Aplane is moving at 50.0 m/s at 30 degree west of south relative to ground. the wind velocity is 10 miles at 60 degrees west of north calculate the plane velocity relative to the air. (you need to draw the picture in x-y coordinate and then calculate)

that the claims meet official rules.

don't misinterpret the claims

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
