(a) Calculate the tension (in N) in a vertical strand of spiderweb if a spider of mass 9.00 x 10 kg hangs motionless on it. (Enter a number.) 0.000882 N (b) Calculate the tension (in N) in a horizontal strand of spiderweb if the same spider sits motionless in the middle of it much like the tightrope walker in the figure. 5.00 -5.0 TR TR :. The.strand. gags.at an angle of 12.09 below the horizontal. (Enter a number.) X N Enter a number. Compare this with the tension in the vertical strand (find their ratio). (Enter a number.) (tension in horizontal strand)/(tension in vertical strand) = X
