Since Mercury has no atmosphere, there is no way of transmitting sound, so if you were on Mercury and playing a guitar or a ukulele or a piano, you would not hear anything, because there is no atmosphere to transmit that sound.
Pošto Merkur nema atmosferu, zvuk se ne može prenositi. Ako ste na Merkuru i svirate gitaru, ukulele ili klavir, ne bi ništa čuli, jer nema atmosfere koja bi prenosila taj zvuk. Bila bi potpuna tišina.
