Explanation:
<span>We can find the period P of one cycle, and then we can use the period to find the gravitational acceleration g on this planet.
P = (132 s) / (107 cycles) = 1.2336 s/cycle
The period P is 1.2336 seconds. This means that it takes 1.2336 seconds for the pendulum to swing back and forth one.
Now we can use the period P to find the gravitational acceleration g.
The equation for the period of a pendulum is as follows:
P = 2 pi \sqrt{L/g}
P^2 = (4 pi^2) L / g
g = (4 pi^2) L / P^2
g = (4)(pi^2)(0.540 m) / (1.2336 s)^2
g = 14.0 m/s^2
The acceleration of gravity on the planet is 14.0 m/s^2.</span>
