Answer:

Explanation:
F = Force
C = Drag coefficient equal for both aircrafts
ρ = Density of air
A = Surface area equal for both aircrafts
v = Velocity



Dividing the above two equations we get

The ratio of the drag forces is 
It is gonna be C 0.37 and 19.1

Explanation:
Answer:
400kj
Explanation:
h =mass × specific heat capacity × change in temperature
= 2×2000×[120-20]
=2×2000×100
=400000j
=400kj
