Question

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?

Answer 1

Step-by-step 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

`T = 2\pi \sqrt{(L)/(g)}`

`T^(2) = 4\pi^(2) (L)/(g)}`

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