A) 1600 m/s
B) 1532.19 m/s
C) 160 m/s
D) zero
Correct Answer: B
Solution :
\[R=\frac{8.3}{4.2}cal\,g/mol\,K\] \[{{C}_{V}}={{C}_{p}}-R\] \[=\left( 4.8-\frac{8.3}{4.2} \right)=2.824\] \[y=\frac{{{C}_{p}}}{{{C}_{V}}}=\frac{4.8}{2.824}=1.69\] Since, \[v=\sqrt{\left( \frac{3}{y} \right)}\times {{v}_{s}}\] \[=\sqrt{\frac{3}{1.69}}\times 1150\] = 1532.19 m/sYou need to login to perform this action.
