4. if the kitty hawk flyer has 12 hp, do some research to find out how to express this power in the si system and report the numerical value in kilowatts.

Explanation:

The Kitty Hawk Flyer has 12 HP. We need to express this power in the SI system and in kilowatts.

The SI unit of power is watts and HP is also one of the unit of power. The relationship between the watts and horse power is :

1 HP = 745.7 watts

To convert 12 HP to watts we will use the above relation. So,

12 HP = 8948.4 watts

Also, 1 kilowatts = 1000 watts

So, 8948.4 watts = 8.94 kilowatts

Hence, this is the required solution.

force tends to be low and long diustance masses are high
