Question

the atmospheric temperature in Baguio City is 20°C. How fast does sound travel in the air​

Answer 1

Answer:

=343 m/s

Explanation:

solve it

Answer 2

Sound travels with the speed of 343m/s in Baguio City

• Speed of sound is directly proportional to the square root of the temperature of surroundings.
• According to newton`s formula, V=$\sqrt{\frac{\rho RT}{M} }$ (Here, ρ=$\frac{C_{P} }{C_{V}}$ for air)
• We know that the speed of sound increases by 0.6m/s per degree celsius rise in temperature.
• The velocity of sound at 0°C= 331m/s
• So the velocity of sound at 20°C=

331 + 0.6x20 = 331 + 12

= 343m/s
