Answer:

pictures are below

Explanation:

V_{sound} \alpha \frac{1}{\rho} \Rightarrow \frac{v_{1}}{v_{2}} = \sqrt{\frac{\rho_{2}}{\rho_{1}}} = \sqrt \frac{4}{1} = 2 \Rightarrow v = \frac{v_{1}}{2} = \frac{v_{s}}{2}

velocity of sound in air -

Newtons formula = \sqrt{\frac{P}{\rho }}

Laplace formula (correct value )

= \sqrt{\frac{\gamma P}{\rho }}

-

Option 1)

\frac{v_{s}}{2}

This is correct.

Option 2)

\frac{v_{s}}{12}

This is incorrect.

Option 3)

12v_{s}

This is incorrect.

Option 4)

\frac{3}{2}v_{s}^{2}

This is incorrect.
