Question

When a weight is tied at the end of the street, and his pullback and released, he creates a pendulum.The time it takes for the pendulum to swing out and return to its original position is called the period, depends on the length of the stringFor small release angles, like the one here we can use the equation……

Answer 1

Given the formula:

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

If T = 1.32 s, and g = 9.8 m/s²; to find L:

`\begin{gathered} 1.32=2\pi\sqrt{(L)/(9.8)} \\ \\ (1.32)/(2\pi)=\sqrt{(L)/(9.8)} \\ \\ ((1.32)/(2\pi))^2=(L)/(9.8) \\ \\ 9.8*((1.32)/(2\pi))^2=L \end{gathered}`

L = 0.4325 meters
