Question

What is the velocity of wave in monoatomic gas having pressure 1 kilopascal and density $2.6kg/m^{3}$

• A. $3.6m/s$
• B. $8.9 \times 10^{3}m/s$
• C. Zero
• D. None of these

Answer 1

Answer: (D)

None of these

Answer 2

$v = \sqrt{\frac{\gamma P}{\rho}} = \sqrt{\frac{\frac{5}{3} \times 10^{3}}{2.6}} = 25m/\sec$
