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)

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
