(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.) 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. w The strand sags at an angle of 12.0 below the horizontal. (Enter a number.) N Compare this with the tension in the vertical strand (find their ratio). (Enter a number.) X (tension in horizontal strand) / (tension in vertical strand)
