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.
