Nilam observed an Aeroplane flying in sky. She wanted to know is basic principle, so she
discussed with her elder brother Kamlesh, he explained that, the wings of an aeroplane are
designed in such a way that air above them moves faster than the air below them. When the
aeroplane runs on the runway in order to take off, the pressure of air above and below changes. It
is this difference in pressure which helps the aeroplane to take off. Nilam thanked him for such
explanation
a) What are the values shown in Kamlesh in giving such explanation?
(1)
b) How does the aero plane take off?
c) How does fast moving air above the wings affect air pressure?
d) Give an example other than this which shows high speed air accompanied by reduced
pressure​

Answer 1

Answer:

(a)science and rescpect values

(b)because the air above and below changes

(c)it helps in taking of
