Answer:
1.) Oil and gas environment
2.) Mechanical engineering and electrical environment.
Explanation:
1.) Oil and gas environment.
Electricity and electric discharge are recognized as serious workplace hazard in oil and gas companies, exposing employees to burns, fires, and explosions.
2.) Mechanical engineering and electrical environment.
Electricity or electric discharge has long been recognized as a serious workplace hazard, exposing employees to electric shock, electrocution, burns, fires, and explosions. Workers could die from electrocutions at work. This is

Answer:
the frequency heard by the observer is equal to 2677 Hz
Explanation:
given,
velocity of the observer = 17 m/s
speed of the sound = 343 m/s
velocity of the source = 0 m/s
frequency emitted from the source = 2550 Hz

velocity of observer is negative as it is approaching the source. f = 2676.38 Hz ≈ 2677 Hz
hence, the frequency heard by the observer is equal to 2677 Hz
