Explanation:
- Aerodynamic drag: The resistance force experienced by an object moving through a fluid (air) is called aerodynamic drag. It is denoted by D and is given by D = bv^2, where b is a constant.
- Power output: The power output of an aeroplane is the rate at which work is done. It is given by the product of force and velocity. In this case, the force is the aerodynamic drag and the velocity is constant. Therefore, the power output is P = Dv = bv^3.
- Proportional: If one quantity is proportional to another, it means that they increase or decrease together in a linear manner. In this case, the power output is proportional to v^3, which means that if the speed of the aeroplane is doubled, the power output will increase by 8 times (2^3 = 8).

P=F×v ... D=drag force=bv^2 ....
P=b × v^2 × v ... P= bv^3 ...
hence P is directly proportional to v^3 as b is a constant....
P=b × v^2 × v ... P= bv^3 ...
hence P is directly proportional to v^3 as b is a constant....
