Question

The temperature in a room is 56°C what would be the velocity of a soundwave be at this temperature ?

A. 1856.2 Hz
B. 265.2 Hz
C. 495.2 Hz
D. 364.6 Hz

Answer 1

Answer: 364.6 Hz

thank me later

Answer 2

D.
`364.6ms^(-1)`

Step-by-step explanation:

The speed of sound in dry air is given approximately by

`velocity_(new)=velocity(sound)+0.6*T_(Celcius)\\=331.4+0.6*56\\=364.6ms^(-1)`
