I was given the equation for the period of oscillation thought a tunnel:[tex]T=2 \pi \sqrt{\frac{R_E^3}{GM_E}}[/tex](adsbygoogle = window.adsbygoogle || []).push({});

then asked how I could transform that into [tex]T=2 \pi \sqrt{\frac{R_E}{g}}[/tex]

which I did through the idea that [tex]g=\frac{GM_E}{R_E^2}[/tex]

The the question asked what would be the period if tunnels were made though the moon?

and what practical problem regarding these tunnels on Earth would be removed if they were built on the Moon?

I'm clueless here
