A) 4
B) 2
C) \[{{F}_{1}}={{F}_{2}}=F(say)\]
D) \[({{k}_{1}}+{{k}_{2}})F=-{{k}_{1}}{{k}_{2}}y\]
Correct Answer: C
Solution :
Key Idea: Since both gases are monoatomic ratio of specific heats is same for both. The velocity of sound is given by \[=\frac{Force}{Length}=\frac{[ML{{T}^{-2}}]}{[L]}=[M{{T}^{-2}}]\] where P is pressure, p is density and y is ratio of specific heats. \[[ML{{T}^{-2}}]\] \[=[M{{L}^{-1}}{{T}^{-2}}]\] (since \[[M{{L}^{2}}{{T}^{-1}}]\] and \[\alpha =\frac{\Delta {{i}_{C}}}{\Delta {{i}_{g}}}\] are same for both) Given, \[\Delta {{i}_{C}}\] \[\Delta {{i}_{g}}\] \[\alpha =0.96,\Delta {{i}_{E}}=7.2,\]You need to login to perform this action.
