4: (10 marks) An experiment was conducted to determine the relationship between tem nd wear rate at the hore surface of the barrel at or near the commencement of rifling. The d or wear rate of propellant (m/s) and the maximum bore temperature (Cº) were recorded Temperatures C 975 960 950 965 855 830 815 805 725 wear rate (m/s) 0.1 0.097 0.078 0.1 0.065 0.055 0.045 0,029 0.028 alculate: the sample correlation coefficient r of the wear rate, then decide whether the relationship eak moderate or strong
