Which of the following is `//` are correct .

Options

A.
B.
C.
D.

Answer

C

Explanation

Velocity of sound in air `(V)=sqrt((gammaRT)/(M))`
`rArrV^(2)alphaT (` in kelvin`)`
not `V^(2)alpha T (` in `.^(@)C)`
Hence `(B)` in incorrect
Velocity of transverse wave in a string `:`
`V=sqrt((T)/(mu))=V^(2)alphaT`
Hence `(C )` is a correct graph.
