Which part of the wing of a swept - wing aircraft stalls first?
- Both stall together.
- Root stalls first.
- Tip stalls first.
why tip? In swept-wing aircraft, the airflow partially moves toward the wingtip (the "spanwise flow" effect), causing a different lift distribution compared to straight wings. To avoid stability and controllability issues during a stall, the aerodynamic design is often optimized so that the wing root stalls before the tip.

If pressure on a liquid increases, whilst temperature is held constant, the volume will
- slowly decrease.
- remain constant.
- slowly increase.
doesn't the quation is PV divided by T， so the pressure and volume will be inversely proportional with each other?
