14. The accompanying data on x  current density

(mA/cm2) and y  rate of deposition (mm/min) appeared in the article Plating of 60/40 Tin/Lead Solder for Head Termination Metallurgy (Plating and Surface Finishing, Jan. 1997: 38—40). Do you agree with the claim by the article s author that a linear relationship was obtained from the tin—lead rate of deposition as a function of current density ? Explain your reasoning.
