A) 1 : 2
B) 4 : 1
C) 2 : 1
D) 1 : 4
Correct Answer: C
Solution :
Relation for the velocity of sound is \[\upsilon =\sqrt{\gamma \frac{p}{\rho }}\] hence\[\frac{{{\upsilon }_{1}}}{{{\upsilon }_{2}}}=\sqrt{\frac{{{P}_{1}}}{{{\rho }_{1}}}\times \frac{{{\rho }_{2}}}{{{P}_{2}}}}=\sqrt{\frac{4}{1}}=2:1\]You need to login to perform this action.
