Question

The speed of sound in air at 0 degree C is 332m/s.If it increases at the rate of 0.6 m/s per degree, what will be the temperature when the velocity has increased to 334 m/s ?​

Answer 1

Answer:

Explanation:

Intial velocity(u)⇒ 332m/s

Final velocity(v)⇒334 m/s

Speed of sound in air at 0⁰C ⇒ 332m/s

Speed increases at a rate of 0.6m/s per degree

Temperature at 344 m/s ⇒ T⁰c

Difference in velocities ⇒v-u

                                       ⇒344 m/s - 332 m/s

                                        ⇒12 m/s

NOW WE KNOW THAT

Increase in temperature corresponding to the increase in velocity⇒

Difference in velocities / increases at the rate of m/s per degree

∴ 12/0.6

⇒120/6

⇒20⁰C

∴temperature at velocity 344m/s ⇒speed of sound in air at degree C + Increase in temperature corresponding to the increase in velocity

⇒ 0⁰C + 20⁰C

⇒ 20⁰C
