Serggg [28]3 years ago

Answer: The term magnetism comes from the region of Magnesia, a city in Western Turkey, where Greeks found lodestones, which attracted iron pieces across the space.   It is also observed that, magnets attract as well as repel.  We can explain this dual nature of magnetic force by proposing that each magnet has two poles, north pole (N) and south pole (S).  You will observe two things during the activities:

1)      When two magnets are brought near each other, like poles repel; opposite poles attract.

2)      When a magnet is brought near a piece of iron, the iron also gets attracted to the magnet, and it acquires the same ability to attract other pieces of iron.

hope this helps u stay safe

A little girl kicks a soccer ball. It goes 10 feet and comes back to her. How is this possible?
marta [7]
A classic puzzle...

She either kicked it at a wall <em>exactly</em><em /> 10 foot in front of her, where the ball rebounded off the wall.

Or, she kicked the ball straight up, vertically, at a <em>90 degree angle,</em> where due to the law of gravity, which states that anything that goes up must come down, when the soccer ball reaches exactly 10 feet, it falls back down.
(Note: This is nearly impossible to achieve -- exactly 10 feet.)
