Hey. I would like to thank everyone in advance for reading my questions and for helping me. I am really greatful for it. I have probably put 3 or 4 hours into these questions but just can not seem to be able to break them down and figure out how to come up with a solution. Question 1: A pendulum which is 2.00m long makes 84.5 compleate oscillations in 4.00 min. What is the acceleration of gravity at this spot? Show all work and formulas. Question 2: A grandfather clock uses a large mass suspended at the end of a metal rod as a timing mechanism. The back and forth movement of the mass provides the ticks and tocks for this clock. An interesting characteristic of this type of clock is that it is sensitive to temperature. Imagine that three identical grandfather clocks are set to the same time and then allowed to run for one week. The clock on the left ran in a room that was hot. The clock on the right wan in a room that was cold. The clock in the center ran in a room that was room temprature. Sketch the approximate times that the clocks in the hot and cold rooms would show. Explain your answer. (clock at room temprature points to exactly 9 o'clock). Thank-you so much for your time and help. any help givin would give me a great boost here :).
