Answer:
A simple pendulum takes 13 seconds to complete 26 oscillations. Its frequency is 2Hz and the time period is 0.5s
Explanation:
- For a simple pendulum, the number of oscillations completed per time is the frequency of oscillation. It can be obtained by the equation,
The time period of an oscillation can be expressed as,
- Let f be the frequency of oscillation, N be the number of oscillations completed in time t and T be the time period.
So as per definition,
...(1)
and
- In the question, it is given that,
N
t
- Then using equation(1),
f =
T =
