A) \[\frac{2{{T}_{\alpha }}{{T}_{\beta }}}{{{T}_{\alpha }}+{{T}_{\beta }}}\]
B) \[{{T}_{\alpha }}+{{T}_{\beta }}\]
C) \[\frac{{{T}_{\alpha }}{{T}_{\beta }}}{{{T}_{\alpha }}+{{T}_{\beta }}}\]
D) \[\frac{1}{2}\left( {{T}_{\alpha }}+{{T}_{\beta }} \right)\]
Correct Answer: C
Solution :
\[{{T}_{av}}=\frac{{{T}_{\alpha }}{{T}_{\beta }}}{{{T}_{\alpha }}+{{T}_{\beta }}}\]If \[\alpha \] and B are emitted simultaneously.You need to login to perform this action.
