A simple pendulum oscillates between $4\mathrm{.}0^($as measured from the vertical$)$ on the surface of Earth. The length of the pendulum is $0\mathrm{.}60$ m$.$ Define t$\_$full as the amount of time that the pendulum takes to move from $8\mathrm{.}0^$ to $-8\mathrm{.}0^,$ and define t$\_$half as the amount of time that the pendulum takes to move from $4\mathrm{.}0^$ to $-4\mathrm{.}0^$ during the same swing. Compare the two times by determining the ratio t$\_$full $/$t$\_$half. t$\_$full $/$t$\_$half $=$
