Test On Monday...please help!!! 1. The problem statement, all variables and given/known data My home is exactly 7.8 km from the Stadium where the 4th of July fireworks are held. The time difference between when I see a flash and when I hear the corresponding sound is 22.4073542085608 s. What is the temperature (in degrees Celsius) of the air? 2. Relevant equations Vsound = sqrt (GAMMA * R * T) / M 3. The attempt at a solution T = 20 degrees Celsius + 273 = 293 V = 7800/22.4073542085608 = 348.1 m/s T = Vsound^2 * M / GAMMA * R But I don't know M, GAMMA, or R???
