What is the frequency heard by the observer

Reference no: EM135201

Q1. A train at rest emits a sound at a frequency of 1045 Hz. An observer in a car travels away from the sound source at a speed of 37 m/s. What is the frequency heard by the observer? Assume the speed of sound in air tube 340 m/s.

Q2. Compute the percent error made over one mile of distance by the "5 second rule" for estimating the distance from a lightning strike for each of following temperatures. The "5 second rule" says that for every 5 seconds between seeing a lightning strike and hearing the associated sound, the lightning is 1 mile distant. Assume 1 mile equals 1610 meters.
