Q. The speed of sound in hydrogen at NTP is 1270m/s . Then the speed in a mixture of hydrogen and oxygen in the ratio 4:1 by volume, (m/s) will be 1)635 2)318 3)158 4)1270

Q. The speed of sound in hydrogen at ntp is 1270 metre per second the speed in the mixture of hydrogen and oxygen in ratio for ratio 1 by volume in metre per second will be
