On a winter day sound travels 336 meters in one second. Find the atmosphere temperature. Speed of sound at `0^@C=332ms^-1`.

Options

A. `7^@C`
B. `10^@C`
C. `17^@C`
D. `15^@C`

Answer

A

Explanation

The speed of sound is proportioN/Al to the square root of the absolute temperature.
The speed of sound at `0^@C or 273 K is 332ms^-1`. If the atmosphere is T
`(336ms^-1)/(332ms^-1)=sqrt(T/(273K))`
or `T=(336/332)^2xx273K=280K`
`or T=7^@C`
