A 5.0 x 102-N object is hung from the end of a wire of cross-sectional area 0.010 cm2. The wire stretches from its original length of 200.00 cm to 200.50 cm. Determine the Young's modulus of the wire. O 2.0 x 1011 N/m2 O 5.0 x 1012 N/m2 O 2.0 x 109 N/m2 O 1.0 x 1011 N/m2 O 1.0 x 109 N/m2In a certain clock, a pendulum of length L1 has a period T1 = 0.95 s. The length of the pendulum is adjusted to a new value L2 such that T2 = 1.0 s. What is the ratio L2/L1? O 0.95 O 1.1 O 1.0 O 1.3 O 0.90A simple pendulum consists of a ball of mass m suspended from the ceiling using a string of length L. The ball is displaced from its equilibrium position by a small angle 9. What is the magnitude of the restoring force that moves the ball toward its equilibrium position and produces simple harmonic motion? 0 mgl.(sin9) O mglsine) O mglcosQ) 0 mg ka What is the period of a pendulum consisting of a 6-kg object oscillating on a 4-m string? O 2.0 s O 0.50 s O 1.0 s O 0.25 s O 4.0 s
