Paper snake spins in which direction when hung near a burning candle?a...
Explanation:
When the paper snake is moving in an anti-clockwise direction, the air is flowing downwards. This can be understood by considering the concept of air resistance.
Air Resistance:
Air resistance is the force that opposes the motion of an object as it moves through the air. It is caused by the collision of air molecules with the surface of the object. When an object moves through the air, the air molecules exert a force on the object in the opposite direction to its motion.
Direction of Air Flow:
In the case of the paper snake moving in an anti-clockwise direction, the air flow is downwards. This is because the air molecules collide with the upper surface of the moving snake, exerting a downward force on it. This downward force is due to the air resistance acting on the snake.
Effect of Air Flow:
The downward air flow creates a pressure difference between the upper and lower surfaces of the snake. This pressure difference causes a lift force to be exerted on the snake, pushing it downwards. This lift force is responsible for the downward motion of the snake as it moves in an anti-clockwise direction.
Conclusion:
In conclusion, when the paper snake is moving in an anti-clockwise direction, the air is flowing downwards. This downward air flow creates a pressure difference that exerts a lift force on the snake, causing it to move downwards.

When the snake is moving in a clockwise direction, it means the air is moving upwards. When the snake is moving in an anticlockwise direction, it means the air moving downwards.
