At an air show a jet flies directly toward the stands at a speed of 1200 km/h, emitting a frequency of 3500 hz, on a day when the speed of sound is 342 m/s. what frequency is received by the observers? (b) what frequency do they receive as the plane flies directly away from them?

This is what i found “in a gas turbine engine, the combustor or combustion chamber is fed high pressure air by the compression system. early gas turbine engines used a single chamber known as a can type combustor. today three main configurations exist: can, annular and cannular (also referred to as can-annular tubo-annular).” i hope this you for what your looking for. can you plz mark me brainliest?

The speed was not exceeded so it was slow
