The velocities of sound in an ideal gas at temperature T_(1) and T_(2) K are found to be V_(1) and V_(2) respectively. If ther.m.s velocities of the molecules of the same gas at the same temperatures T_(1) and T_(2) are v_(1) and v_(2) respectively then

Answer»

`v_2 = v_1 (V_1/V_2)`
`v_2 = v_1 (V_2/V_1)`
`v_2 =v_1 SQRT(V_2/V_1)`
`v_2 = v_1 sqrt(V_1/V_2)`
