At `10^5 Nm^(-2)` atmospheric pressure the density of air is `1.29 kg m^(-3)`.If `gamma=1.41` for air, calculate the speed of sound in air.

If the density of air at NTP is 1.293kg//m^(3) and gamma=1.41 , then the velocity of sound in air at NTP is :

The density of air is 1.293 kg m^3 . Express it in cgs units.

Given the density of air is 1.29 kg m^(-3) . Then, the relative density of air is ________.

The corrected Newton's formula for velocity of sound in air is v=sqrt((gamma P)/(rho)) , where P is pressure and rho is density of air, gamma =1.42 for air. At normal temperature ane pressure, velocity of sound in air =332m//s . Read the above passage and answer the following question: (i) How do the sound horns protect us from the oncoming vehicles ? ltbr. (ii) How does a sand scorpion fing its prey? (iii) Will the velocity of sound in air change on changing the pressure alone?

Calculate the velocity of sound in air at NTP. The density of air at NTP is (1.29g)/(L) . Assume air to be diatomic with gamma=1.4 . Also calculate the velocity of sound in air at 27^@C .

What is the effect of pressure on speed of sound in air?

A blast given a sound of intensity 0.8 W//m^(2) at frequency 1kHz. If the denstiy of air is 1.3 kg//m^(3) and speed of sound in air is 330 m/s, then the amplitude of the sound wave is approximately

By using (i) Newton's formula and (ii) Laplace's formula, calculate the speed of sound in air at standard pressure and temperature. The density of air is 1.293 kg//m^(3) . gamma = 1.4 for air.
