1.	When a mass is suspended on a metallic wire, the length of the wire increases slightly.if the Young's moduli of iron and glass are 190xx10^-19Nm^-2 and 65xx10^9Nm^-2 respectively which is more elastic?justify your answer.
Answer» Answer :Iron is more ELASTIC because its YOUNG's modulus is greater than that of GLASS.
