(a) Calculate the tension (in N) in a vertical strand of spiderweb if a spider of mass 7.00 x 10 kg hangs motionless on it. (Enter a number.) 0.0006867 Z (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 The strand sags at an angle of 13.0 below the horizontal. (Enter a number.) X N Compare this with the tension in the vertical strand (find their ratio). (Enter a number.) (tension in horizontal strand) / (tension in vertical strand) = 2.22
