Which of the following is not true about simple magnets?

63% Answer Correctly

	same poles repel each other
	opposite poles attract each other
	all of these are untrue
	opposite poles repel each other

Solution

Simple magnets have two poles, north and south, and opposite poles attract each other (N attracts S, S attracts N). Likewise, the same pole of two magnets repel (N repels N, S repels S). The Earth has a magnetic field and North and South Poles which enables the use of a magnetic compass to determine direction.

A major difference between sound waves and light waves is which of the following?

70% Answer Correctly

	all of these are correct
	a sound wave is mechanical while a light wave is electromagnetic
	a sound wave is much slower than a light wave
	a sound wave cannot travel through a vacuum

Solution

A vibrating object produces a sound wave that travels outwardly from the object through a medium (any liquid or solid matter). The vibration disturbs the particles in the surrounding medium, those particles disturb the particules next to them, and so on, as the sound propagates away from the vibration.
