a) Calculate the speed of sound in air at a temperature of 12.0degrees C given that the speed of sound in air at a temperature of 0.0 degrees C is 331 m/s.
b) A lightning flash is seen in the sky and 8.2 s later the boomof the thunder is heard. The temperature of the air is 12.0 degreesC. How far away is the lightning strike? [Hint: Light is anelectromagnetic wave that travels at a speed of 3.00 x 10^8 m/s inair.]
