Consider a thunderstorm with a flash of lightning followed by acrash of thunder. The time delay between the lightning flash andthe sound of the thunder is 5.0 seconds. The intensitylevel of the sound for your location isabout 70 dB and the duration of the thunderclap isabout 4.0 s. The speed of sound in airis 344 m/s.

A) Estimate the distance sound travels, which provides anestimate of the distance to the lightning flash.

B) Calculate the sound intensity in W/m^2

C) Assume the sound was generated at the site of thelightning flash and assume the sound was transmitted uniformly inall directions. Use the estimated distance to estimate the averagesound power generated by the thunder.

D) Estimate the sound energy released by a lightningstrike.
