There both things you use in the morning time
Dual credit is better, AP classes are so stressful and many don’t pass the exam, making it a waste of time since you won’t get college credits. The collegeboard is honestly a scam, you pay to take an exam that you’re not guaranteed to pass. Especially with the pandemic happening, AP students are forced to learn all the topics in less time due to online school. In my experience, AP classes are not worth it. Even if you pass the exam, many colleges don’t accept the credits so it’s pointless.
A supersonic aircraft is an aircraft able to fly faster than the speed of sound (Mach number1). Supersonic aircraft were developed in the second half of the twentieth century and have been used almost entirely for research and military purposes. Only two, Concorde and the Tupolev Tu-144, ever entered service for civil use as airliners. Fighter jets are the most common example of supersonic aircraft.
The aerodynamics of supersonic flight is called compressible flow because of the compression (physics) associated with the shock waves or "sonic boom" created by any object travelling faster than sound.
Aircraft flying at speeds above Mach 5 are often referred to as hypersonic aircraft.
