a rod were cut in half at its center so that it has four ends and if the two new, shorter rods were placed end to end, by how much would the overall expansion of the rod change? Ignore the small amount of metal lost in the cutting process. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac). BIUS Paragraph Arial 10pt v E v EVAV AT & BBQ ... O WORDS POWERED BY TINY
