It is normally the very "why" questions that normally students would tend to ask. Although I am not an expert at this question, please do correct my answer:
The surrounding air will get heated up by the burning fame of the candle. The hot air will rise up and some air will rise up the to the spiral and thus, it will cause the spiral to spin.
Normally, students would tend to think that it must be related to unnatural and will be frightened. I hope you would understand what I meant and do not mislead yourself.
Spin A spiral dive is just a spiral dive and should not be confused with a spin. If a pilot can not see the horizon, because of clouds for instance, he may not appreciate that he is going into a spiral dive and this can lead into a 'graveyard spiral'
Looking at the spiral staircase just made my head spin. The quarterback threw a perfect spiral.
It is called a 'spin'
Heat causes air to rise by convection. As the air rises it applies pressure to the underside of the blades. This causes the paper spiral to spin.
spiral fox is stronger because defense type beyblades can spin longer than attack types
Your player 'turning' movement is bound to your computer mouse. To spin, simply circle your mouse around your character.
Spiral grooves cut into the inside of the barrel- known as rifling.
Airplanes--not just of the paper variety, spiral for all sorts of reasons. Instability may be a cause, or perhaps the aircraft has stalled and entered a spin.
The lands and grooves in the barrel that impart spin to the projectile
Heat increases the momentum of electrons and randomizes their spin orientation. Randomized orientation of spin reduces the magnetism.
yes the fan does spin when the heater is on. this allows the hot air to be pumped through the house and the new air to be heated.
There are spiral grooves engraved on the inside of a rilfe or pistol barrel. When a bullet is fired, it is forced into those grooves, which impart a spin to the bullet. The grooves are called rifling.
