Question

at what temperature velocity of sound in air is 1.5 times the velocity at 7 degree Celsius

Answer 1

For small temp. , Speed of sound = 332+0.61t where t is the temp.
At 7°C , v = 332+0.61*7 = 336.27m/s
Now , 336.27*1.5 = 504.405m/s
504.405 = 332 + 0.61t
t ≈ 282.7°C

Answer 2

Answer:

correct answer is 357°c
