Question

It was a dark and stormy night.Buffy hameard thunder exactly 6 secounds after she saw lightning , the temperature of air is 15°C . the speed light is 3×10^8 m/s

caculate the speed of sound ​

Answer 1

υ = 345.82 m/s

Step-by-step explanation:

The formula used to find the speed of sound in air, at different temperatures is given as follows:

`v = v_(0)\sqrt{(T)/(273) }`

where,

υ = speed of sound at given temperature = ?

υ₀ = speed of sound at 0°C = 331 m/s

T = temperature in K = 15°C + 273 = 298 k

Therefore, using these values in the equation, we get:

`v = (331 m/s)\sqrt{(298 k)/(273 k)}\\`

υ = 345.82 m/s
