Which part of the wing of a swept - wing aircraft stalls first?
•  Both stall together.
•  Root stalls first.
•  Tip stalls first.

lucdam56 asking:
•  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
•  decrease.
•  remain constant.
•  increase.

Ricky HO asking:
•  doesn't the quation is PV divided by T， so the pressure and volume will be inversely proportional with each other?
