Question 1: Two springs, one with spring constant of 12 N/m and the other with 24 N/m are suspended from a vertical rod. An identical mass is hung on each spring. What is the extension of the second spring when the extension on the first is 0.12 m? show your calculations below.
Question 2: What is the period of a spring with spring constant of 12 N/m when a mass of 0.20 kg is suspended from it? show your calculations below.
Question 3: The period of a pendulum is 1 second. What is the length of the pendulum? show your calculations below.
