MCQ
Which of the following is $CORRECT$
  • A

  • B


  • D

Answer

Correct option: C.

c
Velocity of sound in air $\left( V \right) = \sqrt {\frac{{\gamma RT}}{M}} $

$ \Rightarrow {V^2}\alpha T$        (in kelvin)

not ${V^2}\alpha T$ (in ${\,^0}C$)

Hence $(B)$ is incorrect.

velocity of transverse wave in nastring 

$V = \sqrt {\frac{T}{\mu }}  = {V^2}\alpha T$
