What is the frequency of the given oscillation, in Hz? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
Use the following prompt for questions 1-2. Alexandra and Sal are conducting an experiment to study pendulums. In their first experiment, Alexandra and Sal changed the length of the pendulum and measured its period. In their second experiment, the mass of the pendulum bob was varied, and period was measured. 1. Before running the experiments, Sal hypothesized that increasing the mass of the pendulum would result in an increase in the pendulum's period. Was Sal correct? A. Sal was correct because mass is the only variable that will affect the period of the pendulum. B. Sal was correct because mass and length both affect the period of the pendulum. C. Sal was incorrect because only the length of the pendulum will affect the period of the pendulum. D. Sal was incorrect because only the initial angle will affect the period of the pendulum. inate Education TM, Inc.

Required information The period T of a simple pendulum is given by T = 2√ L/g where L is the length of the pendulum and g is the acceleration due to gravity. Assume g = 9.80 m/s² exactly and that L = 0.742 ± 0.003 m. Estimate T, and find the uncertainty in the estimate. Use pi = 3.1416. The estimated period is s. (Round the final answer to five decimal places.) The uncertainty in the period estimate is s. (Round the final answer to six decimal places.)
Pls help ASAP. Pls show all work and calculations and include units for final answers.
