JD2016 has left comment on chesters1234's question:
Actually Chesters1234 you can produce oxygen by pressurising air. It's part of the Liquefaction process used to produce liquid oxygen. Air is compressed (pressurised) to 60Bar and cooled before being allowed to expand which causes it to turn to liquid air before being fractioanted into liquid oxygen and liquid nitrogen.

JD2016 has left comment on Edigno92's question:
It's a bad question. A radial is the magnetic bearing outbound from a VOR. So the 3rd answer is correct in so far as it is FROM but a "beacon" could be an NDB (non directional beacon) and it is VORs (the 2nd answer) that are relevant.
The 150 VOR radial is QDR 150 - 150 degrees from that VOR - which is QDM 330 - i.e. you would have to fly a heading (assuming no wind) of 330 to fly to that VOR. Read comment

question should specify.....diodes connected in parallel and forward biased....i think Read comment

JD2016 has left comment on diaandrita's question:
Another way of asking this question would be:
"What is the effect of flaps on critical angle of attack?" Read comment

JD2016 has left comment on Ptarbin's question:
What you are missing is the 2 and the square or square root!
S=distance =10
a= acceleration =g = 9.81 m/s2 - rounded up to 10.
u = initial velocity = 0 (assuming it is dropped from rest at 10m).
Fill in the equation:
10 = 0 + 0.5 x 10t**2
2= t**2
t= square root of 2 seconds = 1.414 seconds. Read comment
