The speed of sound in air at 0°C is 332 m/s. If it increases at the rate of 0.6 m/s per degree,what will be the temperature when the velocityhas increased to 344 m/s? |

Answer» The SPEED of SOUND in air at 0℃ = 332m/sNow, If it increases at the rate of 0.6m/s per DEGREE,Then, Speed at x℃ = (332 + 0.6x)℃Thus, 344 = 332 + 0.6x ⇒ 344 - 332 = 0.6x ⇒ 12 = 0.6x ∴ x = \frac{12}{0.6} = 20℃ |
