1. a student had no thermometer, so in order to measure the temperature, she resourcefully used the following procedure. she accurately measured a distance of 100 m from a wall, then struck two stones together so that each new strike coincided with the echo from the previous strike. the student found that the time to make 150 strikes was 92s. to the nearest degree, what was the air temperature? 2. a lightning flash is seen 10s before the rumble of the thunder is heard. find the distance to the lightning flash if the air temperature is 2o c degrees. ( speed of light: c=3*10^8m/s)
