A) 516 m/s
B) 450 m/s
C) 310 m/s
D) 746 m/s
Correct Answer: B
Solution :
As\[v\propto \sqrt{T}\Rightarrow \frac{{{v}_{2}}}{{{v}_{1}}}=\sqrt{\frac{{{T}_{2}}}{{{T}_{1}}}}\] \[\Rightarrow \] \[\frac{{{v}_{s}}}{400}=\sqrt{\frac{(273+227)}{(273+27)}}=\sqrt{\frac{5}{3}}\] \[\Rightarrow \] \[{{v}_{s}}=400\sqrt{5/3}=516\,m/s\]You need to login to perform this action.
