Suppose that you time this pendulum, and it completes exactly 68.0 complete cycles in 100 s. [Hint: think carefully about all given distances.] 5. (5 pts) Which choice best represents the value of g in the vicinity of this pendulum?

Respuesta :

Answer:

Explanation:

Number of oscillations in 100 s is 68.

time taken to complete one oscillation = 100 / 68 s = 1.47 s

Use the formula for the time period of an oscillating body

[tex]T = 2\pi \sqrt{\frac{L}{g}}[/tex]

[tex]T^{2} = 4\pi^{2} \frac{L}{g}}[/tex]

In this equation substitute the value of T amd L and then find the value of g.
