1 Summary of Basic Probability. 2  In the following, the capital letters A, B, or C are used to represent some event like it will rain tomorrow or a computer chip is defective. The notation P(A) then stands for the probability of event A. 3  An experiment is any process yields a result or observation.
A pendulum is a string or stick with a weight or bob on the end. The pendulum follows the law of falling objects[ âan invisible force, gravity, pulls the pendulum toward Earth. The period of time it takes. a pendulum to complete one full swing is simply called the period. Three variables affect the period: the length of the pendulum, the. size of the arc it makes, and the mass of the bob. In this activity, youâll discover what happens if you change one or more of the. variables.
What is the period of a simple pendulum 80 cm long (a) on the Earth, and (b) when it is in a freely falling elevator? 10. The length of a simple pendulum is 0.760 m, the pendulum bob has a mass of 365 grams, and it is released at an angle of 12.0Â° to the vertical.. If a simple pendulum whose length is 1.50 m makes 72 oscillations in 3.00 min, what is the acceleration of gravity at its location? 5. A 2500 kg demolition ball swings on a cable 17.0 m long.
