Aspecimen of copper having a rectangular cross section 15.2 mm x19.1 mm (0.6 in. x 0.75 in.) is pulled in tension with 44500 n(10000 lbf) force, producing only elastic deformation. calculate the resulting strain.

Two solutions of the same uv-absorbing molecule were analyzed by uv-vis spectroscopy on the same instrument using 1 cm pathlength cells. use data from the table to calculate by what percentage the concentration of solution b is compared to that of solution a.sample absorbance at 315nm a 0.45 b 0.80
