A) A has one vibrational mode and B has two
B) Both A and B have a vibrational mode each
C) A is rigid but B has a vibrational mode
D) A has a vibrational mode but B has none
Correct Answer: D
Solution :
For A \[R={{C}_{p}}-{{C}_{\text{v}}}=7\] \[{{C}_{\text{v}}}=\frac{fR}{2}=22\Rightarrow f=\frac{44}{7}=6.3\] For B \[R={{C}_{p}}-{{C}_{\text{v}}}=9\] \[{{C}_{\text{v}}}=\frac{fR}{2}=21\Rightarrow f=\frac{42}{9}\]You need to login to perform this action.
