wings
Lift is generated by every part of the airplane, but most of the lift on a normal airliner is generated by the wings. Lift is a mechanical aerodynamic force produced by the motion of the airplane through the air.
Frequency - number of waves (vibrations, revolutions, of cycles) that pass a given point per unit time.
the correct answer should be A
hope this helps :)
Acceleration =change in velocity/change in time.
So final speed minus initial velocity/time
3.1-v/2=a
For this problem to be solved, we make use of the de Broglie formula which is written below as follows:
λ = h/mv
where h is 6.626×10⁻³⁴ J·s
9.74 × 10⁻³⁵ m = 6.626×10⁻³⁴ J·s/ (m)(46.9 m/s)
Solving for m,
<em>m = 0.145kg</em>
