Answer 1

HEY MATE UR ANS IS⤵



The ratio of velocity of sound in hydrogen to that in helium at same temperature is IDENTICAL



*HOPE IT HELPS U*❤❤✌

Answer 2

Velocity of sound in a gas is inversely proportional to sqrt of molecular mass.

So the velocity through hydrogen to helium=√{M(he)/M(h}

                                                                         =√(4/2)=√2.ans..
