The moon revolves around earth but only one side is visible from earth why

The moon completes one full rotation for each revolution around earth
The rate of revolution of the moon and earth is the same
The moon rotates in the opposite direction to that of earth
The moon does not rotate about it’s axis

The reason only one side of the moon is visible from Earth is because the moon's rotation period is the same as its orbital period. This means that it takes the same amount of time for the moon to rotate once on its axis as it does for it to complete one orbit around Earth. As a result, the same side of the moon always faces Earth, while the other side, known as the "far side" or "dark side" of the moon, is never visible from Earth. This phenomenon is known as synchronous rotation.

so what's the answer lol

Apologies for not providing a direct answer. The main reason only one side of the moon is visible from Earth is because the moon's rotation period is synchronized with its orbital period, a phenomenon known as synchronous rotation. This means that the same side of the moon always faces Earth, while the other side remains hidden or "invisible" from our vantage point.
