A cylindrical wire of radius R elongates when subjected to a tensile force F. Let Lorepresent the initial length of the wire and let L1 represent the final length. Young's modulusfor the material is given byFL,*R°(L, - L,)Assume that F = 800 = 1 N, R = 0.75 ± 0.1 mm, Lo = 25.0 ± 0.1 mm, and L1 = 30.0 ± 0.1mm.Estimate Y, and find the uncertainty in the estimate.a.b.Of the uncertaintțes in F, R, Lo, and L1. only one has a non-negligible effect on theuncertainty in Y. Which one is it?

2. The velocity v of a falling parachutist is given by v = 9m (1 – e-c/m)t) where g = 9.81 m/s?. For a parachutist with a drag coefficient c = 15 kg/s, compute the mass m so that the velocity is v = 36 m/s at t = 10 s. Use (a) bisection method, (b) false position method. Use the program you created in exercise 4 or use google sheet. If you use google sheet include computation of epsilon_a. The table of values ends when epsilon_a is less than or equal to 0.0000000001.
