Solution:
Solution:
For A
$$R = C_p - C_v = 7$$
$$C_{V} = \frac{fR}{2} = 22 \Rightarrow f= \frac{44}{7} = 6.3 $$
$$ f \simeq6 \begin{matrix} \to &5 \left(\text{Rotation}+\text{Translatioal}\right)\\ \to &1 \left(\text{Vibration}\right)\end{matrix} $$
For B
$$ R = C_{P} -C_{V} =9 $$
$$ C_{V} = \frac{fR}{2} = 21 \Rightarrow f= \frac{42}{9} $$
$$ f \simeq 5 \begin{matrix} \to &5 \left(\text{Rotation}+\text{Translatioal}\right)\\ \to &0 \left(\text{Vibration}\right)\end{matrix}$$
