The pull of the moon on earth's tidal bulge is causing the earth to gradually rotate faster the earth to slowly expand in size the earth to rotate slightly slower the moon to move closer to earth

Not 100% but i think it'll cause the earth to rotate slightly slower, its definitely not the last one though

Answer;

the earth to rotate slightly slower

The pull of the moon on Earth's tidal bulge is causing the earth to rotate slightly slower.

Explanation;Tidal bulge results from the gravitational attraction between the moon and the earth which causes the ocean waters to be pulled towards the moon, such that as the earth rotates the location of the affected water change.Tidal bulges are created on opposite sides of the Earth due to the moon's gravitational force and inertia counterbalance.The tidal bulge produced on Earth by the moon is causing the moon to slowly move further from Earth. The average tidal bulge is synchronized with the orbit of the moon and the earth rotates under the tidal bulge over a day.

Since the pully is a simple machine so the mechanical advantage is a 1
