Why are different safety factors used for the design of aircraft, nuclear reactors and elevators?
Safety factors account for unknown factors and anomalies as well as practicality and economics. For example the aircraft industry uses small safety factors, otherwise flight would not be possible, while elevators use very high safety factors because warnings on maximum weight allowances are often ignored.
Why is the ACT math so different than the math learned in school.
Because you are not just being tested on your math knowledge, but you are also being tested on ingenuity and skill to solve unusual problems.
Why is the Coriolis effect important?
Because it effects all kinds of trajectories differently, depending upon where you are on our planet.
