Hi there!
We can use the following equation for the period of a pendulum:
[tex]\large\boxed{T = 2\pi \sqrt{\frac{L}{g}}}[/tex]
T = Period (s)
L = length of simple pendulum (.75 m)
g = acceleration due to gravity (9.8 m/s²)
Plug in the values:
[tex]T = 2\pi \sqrt{\frac{.75}{9.8}} = \boxed{1.738 s}[/tex]
