Which of the following is not true about simple magnets?

62% Answer Correctly

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

This skeletal system is common in arthropods like insects, spiders, and crustaceans.

81% Answer Correctly

	bone
	exoskeleton
	vertebrate
	endoskeleton

Solution

An exoskeleton (external skeleton) is common in arthropods like insects, spiders, and crustaceans.

The number system most used in science is the:

94% Answer Correctly

	English system
	metric system
	British system
	American system

Solution

The metric system is a number system that designates one base unit for each type of measurement. For example, the base unit for length is the meter and the base unit for mass is the gram.

Carbohydrates are found in:

88% Answer Correctly

	sugars and starches
	food additives
	vegetable oils
	animal sources

Solution

Carbohydrates are major sources of energy for the body and are found in sugars (fruit, cane sugar, beets) and starches (bread, rice, potatoes, pasta).

"The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object." This describes which of Newton's laws of motion?

64% Answer Correctly

	first
	third
	second
	fourth

Solution

Newton's second law of motion states that The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. This law basically means that the greater the mass of an object, the more force is needed to overcome its inertia.
