Now an identical spider (mass m) on an identical silk of the same length, L, is blown by the wind and ends up swinging like a simple pendulum with the same period of oscillation, T. Using the parameters provided, what is the spider's mass in grams? Round your answer to three significant figures. (The silk is 4 1 in diameter, Y = 0.7 100 N/m is the Young's modulus of spider silk, g = 9.8 m/s, and the area of a circle is A m = r. 1 m = 106 m, 1 g = 10 kg)
