An airplane was moving 50 m/s to the north relative to the air at landing. The wind was blowing 5 m/s toward the south relative to the ground . What was the speed of the airplane relative to the ground at time of landing .

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

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

2.6 and i can kick good lol
